Description
Overview
GAOTek wireless air quality tester is not an air pollutant, but it can still have a negative effect on us when levels are too high. When levels rise, we tend to get sleepy and have trouble focusing, and some people even develop headaches. For this reason, it is important for occupants to have CO2 monitor to stay at a healthy level.
Features
- It is a desktop and wall mountable instrument
- It measures CO2 concentration in air
- Displays the real-time value of CO2 concentration in ppm
- Displays temperature and relative humidity
- The measured CO2 value in ppm will be displayed on the LCD
- Programmable alarm setting by users
- It has 1500 mAh backup rechargeable battery
- Powered by USB, or optional AC adapter, or battery
