Anemometers are manual induction
The vane testo 417 anemometer is intended for the speed of air and calculation of a volume expense.
The big krylchatka with a diameter of 100 mm who is used for measurement of total value of speed near ventilating grates is built in the device.
For the most exact measurements it is necessary to apply a funnel to measurements of a volume expense.
Additional benefit of testo 417 anemometers is the built-in sensor for measurement of air temperature.
Control of air temperature allows to define efficiency of heating or cooling of air indoors.
The testo 417 anemometer is the reliable assistant for experts who are engaged in commissioning, control and service of central airs and a supply and exhaust ventilation in inhabited office and industrial rooms.
