191-P1 - HACCP pressure data logger

The testo 191-P1 HACCP pressure data logger is certified by HACCP International for use in food production environments and is engineered for efficient monitoring of absolute pressure during pasteurization and sterilization process validation. Measuring absolute pressure across a range of 1 mbar to 4 bar, the 191-P1 is ideally suited for saturated steam pressure verification in retorts and pasteurizers - enabling technicians to confirm that specified steam pressure conditions are maintained throughout the thermal processing cycle for complete lethality documentation. The robust, reliably sealed housing maintains IP integrity after battery changes using the quick-screw battery block, which enables replacement in seconds without tools. Multiple 191-P1 loggers can be simultaneously programmed and downloaded via the testo 190 multifunction case. Compatible with testo 191 professional software for HACCP-compliant pressure validation reporting.
