SISCO Gas Detector Catalogue.pdfQ1: 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 should I do if my gas detector shows an unexpected high PH₃ reading?
- Check for any potential sources of phosphine gas nearby, such as chemical storage, fumigation processes, or leaks.
- Inspect the sensor for contamination, dirt, or physical damage that may affect its performance.
- Improve ventilation to eliminate any trapped gas and see if the reading decreases.
- Perform a calibration with a known concentration of PH₃ gas to verify accuracy.
- If the issue persists, the sensor or internal components might be faulty. Consult the user manual for troubleshooting guidance or contact the manufacturer's support team for repairs or sensor replacement.
