Thermal conductivity detector (TCD) is a concentration-type detector that responds by using different thermal conductivity coefficients of the measured component and the carrier gas. Some are also called hot wire detectors (HWD) or thermal conductivity meters and katherometer Or Catherometer), it is a well-known overall performance detector, which belongs to the method of physical constant […]

Importance of Installing Explosion-proof Gas Detectors in Boiler Rooms
The main component of natural gas is methane, which is a flammable and explosive gas. If natural gas leaks encounter open flames, static electricity, lightning, or improper operation, explosions and fires may occur, and people in a confined space will lack oxygen, suffocate, and even die. Installing natural gas alarms can effectively prevent explosions and […]
Signal Transmission Distance of Gas Detector
The fixed gas detector consists of an alarm controller and a detector. The controller can be placed in the duty room and mainly controls the monitoring points. The gas detector is installed in the place where the gas is most likely to leak. The core component is a built-in gas sensor. The sensor detects the […]
Principles of Gas Sensors
The key component of a gas detector is a gas sensor. Gas sensors can be divided into three categories in principle: Gas sensors using physical and chemical properties: such as semiconductor type (surface control type, volume control type, surface potential type), catalytic combustion type, solid thermal conductivity type, etc. Gas sensors using physical properties: such […]
“New Technology” Used in Carbon Dioxide Detectors
At present, there is a lot of carbon dioxide in the development of many coal mines. If you do not enter the coal mine for a long time, you cannot rush in. First of all, you need to test the concentration of carbon dioxide. Now people control the air quality in the underground shopping malls, underground […]
Oxygen Sensing unit Kinds
Today’s o2 analyzers utilize one of any various kinds oxygen devices. As commercial approach applications involve increased measurement accuracy and reliability and repeatability, users may also be demanding analyzers which require at least servicing and calibration. To this end, customers of fresh air analyzers should evaluate the benefits of any specific fresh air sensor enter […]
The real difference electrochemical and zirconia sensors
Avcray fresh air analysers are particularly ideal for applicationssuch as inert gasoline blanketing, additive developing, glove cases, metal heating treatment and research and advancement projects. There are two varieties of fresh air sensors found in the Avcray fuel analyse collection, these include zirconia and electrochemical, despite the fact that most of the Avcray fuel analysers […]
Measurement and Application of Mixed Gases
Ultrasonic gas measurement technology realizes the measurement of mixed gas, long life, high precision, and maintenance-free, which ensures the stability of the mixed gas concentration. Measurement and application of mixed gas, tests have confirmed that after adding a certain amount of another gas or two gases to one gas, it can be used to refine […]
Main Features of Infrared Gas Analyzer
Can be automatically adjusted according to the surrounding air (depending on the measured component) High efficiency does not require calibration gases and accessories. Multi-layer detection guarantees high degree of sensitivity and small lateral sensitivity. The sampling unit is easy to clean and reduces maintenance costs. Humanized WINCE operating system, data is automatically stored. Open interface […]
Introduction of Dust Monitor
The dust monitor is mainly used to detect the dust concentration in the environment. At present, people have higher and higher requirements for living, working and living environments. The working principle is mainly the microcomputer laser and the AC electrostatic induction principle. It is mainly applicable to various research institutions, meteorology Public hygiene, industrial labor […]
