AO-K400M Portable Multi-gas Detector (CO, EX, H2S, and O2)

Reference AO-K400M

Manufacturer: Bosean

Condition: New

The AO-K400M portable multi-gas detector can measure 4 gases: CO, EX, H2S and O2 in its Standard configuration.

It can also be configured from the factory to detect: a combustible gas, O2 and two other types of toxic gases continuously and simultaneously. Consult prices for these other gas combinations.

K-400M is widely used in areas where explosion-proof or toxic gas leak-proof instruments are required, such as in underground channels or in the mining industry, to protect the lives of workers and prevent damage to used equipment.
