Description
The 56-TR-52I is TandD’s compact single-channel logger for temperature with an external probe on cable — featuring the same robust design as the 56-TR-51I but with the probe separated from the electronics, allowing you to measure in locations where the logger unit does not fit or would be damaged. The measuring range extends from -60 to +155 °C, depending on the probe used.
A standard probe is included. Powered by an LS14250 lithium cell for approximately 4 years. Data retrieval requires the communication holder 56-TR-50U2 (sold separately) — optical data transfer eliminates the risk of short circuits caused by wet contacts.
Features
- External thermistor probe on cable (included)
- Measuring range -60 to +155 °C (probe-dependent)
- Fast response time: approx. 80 seconds in air, approx. 7 seconds in stirred water
- Accuracy ±0.3 °C (-20 to 80 °C), ±0.5 °C / ±1.0 °C in extreme ranges
- IP64 splash protection on the logger unit
- 4-year battery life on a single LS14250
- 16,000 data points
- 15 fixed logging intervals (1 second to 60 minutes)
- Built-in LCD and alarm LED
- Optical communication via 56-TR-50U2

Applications
The 56-TR-52I is suitable for applications where you need to measure outside the -40/+80 °C range or need to place the probe at a specific point. Typical applications: ovens, freezers with the probe placed inside the product itself, heating circuits, autoclaves. For the modern Bluetooth version, see 56-TR42A. For a built-in probe instead, see 56-TR-51I.
