Overview of Thermoelectirc Anemometer | ThermoAir3

The ThermoAir3 is a specialist instruments for measuring very small air flow and determining degree of turbulence, as well as  Relative humidity sensor for humidity measurement.  Includes  automatic temperature compensation, barometric pressure correction for local altitude, simple zero adjustment, individually adapted measuring sensor and our SCS wind tunnel guarantee high precision measurement and simple handling.

Typical applications for this instrument are very small flow rate measurements in the lab, in clean room, air conditioning, drying and refrigeration installation, plus workplace comfort and well-being measurement.

Features of ThermoAir 3 Thermoelectric Anemometer

  • Flow from 0,015 m/s
  • Automatic temperature compensation
  • Multi-sensor anemometer for flow and humidity measurements
  • 100% guaranteed measuring tolerance
