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 for using a portable multi gas detector
- Before using the gas detector, please read the product instruction manual carefully.
- It is strictly forbidden to open the cover and replace the sensor in the field.
- Installation, commissioning, setting and other operations must be carried out by professionals.
- Calibration checks should be carried out on a regular basis, and sensors that are beyond the effective service period and faulty should be replaced in time.
- It is strictly forbidden to use gas higher than the measuring range to impact the sensor.
- Prevent the gas detector from being dropped from a height or subjected to violent shocks.
- It is strictly forbidden to expose the gas detector to a high-concentration corrosive gas environment for a long time to prevent damage to the sensor.
- The gas detector cannot be used in a high temperature and high humidity environment. If the ambient humidity is high, a filter and dehumidification device must be added.
