Ideal for temperature monitoring in sterilization applications, in liquids or on surfaces, for example on plates in freeze-drying systems. Designed for the pharmaceutical industry, the testo 190-T3 CFR temperature data logger for sterilization and freeze-drying processes has a long, flexible probe which also enables you to measure in corners.

Designed for the pharmaceutical industry, the testo 190-T4 CFR temperature data logger for sterilization and freeze-drying processes has two long, flexible probes which also enable you to measure in corners. It is particularly suitable for monitoring the temperature in autoclaves, containers, liquids or on surfaces, for example on plates in freeze-drying systems.

Certified by HACCP International, the testo 191-T3 temperature data logger is ideal for monitoring the temperature in liquids or on surfaces, such as on plates of freeze-drying systems. Use the data logger designed for food production for monitoring pasteurization, sterilization and freeze-drying processes.

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.

The probe holder ensures precise measurement of the surface temperature in a freeze-drying system. To do this, secure the data logger's flexible temperature probe in the slot of the probe holder. The weight of the probe holder ensures that the temperature probe is in direct contact with the surface.
