QGM 4-gas portable detector

QGM 4-gas portable detector

4 in 1: this multi-gas detector monitors the oxygen level (O2) and the concentrations of hydrogen sulphide (H2S), carbon monoxide (CO) and explosive gases (LEL).

Fitted with an audible, flashing and vibrating alarm system, it is triggered when the concentration threshold of these gases is exceeded.

This detector measures STEL (short-term exposure limit) and TWA (time-weighted average exposure) values.

Its rechargeable lithium battery provides long battery life of up to 24 hours.
