Portable industrial multi 4 gas detector for CO H2S O2 and CH4 combustible gas
portable multi gas detector could detect combustible gas, O2 and other two types toxic gases continuously and simultaneously. It is widely used in the area where explosion-proof is required or toxic gas leaks, like underground channels or mining industry, so as to protect the workers' life and avoid damage on the relevant equipments.
1) Advanced MCU control with low power consumption
2) Adjustable low and high alarm level
3) Adjustable calibrating level
4) High concentration protection for combustible gas
5) Self test for the combustible gas sensor
6) Low battery indication
7) Replaceable sensor module
8) Self-adjustment function
9) Visual and audible alarm with vibration
10) STEL and TWA alarming for toxic gases
11) Advanced self-examination and self-renovation function
12) Password management to avoid wrong operation
13) Explosive proof housing
This CD4-PE model for multi gas detecting alarm is applied to underground coal mine, petrochemical industry, municipal, environmental protection and other spaces where it need to detect multi gases. This device can detect methane (ch4) or combustible gas(LEL ), oxygen (O2),carbon monoxide (CO) and hydrogen sulfide (H2S) at the same time. When the concentration of any gas in the environment is higher than the setting alarm point of concentration, this device will send out the sound and light alarm to warm users who wears it to do some protective work. This device can be hand-held to use and also can be fixed to use. It’s a type of mine explosion-proof intrinsically safe, and the explosion-proof sign is Exibdl.
