TopTes Guard-101 Gas Detector, 4 Gas Monitor for H2S, CO, LEL and O2, with Vibration, Visual and Audible Alarms, 14h Long Battery Life, Safety Explosion-Proof, for Work, Home - Orange

Seems pretty accurate always nice to have when you’re using the propane heater in a tent or enclosed space being able to tell your oxygen levels and carbon monoxide gives you a little bit more of reassurance that you’re not gonna just wake up dead

I kept smelling gas at my Grandmother's house. I could smell it but Grammie couldnt. I called the gas company because this gas meter kept alarming. The gas company's detector wasn't picking up the gas and the gas technician couldn't smell it either. I kept insisting there was gas. This gas meter helped me convince the gas technician to keep searching for the leak. He finally found it and Grammie's house didnt blow up. Very thankful!

Part of my job is training new individuals for confined space. New individuals are often unsure of what they are doing. I wanted an air monitor that would work but also be expendible if the trainee would drop it or it would get misplaced in traveling to and from locations. I compared this unit to my name brand ones costing 5 to 10 times more expensive. Its actually significantly more accurate than i would have expected. I would actually reccomend this unit. Its a great value for a first air monitor. It was very easy to used and battery last forever.

Buen producto en relación con el costo

If you work in the oil fuels or any part of Texas, where there’s oil and natural gas this will save your life in more ways that you’ll ever know

I bought two of these. I only used it once or twice and now they O2 Alarm is going off like crazy. In order to get it to turn off, I have to adjust the zero by 10%. This isn't right. If I shoot CO has to it, it doesn't respond. It doesn't seem to have any type of pup that sucks air in. I tried researching what could be causing it but no luck. Pretty disappointed.

It works perfectly and the battery lasts a long time

Works perfect at a great price
