Can a nitrogen cabinet without a temperature and humidity indicator be used?

No, because you can't see the number set, how to set it!

1.A prerequisite for the use of this product is that the ambient humidity must be greater than the set humidity value. The effect is better when the set humidity value is relatively high, such as 45%Rh, and when the external environment is greater than the set value of 20%Rh or more.

If the humidity value you need is not higher than 10%rh of the external environment, it is recommended that you open the cabinet door and close the cabinet door when the ambient humidity is high. If the humidity value you need is equal to or lower than the ambient humidity, it is recommended that you unplug the power supply and wait until the ambient humidity is high before using it. When the humidity requirement is about 40%Rh, the ambient temperature is higher than 60%Rh.

2.The temperature sensor used in the digital display electronic moisture-proof cabinet is a large humidity sensor manufacturer Honeywell (H0Neywell) brand sensor, which has the advantages of high precision, less annual drift, strong anti-interference ability, etc., and the humidity display error is within plus or minus 2%rh.

If the customer uses his own humidity tester to test the humidity and the humidity display of this product is inconsistent, this product can be corrected, and this product has a humidity correction function. However, it is recommended not to carry out humidity correction as much as possible, first of all, to see whether the humidity tester you use is produced by a regular manufacturer, and the general humidity tester should be calibrated once every 6 months in the instrument measurement and inspection center recognized by the state, so as not to increase the error.

3.For the ultra-low humidity electronic moisture-proof cabinet with customer demand below 10%RH, the empty container can reach about 3%RH, and 1%RH is an ideal state. Generally speaking, for electronic moisture-proof cabinets that have been placed in items, the humidity is below 10%, and the storage conditions have been *.

4.It is normal for the surface temperature to be slightly higher during the operation of the dehumidifying movement, so please do not mistake it for a dehumidifying movement fault.

Yes, but if you're not at ease, you can buy yourself a humidity monitor and keep it in your wardrobe.

When the humidity exceeds the set value, it will automatically spray nitrogen, and when the humidity reaches the set value, it will automatically stop, so as to effectively protect the items and save energy.

Microcomputer control, digital display of temperature and humidity, humidity display value of 1%-99%. The temperature display value is 1-99.

1. Display mode: imported component display, temperature and humidity display at the same time, intuitive and clear, stable performance.

2. Cabinet structure: special closed cabinet for nitrogen cabinet, professional design with good air tightness, and no deformation when storing heavy objects. Comes with casters and brackets for easy movement and positioning. Multi-layer anti-rust paint treatment, strong anti-corrosion, wear-resistant and not easy to fall off, steel plate thickness.

3. There are three special steel partitions for nitrogen cabinets, which are safer to store heavy objects.

4. Nitrogen saving device: using microcomputer automatic induction control, with the use of customer nitrogen, after the humidity exceeds the set value, it will automatically inject nitrogen, and when the humidity reaches the set value, it will automatically stop.

An industrial nitrogen cabinet is a device used for the storage and transportation of industrial liquids (ammonia, hydrogen, etc.).

A nitrogen cabinet is a type of loading cluster used for the storage and transportation of inert gases (helium, etc.).

The nitrogen cabinet exists as an auxiliary equipment for pressure vessels, such as compensators in storage tanks or pipelines, to eliminate the stress caused by thermal expansion and cold contraction of vessels or pipelines; Install a slow tamper after the valve shoots the letter cherry before to reduce the vibration of the valve; used as a pressure reducing valve in high-pressure systems; When the system needs to release a small amount of residual pressure, it is used as a safety valve, etc.

Nitrogen cabinets can also be used as accessories to other equipment.

For example, the air separation system is matched with an air compressor to obtain a high-purity product after compressed air purification to meet the user's requirements; The high-temperature gas emitted from the compressor is used for drying, which improves product quality and yield.

