What are the suggestions for choosing a carbon monoxide detector?

The ** of carbon monoxide detector is about one or two thousand yuan per unit, the cheap ones are hundreds of yuan, and the expensive ones are thousands of yuan. The carbon monoxide detector is affected by many aspects, such as brand, category, specification, market, etc. Before choosing to buy, it is necessary to understand and compare in many aspects.

The carbon monoxide detector is a gas detection instrument with a high brightness liquid crystal indication that can be flexibly configured with a variety of different gas sensors. The instrument can continuously detect the concentration of toxic gas, oxygen, flammable and explosive gas, and observe the current gas concentration value at any time. It is widely used in petroleum, chemical, coal mining, metallurgy, papermaking, fire protection, municipal, telecommunications, food, textile and other industries.

I don't know what environment you're going to use it in?

If you're looking for something a little smaller, opt for Honeywell's TOXIRAE 3 Single Toxic Gas Detector. International brand, and small size (only the size of the palm of the hand), light weight, easy to carry, large screen LCD gas concentration. The protective performance is also good, and it is widely used in iron and steel metallurgy, industrial safety, etc.

However, now the ** market of foreign brands is mixed, if you really want to buy, it is best to find a better ** business, at least the pre-sale quality, after-sales service can be a little better. You can try Zhuhai Sfest. I have also purchased another composite gas detector there before, and I patiently explained the applicable places, how to use them and what should be paid attention to.

Look for the manufacturer, look for the brand, there are imported sensors in it. It also depends on qualifications and word of mouth.

Huawei designated the gas supplier Shenzhen Guoan.

1. As the name suggests, the pump-suction carbon monoxide detector is equipped with a small air pump, which works by means of a power supply to drive the air pump to pump carbon monoxide in the area to be measured, and then send the carbon monoxide to the instrument for detection. The pump-type carbon monoxide detector is characterized by its fast detection speed, and when equipped with an external sampling handle, it can be used for long-distance measurement of the current dangerous area to maintain the safety of personnel, and other diffuse gas detectors are the same.

2. As the name suggests, the diffusion carbon monoxide detector is that the gas in the detected area slowly flows into the instrument with the free flow of air. This method is affected by the detection environment, such as ambient temperature, wind speed, etc. The advantage of the diffuse carbon monoxide detector is that the cost is relatively low.

The working principle of pump-suction and diffusion gas detectors is basically the same, carbon monoxide is detected by a carbon monoxide sensor, and then amplified and converted into corresponding values through the circuit and displayed on the screen.

The carbon monoxide detector detects gas concentration in a natural diffusion way, using imported electrochemical sensors, which has excellent sensitivity and excellent repeatability; The carbon monoxide detector adopts embedded micro-control technology, simple menu operation, complete functions, high reliability, and the performance of the whole machine is at the leading level in China. The shell of the detector is refined from high-strength engineering materials and composite elastic rubber materials, with high strength and good hand feel.

** carbon monoxide detection alarm is composed of gas detection alarm controller and fixed carbon monoxide detector, gas detection alarm controller can be placed in the duty room to monitor and control each monitoring point, carbon monoxide detector is installed in the most vulnerable place of gas leakage, and its core component is the gas sensor. The carbon monoxide detector converts the carbon monoxide concentration detected by the sensor into an electrical signal, which is transmitted to the gas detection alarm controller through the cable, the higher the gas concentration, the stronger the electrical signal, when the gas concentration reaches or exceeds the alarm point set by the alarm controller, the gas detection alarm controller sends an alarm signal, and can start the solenoid valve, exhaust fan and other external equipment to automatically eliminate hidden dangers. Carbon monoxide detection alarms are widely used in petroleum, chemical, metallurgy, electric power, coal mines, water plants and other environments to effectively prevent accidents.

The carbon monoxide gas sensor is used in conjunction with the alarm, which is the core detection element in the alarm, and it is based on the basic principle of constant potential electrolysis. When carbon monoxide diffuses to the gas sensor, its output produces a current output that is supplied to the sampling circuit in the alarm, which plays the role of converting chemical energy into electrical energy. When the gas concentration changes, the output current of the gas sensor also changes proportionally, and the output is converted and amplified by the intermediate circuit of the alarm to drive different actuators, complete the detection and alarm functions of sound, light and electricity, and form an environmental detection or monitoring alarm system together with the corresponding control device.

Hello, carbon monoxide detector, carbon monoxide detector, carbon monoxide detector and carbon monoxide alarm belong to the same thing, the industry is called carbon monoxide detector and carbon monoxide detector, colloquially known as carbon monoxide detector, carbon monoxide leak detector, carbon monoxide alarm, carbon monoxide alarm, etc., all refer to the same thing.

Due to the different functions of carbon monoxide detectors, portable carbon monoxide detectors and fixed carbon monoxide detectors and carbon monoxide gas alarm controller hosts have emerged. With the rapid development of the gas detection instrumentation industry, there will be more professional and unified names to facilitate the use of customers.

A carbon monoxide detector is a detector that detects a single toxic gas, and is suitable for intrinsically safe gas detectors required by relevant explosion-proof locations.

Carbon monoxide detectors mainly include handheld and fixed; Some are imported and some are domestic; There are standard and optional ones.

The selection of carbon monoxide detector needs to start from the work requirements of the actual use scenario, and the handheld carbon monoxide detector is usually used to ensure the detection of carbon monoxide in the environment by on-site operators and ensure the safety of construction personnel. The fixed carbon monoxide detector is an uninterrupted detection of the concentration of carbon monoxide gas in the measured environment for a long period of time to prevent unnecessary damage caused by carbon monoxide gas leakage and ensure its safety, which is an explosion-proof product.

According to the high-precision detection standard for carbon monoxide detection in the environment, you can choose imported (high precision and stability), domestic (accurate and stable within the explosion-proof standard), or you can choose your own configuration, such as the range of detecting carbon monoxide gas leakage concentration value, etc.

Carbon monoxide detectors include handheld carbon monoxide detectors, portable carbon monoxide detectors, fixed carbon monoxide detectors, and so on. The selection of carbon monoxide detector is to select a carbon monoxide detector with appropriate inspection principle, range and resolution according to the characteristics of the on-site use environment and the purpose of carbon monoxide inspection. What is your environment like?

What is the purpose of carbon monoxide detection?

The carbon monoxide detector is divided into portable and stationary according to the method of using the anatom, and according to the detection principle: infrared detection principle, electrochemical detection principle, and catalytic detection principle.

Selection of carbon oxide detector with a cover:
