•Two long, flexible probes for precise temperature measurement in liquids and on surfaces and for the analysis of heat penetration •Durable, robust, reliably tight, even after changing the battery •Changing the battery takes just seconds, saving time and increasing efficiency •Simultaneous programming and readout of several HACCP data loggers via the multifunction case Certified by HACCP International, the testo 191-T4 temperature data logger for monitoring pasteurization, sterilization and freeze-drying processes has two long, semi-flexible probes which allow you to measure in corners as well. The data logger is designed for food production and is particularly suitable for monitoring the temperature in liquids or on surfaces, for example on plates of freeze-drying systems. Product Description Pasteurization, sterilization and freeze-drying are key processes in food production when it comes to increasing the shelf life of foods. These processes place extremely high demands on the measuring technology used. Our reliable and robust temperature HACCP data logger supports you in monitoring these processes efficiently. This is what the testo 191-T4 HACCP temperature data logger offers •High-precision: precise HACCP data logger with two long, flexible probes (length 775 mm, Ø 1.5 mm), reading memory of 30,000 readings per channel •Two long, flexible probes: ideal for sterilization applications in liquids or on surfaces of freeze-drying systems. In combination with the freeze dryer probe holder (please order separately), the surface temperature of freeze-drying systems can be accurately measured
