The measuring instrument for ambient air conditions, for assessing Indoor Air Quality and adjusting and inspecting VAC systems. testo 435-1 is an affordable introduction to measurement engineering for ambient air conditions. The IAQ probe measures Indoor Air Quality by measuring CO2 level, air moisture and air temperature. Temperature and humidity measurement is integrated in the thermal probe. In addition, it is also possible to connect additional temperature probes. Readings from up to 3 temperature probes can be displayed in the clearly laid-out measuring instrument display; data transmission is radio-controlled, therefore wireless. Measurement data is printed on site on the Testo printer.
