Part No. AQH-20 | CO₂ Range: 0-2000 ppm, ±30 ppm ±5% rdg

Indoor air quality assessments often require separate readings for CO₂, temperature, and humidity. The Dwyer AQH-20 combines all three measurements on one backlit LCD, giving contractors a convenient solution for building inspections and ventilation surveys.

The meter uses non-dispersive infrared sensing to measure CO₂ across a 0-2000 ppm range with ±30 ppm ±5% of reading accuracy. Temperature measurement covers 14-140°F, while relative humidity is measured from 0.0-99.9% RH.

Customizable alarms can alert users when selected indoor air quality conditions require attention. Response times are under 30 seconds for CO₂, under 2 minutes for temperature, and under 10 minutes for humidity.

The AQH-20 is powered by four AA batteries, which are included, and comes with a carrying case for convenient site use.
