Testo 175 T3 Dual Thermocouple Temperature Logger

The Testo 175 T3 is a two-channel thermocouple data logger designed for high-precision temperature monitoring across a wide measurement range. Two external thermocouple inputs accept Type K or Type J probes, covering temperatures from -200°C to +1000°C — making it suitable for HVAC, industrial and process monitoring applications where standard NTC loggers fall short.

The 175 T3 logs both channels simultaneously with an alarm function for out-of-range events, and data is downloaded via USB using Testo ComSoft software. For standard cold room and refrigeration monitoring, see the Testo 175 T2. See all test and measurement instruments at HVAC Shop AU.
