BW Clip (2 Year) Hydrogen Sulphide (H2S) 5/10 Ppm Gas Detector


Learn More

This particular version of the BW Clip from BW Technologies is a single gas detector designed for monitoring Hydrogen Sulphide (H2S). It has alarm set points of 5/10 ppm and comes with a 2 year warranty (from activation).

Use this BW gas detector in hazardous situations and industrial applications to assist you with your safety and compliance. It’s an extremely robust H2S gas detector with a concussion-proof, water-resistant housing. It comes in a brightly visible yellow colour, which is ideal for low-light conditions.

Despite being a robust instrument the BW Clip is extremely light in weight and is compact, ensuring it can be easily worn on clothing and won’t interfere with your daily work duties.

The BW Clip has many additional advantages. There’s no need for calibration during its 2 year lifetime, as well as no need for a battery or sensor change or battery charging. It will run continuously with no downtime and also log 35 of the most recent gas events and bump test results. This ensures there’s always a record of the main events during its use.