Nitrogen to achieve moisture-proof, mildew-proof, anti-oxidation, anti-rust, anti-micro moisture absorption and other purposes, nitrogen cabinet mainly uses a variety of dehumidification technology, and then effectively reduce the internal humidity of the cabinet, so as to achieve moisture-proof, mildew-proof, rust-proof, anti-micro-moisture absorption and other purposes, can effectively protect the period, especially the protection of cultural relics.

The principle of use of nitrogen cabinet:

Nitrogen cabinets are widely used in the electronics industry. They usually require an ultra-low humidity environment, but cannot be dehumidified. This is mainly achieved by pouring the air of oxygenated air into the nitrogen replacement box in a sealed box.

A big problem with the use of nitrogen storage cabinets is that their operating costs are still relatively high. For example, if the box volume is 1,450 liters and the flow rate is 85 liters per minute, about 90,000 yuan of nitrogen is consumed per year.

What you are asking is, is there any impact if the air compressor is not installed with instruments? It doesn't matter. But you can't regulate the pressure unless you just do a job. It doesn't cost much to buy a barometer and install it.

Nitrogen storage cabinet is a nitrogen protection cabinet with oxygen concentration monitoring, which is suitable for storing finished products, semi-finished products, raw materials and appliances in the process of semiconductor device process production.

1. Dehumidification principle: The dehumidification principle of fast ultra-low humidity moisture-proof cabinet is completely different from the traditional passive electronic dehumidification method; Deep dehumidification technology is used to feed ordinary compressed gas.

It is dried again and the obtained ultra-dry air is injected into the cabinet. The method of rapid gas exchange is used to replace the moisture of the cabinet with dry gas; Electronic moisture-proof box: pro.

Use a hygroscopic agent (currently generally a molecular plug and other materials) to passively absorb the moisture in the cabinet, and periodically heat and regenerate the hygroscopic agent, and then start the moisture absorption again;

Second, the dehumidification effect is fast and ultra-low humidity? 1.Rapid dehumidification: Regardless of the surrounding environmental conditions and the compressed air, it can be achieved from indoor humidity within 10-15 minutes.

10%RH, and then use the ultra-low humidity environment to protect the material from moisture and oxidation. Electronic moisture-proof box: 1Passive dehumidification with a hygroscopic agent is used to adsorb off the vicinity of the hygroscopic agent first.

The moisture is then slowly dried throughout the cabinet using the principle of diffusion of water vapor 2Since the dehumidification device does not need to be regenerated, the dehumidification process is not interrupted, so the low humidity state is stable.

There will be no fluctuations 2The electronic dehumidification movement is regenerated and heated by the material of the movement, so the humidity in the cabinet fluctuates during regeneration.

3. Continuous dehumidification fast ultra-low humidity moisture-proof cabinet:The dehumidification is continuous without fluctuation, and the dehumidification speed is fast, which fully meets the frequent opening of the door 4In the occasion with high anti-oxidation requirements.

It can also be filled with nitrogen to achieve a very ideal moisture and chemical resistance. Electronic moisture-proof box: 3The electronic dehumidifying movement does not absorb moisture at the time of regeneration, that is to say, in the big rear.

During the regeneration time of about 1 hour out of every 6 hours, if the humidity of the door opening rises to a relatively high humidity, it will not immediately return to 5%RH and is not suitable for frequent door opening.

Occasion, 4The ultra-low humidity effect is relatively poor, the dehumidification speed is relatively slow, and the anti-oxidation performance is relatively poor. It is more suitable for occasions with less door opening, moisture-proof and anti-oxidation requirements.

Fourth, the equipment parameter performance is fast and ultra-low humidity moisture-proof cabinet: Low humidity uniformity Due to the active dehumidification method of air replacement, the dry air in the cabinet flows well and the low humidity is uniform.

good sex; Electronic moisture-proof box: especially after placing the items, it is more obvious to passively absorb moisture, and the air flow in the cabinet in the low humidity state is not good, and the uniformity is relatively insufficient; Fast ultra.

