Q1: What is a fixed gas detector?
A1: The fixed gas detector is composed of sensors and transmitters, and is installed at the detection site. The secondary instrument consisting of circuit, power supply and display and alarm device is installed in a safe place, which is convenient for staff to monitor. In industrial installations and production processes, fixed gas detectors are generally used, because fixed gas detectors can be installed at specific detection points to detect specific gas leaks.
Q2: What does a gas detector detect?
A2: Combustible gases: Natural gas (methane), liquefied gas, coal gas (hydrogen), acetylene, pentane, alkynes, acetone, toluene, alcohols, hydrocarbons, light oil, etc.
Toxic gases: Carbon monoxide, hydrogen sulfide, ammonia, chlorine, oxygen, phosphine, sulfur dioxide, hydrogen chloride, chlorine dioxide and other toxic and harmful gases.
Q3: Difference between fixed gas detector and portable gas detector
A3: The biggest advantage of fixed gas detectors is 24-hour uninterrupted measurement. As long as the power is turned on, the fixed gas detector is in normal detection work. Portable gas detectors are usually used in confined spaces and confined spaces, but the gas environment in these spaces is usually very complex, and there will be situations such as lack of oxygen and high concentrations of harmful gases.
Tips: How to maintain H2S gas detector?
- Regularly calibrate, test and check the H2S gas detector. In general, the calibration frequency is once a year.
- As the most important part of the hydrogen sulfide gas detector, the sensor should try to avoid contact with the gas generated by inorganic solvents or organic solvents. Especially for electrochemical sensors used to detect toxic and harmful gases, the evaporation or pollution of the electrolyte will cause the sensor signal to drop and shorten the service life of the hydrogen sulfide gas detector.
- The sensor dust cover is used for protection. In order to prevent the dust cover from being blocked by dust and affecting the use of the sensor, it should be cleaned regularly.
- When installing the H2S gas detector, do not place the hydrogen sulfide gas detector against the wall, and reserve enough space around it for routine maintenance and troubleshooting.
- Please ensure that the H2S gas detector is in a dry state to avoid affecting the detection accuracy and service life of the hydrogen sulfide gas detector due to humidity.
- The entire exterior of the H2S gas detector needs to be kept clean. You can wipe the surface with a soft damp cloth. Do not use a damp cloth with water droplets to prevent water droplets from splashing into the hydrogen sulfide gas detector.
