Measuring -58 to 284°F to ±0.18°F on a rigid 0.98" (25 mm) probe, this data logger validates autoclave and steam sterilization cycles. In addition, a 0.79" (20 mm) body reaches recesses and packed load positions larger instruments cannot. Sealed stainless steel and PEEK construction carries an IP68 rating, and 60,000 readings cover long qualification runs.

Qualifying a thermal process means placing a sensor exactly where the process is hardest to reach. This T1 logger carries a rigid probe 0.98" (25 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 190 CFR software for 21 CFR Part 11-ready documentation.
