Gas Detector Software
Q1:Â What is a gas detector?
A1:Â A gas detector is an instrument for gas leakage concentration detection, including a portable gas detector, handheld gas detector, fixed gas detector, online gas detector, etc.
Q2:Â What does a gas detector detect?
A2:Â 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:Â What is ppm of gas detector?
A3:Â Parts per million or "ppm" is often used as a fractional measure of concentration. For example, a methane (molecular) concentration of 2% means that 2 out of every 100 air molecules are methane. Likewise, a methane concentration of 2 ppm means that 2 out of every 1 million air molecules are methane.
Tips: How to choose a suitable gas detector?
- Own needs. What gas do I need to detect? Depending on your needs, decide whether to purchase a stationary detector or a portable gas detector.
- Surroundings. All kinds of gas detectors have strict requirements on the on-site environment. Generally speaking, the temperature is -20~60℃, the humidity is 0-95%RH, and the pressure is 80-120Kpa, etc., including dust and flow.
- Security situation. There are explosion-proof requirements on the site where the gas detector is installed and used. The coal, petroleum and chemical industries have strict requirements for explosion protection, and gas detectors are required to have explosion-proof certification.
- Function. The general function of the required gas detector is to detect gas concentration and alarm when it exceeds the standard. Signal output is one aspect, and it is necessary to need current output, digital signal output, voltage output and switch output. There may be some other special requirements, such as a USB interface and Bluetooth connection.
