BW TechnologiesGA24XT-H GasAlertClip Extreme 2-Year Detector, H2S, 0-100 ppm Measuring Range, 10 to 15 ppm Alarm Setpoint

A good price and it works as advertised.

I ordered 2 monitors and only one of them works. When tested one of them will not display a high alarm even with 25ppm being pumped into it. I tried to contact customer support and was told it could not be returned or refunded and it’s only been 21 days since I purchased them. These are life or death devices don’t risk it spend the money from a reputable vender.

Ordered these for the fire department chiefs. Small and portable means they are always with them anytime they enter a scene. They work GREAT.

Will not work with bw calibrator is not recognized, will only do self check, need to order different model if required to calibrate you unit

This is a good product. They are simple to use, very durable, Have used the BW detector in the past. Have not put the new ones in service yet.

Like this product, I use for on the well pads to detect H2S

Works

calibrates itself every 22 hours with a push of a button. alarm sounds at two different settings;low and high. monitor doesnt actually readout h2s levels, only alerts when it registers certain amounts. excellent monitor to use if you only need to know when h2s is present. not the monitor for you if you want to know an exact reading....such as 30ppm,37ppm,41pp, and so on......
