FAQs

Q1: What is a gas detector?
A1:
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: 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: What is ppm of gas detector?
A3: 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.

5 Tips for Using a Handheld Gas Detector

  1. Carefully read the instruction manual corresponding to the gas detector before the operation, and be familiar with the performance and operation methods of the machine.
  2. Check whether the battery power is sufficient. If the battery power is found to be insufficient, replace the battery in time.
  3. Check whether the air filter of the air inlet is blocked by debris and whether the blockage needs to be cleaned or replaced.
  4. Press and hold the start button for three seconds during startup to enter the self-test state, and observe whether the low alarm value and high alarm value of the detector are set accurately (the first-level alarm of the CO detector is 50ppm, the second-level alarm is 100ppm; the oxygen detector one The first-level alarm reports 19.5%, the second-level alarm reports 22%; the first-level alarm of the hydrogen sulfide detector is 10 ppm, and the second-level alarm is 15ppm).
  5. During the self-inspection during the boot process, you should listen to the grading alarm sound and light alarm and vibration alarm for accuracy.
  6. Observe whether the initial value is accurate after starting the machine under fresh air conditions (the initial display of the CO detector is 0 ppm; the initial display of the O2 detector is 20.9%; the initial display of the hydrogen sulfide detector is 0 ppm).
