191-T4 - HACCP temperature data logger with two long, flexible probes

The testo 191-T4 HACCP temperature data logger, certified by HACCP International, is equipped with two long, semi-flexible temperature probes for simultaneous dual-point temperature monitoring in food production pasteurization, sterilization, and freeze-drying validation processes. The dual-probe capability is specifically valuable for heat penetration analysis - enabling simultaneous measurement at both the surface and core of a food product to characterize thermal treatment uniformity and validate that lethal temperature conditions have been achieved throughout. Each flexible probe can navigate into corners, wrapped product, and complex load geometries within process equipment. Sealed housing with quick-screw battery replacement maintains integrity throughout demanding process environments. Multiple 191-T4 loggers can be simultaneously managed via the testo 190 multifunction case. Compatible with testo 191 professional software for comprehensive HACCP validation documentation.
