Hot Wire Anemometer ThermoAir3
Hot Wire Anemometer for measuring very low air flow / flow meter for industry / flow from 0.01 m/s / with directional or omnidirectional sensor

The hot wire anemometer ThermoAir3 specialises in measurements of very low air flows and determinations of turbulence grades. The humidity can also be determined with the separate humidity sensor. Automatic temperature compensation, barometric altitude correction, simple zero point alignment, individually determined sensor guarantees highly precise measurements. The Hot wire anemometer is easy to handle. It also has exchangeable sensors for flow, temperature and humidity, automatic zero point, calibration compensation from 0 … 40°C and measurement of turbulence grades. Low flow measurements in laboratories, clean rooms, air conditioning, drying and cooling systems as well as convenience and comfort measurements in the workplace are the typical applications for this instrument.. Here you can find an overview of all hot wire anemometers. If you have any questions about the wind velocity meter KM series, see the following technical specification or contact us: + 44 (0) 2380 98703 0. Our technicians and engineers will gladly advise you on all anemometers and all products in the field of regulation and control, measuring instruments and scales.
