Product Overview

The TESTO 175-H1 is a 2-channel temperature and humidity data logger with external humidity sensor (NTC/capacitive humidity sensor). With its long term stable humidity sensor, the Testo 175 H1 is professional data logger for monitoring of temperature and relative humidity in work and storage rooms. The external probe (stump) stands out by providing faster reaction times in comparison to probes installed inside the housing. The free ComSoft basic software allows fast programming of data logger as well as easy data analysis. The Testo 175 H1 continuously records temperature and humidity values and in addition to temperature and humidity also shows dewpoint in the display if required. The indoor climate is thus monitored, emphasizing the need for targeted ventilation and air exchange.
