BW GasAlertMicro 5 PID, Pumped, LEL(F), O2, CO+H2S, VOC (PID) Multi Gas Detector with Rechargeable Battery and Yellow Housing, UK

Detect up to five hazardous gases including volatile organic compounds (VOCs) with the GasAlertMicro 5 from BW Technologies. This is a multi gas detector and features the following sensors: PID, LEL (filtered), oxygen (O2) and a combination sensor for carbon monoxide (CO) and hydrogen sulphide (H2S). This particular version is also a pumped instrument and has a rechargeable battery.

The monitor comes with a bright yellow casing which enhances visibility of it in darkened conditions and applications such as confined space entry. The GasAlertMicro 5 may also be used in applications such as hazmat and homeland security, industrial hygiene, airlines, landfills, the oil and gas industry and also chemical plants.

Be assured that your BW multi gas detector will provide you with as much protection as possible. It’s robust and is ideal for tough environments due to its water-resistant, concussion-proof housing. It’s also very easy to use with raised buttons which can be pushed with gloves on.
