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: What are the available measuring ranges for the fixed carbon monoxide (CO) gas detector?
The fixed carbon monoxide (CO) Gas Detector offers multiple measuring ranges to meet different application needs, including 0–10 ppm, 0–20 ppm, 0–50 ppm, 0–100 ppm, 0–1000 ppm, 0–2000 ppm, and 0–5000 ppm. Lower ranges are ideal for environments requiring high precision and early CO leak detection, while higher ranges are suitable for industrial sites or confined spaces with potential for high CO concentrations.
