Description / Features / Spec


BW GasAlert Max XT II LEL (Filtered), O2, H2S, CO Multi Gas Detector with Rechargeable Battery and Yellow Housing, UK

The GasAlertMax XT II is another robust and reliable multi gas detector from BW Technologies.  It features four sensors for combustible gases (LEL – filtered), oxygen (O2), hydrogen sulphide (H2S) and carbon monoxide (CO).  It also has a bright, yellow casing.

This monitor is cost-effective and has a motorised pump which is used for remote sampling.  This feature is great for confined space applications due to its reliable diaphragm technology.  Despite being compact and lightweight the GasAlertMax XT II is tough and water-resistant with a concussion-proof boot.  The risk of certain gases is minimised with this monitor, ensuring workers feel safe and benefit from continuity and productivity.
