Testo 191-T3 Professional HACCP Temperature Data Logger with Flexible Probe

The Testo 191-T3 HACCP temperature data logger is a highly precise, robust instrumentation node certified by HACCP International, specifically engineered for the qualification, validation, and process monitoring of food production assets. Operating with an ultra-accurate single-channel Pt1000 sensor module, this logger features an integrated 775 mm long, flexible probe (Ø 1.5 mm). This design makes it an elite choice for monitoring core temperatures in tight containers, liquids, or directly on the heating plates of freeze-drying systems. Built with high-grade stainless steel and a heat-resistant PEEK polymer housing, this slim device ensures absolute food safety and maximum structural reliability during pasteurization, sterilization, and freeze-drying processes under high pressure.

Industrial & Food Processing Applications

  • Food Pasteurization & Sterilization: Complete technical validation tracking inside active autoclaves, processing cookers, and closed lines using the long flexible line.
  • Freeze-Drying (Lyophilization) Controls: High-precision surface temperature mapping across system plates when combined with specialized freeze dryer probe holders.
  • Canned & Liquid Stock Diagnostics: Direct heat logging within high-density fluid vats, batch cooking vessels, and commercial vacuum packages.
