What is 4 in 1 gas detector?

4 in 1 gas detector for multi gas

4 in 1 gas detector ( RS-MG41-1) is an intrinsically safe composite detector developed by our company for environments containing explosive or toxic gases. The gas detector uses a natural diffusion method to detect the gas and an electrochemical combustion gas sensor. It has excellent sensitivity and excellent repeatability. The product can detect four gases: oxygen, flammable gas, carbon monoxide, and hydrogen sulfide. 

portable multi gas detector features:

1. The 4 gas detector uses electrochemical and catalytic combustion sensors with excellent sensitivity and repeatability

2. The 4 in 1 gas detector shell has high strength and belongs to intrinsically safe explosion-proof products.

3. High-definition color screen design, easy to check the gas status

4. The 4 in 1 gas detector can detect four gases: oxygen, flammable gas, carbon monoxide, and hydrogen sulfide

5.Can set high and low limit alarm value

6. Full-featured self-test, the product adopts sound-light vibration three-level alarm

7. Shortcut key to quickly turn on and off audible alarm and storage mode

8. Up to 130,000 stored data, with the software to view historical data at any time

9. Large-capacity battery, the device can be used continuously for at least 8 hours in the constant light mode
