Overview
A single-channel thermocouple data logger to measure and record temperature in indoor environments. Designed for a broad range of monitoring applications - from industrial process monitoring to concrete maturity testing - this logger provides exceptional flexibility by accepting J, K, T, E, R, S, B or N type thermocouple probes (sold separately).
Onset also offers a four-channel thermocouple data logger, the HOBO UX120-014M.
Features
- High-accuracy J, K, T, E, R, S, B, N thermocouple readings
- Easy-to-view LCD display
- Large memory capacity
- Visual high & low alarm thresholds
- Burst and Statistics logging modes
- Record ambient temperature with internal thermistor
