Review on 🌡️ GZAIR Temperature Relative Mountable 0-5000ppm Test, Measure & Inspect: A Comprehensive Solution by Eduardo Reyes

Great little device. The battery lasts all day, never empty. The readings are very stable and it has some great presets. Data logging schedules are also good. But be careful with that. After about a month of use, I accidentally dropped mine and the LCD cracked. It's useless now 😭😭 I had it in a small bag and used it many times during the development of my CO2-COVID tracker app, but it has a very delicate LCD. So be careful with it!
