Testo · Adaptateur de distance court
Distance adapter short
The distance adapter is used to fix the data logger securely in the programming and readout unit. This enables reliable programming and readout of the logger.

Testo · testo 191-T4
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.

Testo · Grande pile
The battery for data loggers takes just seconds to install, because it fits perfectly when screwed into the logger. This means you do not need to worry about any damage to the data logger as a result of fitting the battery.

Testo · Mallette multifonctions, petit modèle
One case – numerous functions: This case not only enables secure storage and transport of the data loggers. It can also be used to program and read out 8 data loggers simultaneously.

Testo · Support de sonde pour lyophilisation (puck)
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.

Testo · testo 191 Logiciel Professional v1.4
Use the intuitive testo 191 professional software to programme, read out and analyze your HACCP data loggers quickly and easily.

Testo · Enregistreur de données IAQ pour les mesures de longue durée
For long-term monitoring of the indoor air quality: Use the IAQ data logger as a stand-alone measuring unit for carrying out long-term measurements with the testo 400 IAQ measuring instrument. While the stand-alone data logger is carrying out the IAQ measurement, you can use the IAQ measuring instrument for measurements elsewhere.
