High-Precision Handheld Carbon Monoxide Meter | Portable CO Detector | CO Gas Leak Detector and Monitor Tester (1000ppm) Review

Bought because our alarm went off and we wanted to check if the alarm was broken. The precision seems to be right and does what it should.

It takes about a minute to calibrate after power on, but then works fine. The first time I turned on the temperature it was inaccurate but okay there

My device was actually encrypted in Chinese; we only read english here in our family in ohio, usa. I returned the device the next day, because of the Corona19 pandemic, customs kept the return package for several weeks. The seller showed decency and reimbursed the cost of the devices.

Junk. There was a poorly ventilated water heater spewing CO2 everywhere. Bought a gauge to make sure the pull inductor completely fixed the problem. Here's a picture of a counter showing zero right next to the erroneous wh. To say the counter is inaccurate is to say nothing. No value for my money.

I bought this to check my car for a possible CO leak. The meter is incredibly sensitive to heat and gave me readings on all the charts. I eventually determined that there was no exhaust leak in my car, but the incorrect meter reading caused me a lot of unnecessary stress in the process. Save your money, don't buy this junk!

I thought I bought the Anpiggy brand even though it was around $56. When I received it, it was the "Smart Sensor" brand. that's $20 cheaper. I mean I get it it's the same product but I thought maybe spend $20 more and maybe get something more accurate and reliable. But I have no idea. That's what I ended up with. Don't order here, just buy a smart sensor and save $20 or pay an extra $50 and get a better one.

I compared this device to my colleague's $300 device made by Forensics. The cars I work on are often checked for carbon monoxide leaks, and I happened to find one that had a fairly large leak. I put both gauges in the car and watched from the outside while we warmed up the engine and both gauges read the same thing after 20 minutes, but this little cheap gauge responded MUCH faster than the more expensive forensic gauge! I don't know how reliable it is. will change over time and unless I'm in…

I have never had a portable air tester. I had an odor in my home that I thought might be due to my central air filter not being changed in a long time due to pandemic restrictions, so I called the HVAC company to have the filter replaced. The guy who showed up was testing my rooftop HVAC unit after hanging something similar to this test unit, orange and black, on one of my room's air vents. The device emitted a continuous tone. The device hanging in the room next to the ventilation began to…
