Review on 📊 CEM Accurate PM2.5 Multifunctional Recording Tester by Hesham Peltier

Comparing the PM2.5/PM10 readings with another similar device I own and this device gave accurate readings. The readings seem to update within seconds. There are several different variants of this device, with some of the variants able to measure TVOC and CO2, notably the DT-968 only measures PM2.5/PM10 concentrations. The best thing about this device is the large and easy-to-read display. ideal for determining at a glance if you need to turn on an air purifier. The device has an automatic power off to protect the battery when not connected. Battery life isn't fantastic, so this is a useful feature. If you don't need a large, easy-to-read display, you can probably find cheaper options.
