Our hand-held measurement instruments are built with field HVAC engineers and operators in mind. Designed for speed, reliability and portability, they cover the majority of air-quality parameters typically found in the HVAC sector: speed, temperature, humidity, airflow and lighting levels. What’s more, our instruments also detect gases and assess air quality.
