Indoor Air Quality, Comfort and HVAC

Testo 435 IAQ Meters
Testo 435 IAQ Meters

Testo 435 family of instruments can monitor and record critical Indoor Air Quality parameters using wired and wireless probes to monitor atmospheric CO2, air velocity, relative humidity (dew point), temperature, absolute pressure, differential pressure and illumination intensity. In its most sophisticated configuration the instrument system datalogs to a PC or connects via IrDA to a thermal printer for onsite data analysis.

This instrument is ideal for taking velocity in FPM (0 to 8,000 fpm), volumetric flow measurements in CFM (volume flow calculation 0 to 999,999 CFM) and temperature readings (-58.0 to 300.0 °F). The Testo 435 anemometer can average readings over time or at a number of positions and easily calculate volumetric flow in CFM, m3/sec, m3/hr, etc.

More than 10 different probes are available for use with the Testo 435 family of instruments.