Low-humidity moisture-proof cabinet: A: The control and display adopt high-precision digital control and display, with an accuracy of 3%RH; Humidity control is fully automated, electronic moisture-proof box: another.

With energy-saving control device, the display error is large, in order to achieve the setting value of 5%RH on the display, some errors even reach 8%RH-15%RH; Some brands are inflated.

Anti-static measures cannot be controlled automatically.

The automatic nitrogen cabinet is a cabinet that uses nitrogen to achieve the purpose of anti-oxidation and moisture-proof, and the closed cabinet itself has a channel for nitrogen supply and exhaust. Different control functions can be configured according to application requirements, and are widely used in microelectronics, semiconductor and other industries. The electronic moisture-proof box cabinet itself must have good air tightness, in addition to effectively preventing external humid air from penetrating into the cabinet inside.

With the continuous development and innovation of moisture-proof technology, moisture-proof dehumidification equipment is becoming more and more innovative, and the more popular moisture-proof equipment on the market is the electronic moisture-proof box and automatic nitrogen cabinet, many people will confuse the two, in fact, the difference between the two is still very large.

The automatic nitrogen cabinet is mainly reflected in the function of being filled with nitrogen, and its main role is to prevent oxidation.

A nitrogen refillable is the main difference between the two, and the second difference is that for humidity control, the humidity and low humidity in the electronic moisture-proof box can be controlled, while the nitrogen cabinet is fully automatic for humidity control, and its humidity control range is 1%-60%. The nitrogen cabinet needs to be equipped with nitrogen by itself, which will incur a certain cost when used, and the electronic moisture-proof equipment has the effect of energy saving. Both have the role of split rock storage, and both have their own advantages and disadvantages.

The electronic moisture-proof box is mainly divided according to humidity control, there are three types, medium humidity, low humidity, and ultra-low humidity.

This is useful for storage ICs, BGAs, precision electronic components, specialized medicines, semiconductor devices, optical electronic devices, printed circuit boards, optical films and lenses, precision instruments and meters, etc. Especially for electronic products, the storage of cameras and mobile phones is a very good choice.

No.

You need to connect to the host and dial the bridge number to access the Internet.

Light cats. It refers to a transceiver device that converts optical Ethernet signals into other protocol signals, and optical modems are also known as single-port optical transceivers.

It is a product designed for special user environment Hengdan, which uses a pair of optical fibers to carry out single E1 or single or single 10BaseT point-to-point optical transmission terminal equipment. Tell the silver to disturb.

3 allIt can be used, but it generally requires other external equipment, such as set-top boxes, stereos, etc. It is still recommended that you connect to the host, because the monitor itself is used for display, and other functions are actually not convenient. Second, the brightness is obviously not as good as TV.

3. The response time is not as fast as TV, and some high-speed scenes may have tailing.

Fourth, the viewing angle is obviously not as good as TV, and it can only be watched in the first part, which is not suitable for multi-person families.

Fifth, there is no wired interface itself, you must buy a TV box and then connect it to the set-top box for use.

Seventh, the display is mostly soft screen, there is no solid TV, and families with children are more worried.

Displays have always been a single-function product, and our attention to it has been mainly focused on screen size, refresh rate, response speed, etc. Recently, Samsung launched a new smart display, the biggest feature of this monitor is the built-in Samsung Tizenos system, which can run independently without the connection of the computer host and mobile phone. You don't need a host to run!

Samsung launches smart monitor with Tizenos, which is available in 27-inch and 32-inch versions, with a narrow front bezel and a design that focuses on business simplicity. Samsung's smart display has a built-in Tizenos system. This is not a customized UI developed based on Android, but an operating system developed by Samsung itself, which should be familiar to Samsung ecological users, and Tizenos is currently mainly used in smart TVs, watches and mobile phones.
