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 calibrate fixed gas detector?
- The calibration personnel must be trained, understand the principle and performance of the fixed gas detector, be proficient in operating skills, and hold a certificate.
- Adjusters must strictly abide by the operating procedures.
- The fixed gas detector must be measured and certified before it can be used.
- Before calibrating the fixed gas detector, perform a visual inspection. Calibration can be performed after confirming that the appearance is intact.
- Fixed gas detectors that require calibration should be warmed up for about 20 minutes. Set the fixed gas detector to zero in fresh air.
- After the zero adjustment is completed, pass a standard gas sample with a concentration of about 1.0% according to the flow specified in the manual. Calibrate the displayed value of the fixed gas detector. The indicated value is consistent with the standard gas value and can be used after stabilization.
