The HOBO U12 J, K, S, T Thermocouple data logger provides exceptional measurement flexibility by accepting J, K, S, or T thermocouple probes. An internal thermistor monitors and records ambient temperature for cold-junction compensation, for maximum accuracy.

Features:

High-accuracy J, K, S, T thermocouple recordings
Automatic cold-junction compensation
Accepts subminiature thermocouple connectors
Direct USB interface

Environment:

The U12-014 Data Logger is for use in Indoor environments
