2 Year Hydrogen Sulfide GasAlertClip Extreme Gas Monitor

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

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.

We operate in the ND oil patch and are required to have H2S monitors. We've been using these for 3 years and haven't had any problems. We don't encounter a lot of H2S gas either. They are good for 24 months from activation.

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

The portable carbon dioxide is a great life savings device for firemen and auditors how are always in hazardous areas like around fire and boilers, this little device give me the satisfaction make me feel safe to be able to work comfortable very good product

If it ever fails to detect the H2S gas that it's supposed to detect, I won't be around to edit my review to 1 star. So until then, I give it 5 stars for protecting me.

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

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......
