Delivery terms
Return policy
Scope of delivery: temperature and humidity data logger testo 175 H1 with external humidity sensor (NTC / capacitive humidity sensor), wall holder, batteries and factory calibration protocol.
With a long-term stable humidity sensor, the testo 175-H1 is the professional temperature and relative humidity data logger. The external probe has a faster response time compared to the sensors installed inside the housing. The testo 175-H1 constantly monitors the temperature, humidity and dew point value and shows them on the display.
The measurement data can be read on a PC either via a USB cable or via an (optionally available) SD card.
