Thermoelectric Anemometer

The ThermoAir3 is suited for measuring small flow ranges of gaseous media. With a separated humidity probe it can also detect the relative humidity. Highest precision is achieved by the integrated temperature compensation, the barometric altitude correction, the automatic zero point calibration and the individual calibration in our wind tunnel (belonging to our accreditation according to ISO 17025).
