Handheld Small Light Portable Multi Gas Detector H2s / O2 / Co / Ex Diffusion Type
HY20D4 Four in One Portable multi gas detector CO/ O2/H2S/LEL OVERVIEW Portable multi gas detector could detect combustible gas, O2 and other two types of toxic gases continuously and simultaneously. It is widely used in areas 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 to the relevant equipment. FEATURE 1) Advanced MCU control with low power consumption 2) Adjustable
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 the wrong operation
13) Explosive proof housing
