With various options available, the GasAlert Micro5 is a versatile and good value gas detector featuring extended capability and protection from up to five potential atmospheric hazards including oxygen, combustible and toxic gases. The compact and lightweight detector is unparalleled in its capabilities and designed to support various different applications.

The BW Micro 5 has extensive configuration options, including data logging, alkaline or Li-Ion battery options, 1 to 5 gas sensor configurations plus PID (VOCs) and as such there is sometimes a greater lead time on some model options.
