DM126-O3 Handheld O3 Meter Detector USB Powered Air Quality Monitor

The DM126-O3 is a handheld O3 meter detector for monitoring ozone concentration in the air. It uses an electrochemical O3 sensor with a 0-50ppm range and 0.01ppm accuracy, plus built-in temperature and humidity sensors and an on-board fan that draws in surrounding air for real-time readings. The 3.5in colour LCD is easy to view. It is USB powered and charged via the USB port, running on a built-in 2000mAh rechargeable lithium battery, and it warns when the battery is low. A user-adjustable O3 alarm threshold sounds when the set level is reached.
