This is an instruction manual for an instrument to measure wind speed, wind direction, temperature, and humidity.
The testo 410-2 is a measuring instrument designed to measure air speed, humidity, and temperature. It is typically used to measure air speed at ventilation outlets, but can also analyze climatic conditions by simultaneously measuring humidity and temperature. The device features a plastic impeller, a Testo humidity sensor, and an NTC temperature sensor. This manual is written in German.
