Portable Gas Detector, Gas Clip 4 Gas Monitor Meter Tester Analyzer, Rechargeable LCD Display Sound Light Shock Air Quality Tester, 2 Year Detector…

We needed a carbon monoxide detector for a coal furnace and it worked perfectly! Just turned it on and it was already calibrated and ready to detect it. It alarmed when the levels started going up ( I test it near the fire) and it stoped when the levels of CO dropped. Excellent!!!!

My husband is Safety Manager for a mid size oil and gas company. They have many drilling sites. They are using these on every pad. I believe the company has purchased maybe 35 SO FAR!! Thanks for the product. ETA BATTERIES ARE NOT KEEPING A CHARGE. WON'T ORDER ANYMORE.

I bought this is 2021. Maybe they programmed it to stop working after a while? Maybe the oxygen sensor degrades over time? In any case, over 100$ spent and the thing is useless. All four values read 0 ppm or 0.0%. I have charged, restarted, tried every setting in the settings. I can set the alarm for low oxygen to 0.1% but since it consistently reads 0.0%, the alarm keeps going. Cannot be muted, which is probably a safety feature, but when the alarm is faulty, and you cannot override it, it is really annoying. While trying to troubleshot it, I found the alarm mutes after something like 10 minutes. Switching off then on again, the audio comes back on. I would rather have the alarm serviced than just throw it out, but how to do that? In either case, it worked when I bought it, but now that I need it, it stopped working. No, I would not recommend buying this unit.

Gave clear warning when in a confined area with too many people with inadequate ventilation. Gave loud clear alert when O2 levels dropped below save levels. Works great in confined spaces due to Covid.

Here, I fixed the annoying screaming japanese woman from scaring my dog. I cut the back out with a saw because I couldn't get the screws out. Then I cut the speaker & wire drivers out with an Exacto knife. The photo is the back of the unit, Sans Speaker.

Just as good as a Mini Rae for a lot less money. Just as accurate. Better battery life/ operational time per charge. A little less durable. For the price difference I can get five of these. I'd rather have 5 guy's around a site with these than just one with a Mini Rae.

It’s good. I like it. When I ordered, however, I wasn’t given ANY delivery hope/expectation information. No tracking, just a note they will email me when it ships. I waited about a month and just before I gave up to request a refund, it shipped. It’s a good product, but it’s worth the extra money to buy local if you want some kind of clue when you’ll see your product.

I used this monitor in the field and when notable brands were measuring 5ppm H2S, this unit happily read 0 ppm. Failed H2S bump test after. I kept this unit in the foam lined when not in use and always with charge.
