How do I use a combustible gas detector correctly?
Combustible gas detector, a detector that responds to single or multiple combustible gas concentrations. There are two types of combustible gas detectors: catalytic type and infrared optical type. When combustible gas enters the detector, it causes an oxidation reaction (flameless combustion) on the surface of the platinum wire. The heat generated increases the temperature of the platinum wire, and the resistivity of the platinum wire changes. So how to use the combustible gas detector correctly?
How to use combustible gas detector correctly?
1. Press the power-on button of the combustible gas detector and wait 30-60 seconds. After the combustible gas detector is fully started and all values on the display screen show normal, you can proceed to the next step.
2. Place the handheld combustible gas detector away from the environment to be detected and wait for about 3 minutes. After the combustible gas detector has fully detected the leakage concentration of combustible gas in the environment, the specific concentration value of the combustible gas will be displayed on the display. The measuring range is 0-100%LEL. If the detected combustible gas leakage concentration is greater than 25% LEL and less than 50% LEL, the combustible gas detector will issue a low alarm. When the weak country detects that the combustible gas leakage concentration is greater than 50% LEL, the combustible gas detector will send out high-frequency audible and visual alarm signals to improve on-site operators' control of combustible gases in the environment, so as to achieve safe and efficient production.
3. After using the combustible gas detector, in addition to shutting down normally and charging in time for battery life, the combustible gas detector also needs to be effectively maintained: usually zeroing the value, cleaning the instrument, especially the head of the combustible gas detector. The sensor location needs to be cleaned of dust in time, because many on-site operating environments are relatively harsh, and small particles of dust can easily cause clogging of the combustible gas detector sensor and affect the sensitivity of the detector.
