The concept of humidity

Scientists often use relative humidity to describe the amount of moisture in the air. Simply put, imagine that air is a towel. If you pour a glass of water, you can use a towel to soak it up.

The amount of water vapor in the air is only a fraction of what can be contained in the air, so the relative humidity is a percentage. When the relative humidity is one hundred percent, the air is saturated.

Like a wet towel, the air can no longer take moisture. When the relative humidity is 100 percent and the air is saturated, evaporation and sedimentation are in equilibrium. Reaching equilibrium again illustrates the increased amount of evaporation, as a moisture precipitate.

The so-called temperature and humidity meter has long been eliminated, and now they all use the automatic temperature and humidity monitoring system, you are also very suitable for breeding, I deal with many pharmaceutical companies and mushroom growers, many of them use a company called Beijing Zhixiang Lingyu, some places have offices, it is said that it is fully automatic, and there is no need for manual operation at all.

This depends on whether you are home or professional measurement, each has a different one, foreign ones are more expensive, generally hundreds of dollars, the more well-known domestic virtue brand, because I myself do aquatic products, so the temperature and humidity meter is often used, the virtue brand is also my personal is the most used, the error is relatively small, basically in the degree or so, the quality is relatively good, I myself have used some of the four or five years or the same in use, so in general, want the most cost-effective when buying virtue. Recommend their TH-201 series products.

Use the supplied communication cable to connect the recorder to the serial port of a general computer (PC586 or higher).

Run the recorder application on the computer, and set the recording start time, recording cycle, stop time, stop mode and other parameters of the recorder.

After the setting is completed, disconnect the recorder from the computer and place the recorder in the place to be detected.

Question 1: Which brand of thermohygrometer is better The better brands of thermohygrometer are Yipin Boyang, Kejian, Gemlead Hazelly, Meideshi, Oudashi, Mingle Minggao, Pinyi, Emate, KTJ, Shentuo, Deli, Baoyi, Dretec, Hegao, Xiaobaixiong, and Kerde

Question 2: Which is the best brand of household electronic temperature and humidity meter I use at home is the Defu TH160 Gold Supreme Temperature and Humidity Meter, and the calibration certificate is very accurate.

Question 3: Which brand of temperature and humidity meter is good for home temperature and hygrometer household Delian or Huasheng Zhongwang Technology electronic humidity thermometer.

Digital display electronic thermometer, can be divided into indoor and outdoor two, indoor is generally built-in sensor, outdoor is external sensor, this is the difference on the premise, at the same time, the indoor thermometer measurement temperature can not be below -10 degrees and above 65 degrees of the environment work, and the late fiber outdoor can, because he is through the probe line to measure the temperature, not the machine to measure the temperature, so if you want to measure high temperature and low temperature, just pull the probe to the measurement place. The machine itself does not need to be placed in a hot or low temperature area, so if you need to measure higher or lower temperatures, you need an external sensor. The product introduction of Huasheng Zhongwang Technology is relatively complete for this kind of products, and it can be borrowed.

Question 4: Temperature and hygrometer, which one is better for home diving was shipwrecked and never came back!

Temperature and humidity recorders are now developing rapidly, and more models and functions have been extended for different occasions. It is indeed difficult to choose. Here are a few comments for you, of course, you can ask Zhituo Instruments, you know.

Cold chain logistics and transportation: GPRS transmission, this equipment needs to install a mobile phone card, warehouse, warehouse, computer room: temperature and humidity recorder can be wall-mounted, conditional can choose the alarm type (SMS alarm + power failure alarm + remote query).

Pharmacies use temperature and humidity recorders: portable temperature and humidity, the cheapest kind will do.

The selection of temperature and humidity recorder needs to refer to the use of occasions, the use of Zhituo instrument temperature and humidity recorder selection has 1, wireless temperature and humidity recorder, mainly used in cold chain transportation, refrigerator monitoring 2Stand-alone temperature and humidity recorder: mainly used in:

Warehouses, pharmacies, agricultural research 3SMS alarm temperature and humidity recorder: mainly for some important occasions to notify and warn in time.

You see what occasion it is used for, and then you make a choice.

Looking at the function, in the pharmaceutical GSP certification, it is necessary to have the following functions to meet the standard:

1.The monitoring data is uploaded to the monitoring software from time to time, 2The equipment has the function of local sound and light alarm, 3The device itself has a data recording and storage function, 4The temperature and humidity accuracy should meet the accuracy standards of the relevant library type.

This depends on the needs of the user and the occasion in which the user uses it. Do you want to bring an LCD display, do you need to be waterproof, upload through the network or upload via the 485 line? I have used the products of Kenda Renke, the equipment configuration is simple and comprehensive, and the software is free to use.

I use rs-ws-n01-2 products are waterproof shell upload data through wireless wifi, there is a curve chart display on the software and you can also print the data**. The accuracy is very accurate, and the technical support is in place! Highly recommended!

It's not a matter of the model, it's a question of the accuracy and measurement range you need.

Wireless Management Host:It can receive 32 wireless measurement point signals and upload them to the software platform through 485 mode. The wireless small host has a Chinese large screen LCD that can display real-time data.

It comes with a powerful SMS function, which realizes SMS alarm for temperature and humidity overrun, SMS alarm for power failure, supports up to 5 contacts, real-time SMS inquiry and monitoring real-time value, and external high-power sound and light alarm can realize local sound and light alarm for abnormal situations. The small host comes with a data storage function, which can store up to 140,000 pieces of data, ensuring uninterrupted storage and recording of data in the case of computer shutdown or crash.

Radio large screen LCD display temperature and humidity recorder:With the waterproof power supply, it can be connected to the nearest 220V AC power, the temperature and humidity transmitter, large-screen LCD display, radio frequency hopping transmission, and completely free of wiring. The built-in buzzer of the device has the function of local sound and light alarm, automatic storage mode, automatic storage when the communication is interrupted, and the storage data can be continued after the communication is restored, with a maximum storage capacity of 65535.

Users should determine the number of temperature and humidity transmitters according to the actual site needs. According to the actual situation of the site, the built-in probe type is selected for the normal temperature storage equipment, and the external probe is selected for the cold storage equipment.

You can choose a large display and a practical one.

It's best to choose a large screen display, ***.
