Accurate, great safety product, recommended for heaters for in enclosures
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

Low cost monitor but actually not too bad
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.

Saved Granmmie's life!
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!

Not with the risk to save a few extra bucks
This product was ordered then returned for a replacement because the oxygen level was at 0% and alarming. I tried to reset multiple times read through troubleshooting and determined it was deffective. The replacement I received was the same problem only the oxygen level was reading 18.0%. I run a commercial pressure washing and epoxy company and most of our work is in confined spaces. I cannot afford to risk my employees lives due to a faulty LEL. I won't use language to make this company look bad but I will say that after hiring for growing contracts it's a shame for this company because not only do I monitor the air from above these vault's but everyone will have an LEL attached to their harness which means the 7 LEL's I purchased could have been through them had these functioned correctly. I'm definately glad i only purchased 1 to try it out first. I Will say the return was easy for a full refund so at least they have that going for them.

Voilà plusieurs fois que je l'utilise en exploration sousterraine de carrières et mines abandonnées. Il semble précis et très pratique et n'a rien a envier à des alternatives plus "pro" et onéreuses que j'ai pu également tester. Cependant hormis pour l'O2, je n'ai pas encore pu tester les autres capteurs.

solocitamos la certificacion de los detectores y no la pueden dar. Tuvimos que hacer esta certificacion con un gtercero, con muchas limitantes, porque no se puede ingresar al sistema del equipo, dique por "Porteccion"
