Review on 🔬 Ubrand Handheld Carbon Monoxide Meter with LCD Display - High Precision CO Gas Analyzer, Portable Leak Detector for Home Safety, 0-1000 ppm Range by Adam Jauregui

Used to test if a small gas generator can be vented from the garage to the street. All pipe extensions were very well sealed from the muffler and back pressure was minimal. However, CO accumulated rapidly. I cannot report on the ACCURACY of digital scales as they report data that can only be verified in a laboratory setting. Tests on a gas instantaneous water heater when heating and similarly on a gas oven showed only a negligible amount of CO, so it makes sense to have it in addition to our CO and fire detectors. A NOTICE. When you turn on this device for the first time, it takes some time before it is ready to use. This is described in the documentation and there is a counter on the screen.
