Testo 175 H1 Temperature & Humidity Data Logger

The Testo 175 H1 is a two-channel temperature and humidity data logger designed for long-term monitoring of HVAC environments, storage rooms and building spaces. Two external probe channels measure relative humidity and temperature simultaneously, with dew point calculated automatically — giving you the full picture of air conditions without a separate instrument.

An alarm function triggers when readings fall outside programmed limits, and data is downloaded via USB using Testo ComSoft software for compliance reporting. For temperature-only logging, see the Testo 175 T2. See all test and measurement instruments at HVAC Shop AU.
