🔥 Advanced Fast & Low Level CO Detector: Display > 10ppm, 25ppm Buzzer Trigger Review

Actually better than any other CO alarm I could find. I bought this to replace another brand that seemed to still work but was no longer alarming when tested. As I was considering purchasing, I learned that most CO detectors will not alarm until the CO level reaches 100ppm and will remain at that level for a long time, often failing to report lower CO levels even if they are above have a digital display. These forensic detectors will alarm at 25ppm for 1 minute and display readings below 10ppm.

The clear front cover was scratched at the factory (rather than shipping). The button is hard enough to press to reset/check etc. I wish there was a way for me to do a real level test. If you have a gas oven I would buy a low oven and spend the money. The kiddie I bought was rubbish. On the plus side, I held it 2 feet from the exhaust pipe in a closed garage and it started to rise and sting. It reached 145ppm before I stopped the test.

There was nobody inside, but we installed two carbon monoxide detectors and several cameras. Designed for low CO levels, this device quickly alerted us and we were impressed. The other standard smoke/carbon monoxide unit did…
