Best multi gas detector

RS-MG41-1 is a portable multi gas detector developed by our company for explosive or toxic environments. The working principle of this gas detector is to detect gas by natural diffusion, and it has built-in electrochemical and combustion gas sensors, which have excellent sensitivity and excellent repeatability. It can detect four kinds of gases: oxygen, combustible gas, carbon monoxide, and hydrogen sulfide.

What do 4 gas monitors detect?

The 4 gas monitor can simultaneously detect the concentration of combustible gas-%LEL, oxygen-O2, carbon monoxide-CO, and hydrogen sulfide-H2S. It is the most widely used personal gas monitor. It can be found in industrial, mineral, medical, or confined space workers around the world.

What is gas detector calibration?

Gas detector calibration is a requirement for all gas sensors. This is the act of exposing the sensor to a target gas of a specific concentration and then adjusting the detector to correctly read the gas concentration. When the target gas is not in the air, many sensors also need to use zero gas to adjust the voltage being output. This process needs to be operated by professional technicians.

How does a multi gas detector work?

The gas enters the inside of the device through natural diffusion, is detected by the built-in gas sensor module, and converts the value into an electrical signal for output.

What does LEL mean in gas?

LEL is “Lower Explosive Limit”, which refers to the lowest concentration of combustible gas that explodes in the air when exposed to an open flame.

How many types of gas detectors are there?

Gas detectors come packaged into two main form factors: portable devices and fixed gas detectors.
