Measuring -58 to 284°F to ±0.18°F on a flexible 30.5" (775 mm) probe, this data logger reaches measuring points rigid probes cannot. In addition, HACCP International certification supports audit documentation for food safety programs. Sealed stainless steel and PEEK construction carries an IP68 rating.

Qualifying a thermal process means placing a sensor exactly where the process is hardest to reach. This T3 logger carries a flexible probe 30.5" (775 mm) long, measuring -58 to 284°F (-50 to 140°C) with an accuracy of ±0.18°F (±0.1°C) over most of that span.
Built for the chamber, not the bench
Hermetically sealed measuring technology sits in a stainless steel and PEEK housing rated IP68, so the logger survives repeated wet, pressurized and sub-zero cycles. At 0.79" (20 mm) across it fits recesses, packed loads and container necks that larger instruments cannot enter.
Battery changes in seconds
The threaded battery screws on by hand and changes without tools, and the logger remains fully sealed afterwards. Data is read out through the multifunction case, which programs and downloads up to eight loggers at once using testo 191 professional software for HACCP-ready documentation.
