The compact Uni-T A37 is a practical indoor air quality meter that shows CO2, temperature, humidity, and time on a clear LCD. Thanks to an NDIR sensor and automatic calibration, it delivers stable measurements and, when the set level is exceeded, triggers a sound and visual alarm for a quick response.
The Uni-T A37 CO2 meter helps maintain a healthier environment at home, in the office, and at school. It immediately alerts you to deteriorating air quality caused by increased CO2 concentration and makes it easier to decide when you need to ventilate. The clear display also shows temperature, humidity, and time, so you always have key information in view.
Reliability is ensured by NDIR CO2 measurement technology together with automatic calibration. For everyday convenience, it features backlighting, a low-battery indicator, and automatic power-off.
