testo 191-P1 – pressure data logger for the food industry

testo 191-P1 – highly efficient validation of pasteurization and sterilization processes. In food production, pasteurization and sterilization are key factors in extending the shelf life of food products. These processes place extremely high demands on the measurement technology used. Our reliable and robust HACCP pressure data logger helps you meet these requirements effectively.

This is what the HACCP pressure logger testo 191-P1 offers:

  • High accuracy: HACCP pressure logger for monitoring absolute pressure with a measurement memory of 60,000 measurements.
  • Small and flexible design: with a diameter of 20 mm, the logger is ideal for use in confined spaces and small objects.
  • Robust and durable: high quality materials and innovative design make the HACCP logger particularly robust and durable. With hermetically sealed measurement technology in a separate stainless steel housing, the HACCP logger impresses with its reliability and robustness.
  • Battery change in seconds: the battery cover is threaded and can be quickly and securely screwed onto the HACCP logger without tools.
  • Reliable and tight: the data logger remains 100% tight even after a battery change. The battery cover is coated with high temperature resistant polyester ether ketone (PEEK).
  • Flexible height: the size of the logger can be varied using two different battery types. The small battery significantly reduces the dimensions of the logger. The larger battery (included in the delivery) is suitable for measurements at low temperatures, e.g. in freezing facilities.

Programming, reading and analysis of the data logger

Very practical to use: in addition to storing the data loggers, the multifunction case (available in two different sizes) can also be used for parallel programming and reading of up to 8 data loggers simultaneously. This means you don’t need an extra reading device and you also save time. With the specially developed testo 191 software (order separately), you can program and read out the data logger, as well as analyze the measurement data on the computer.

The clear program structure guides you intuitively through the process step by step. During entry, it provides assistance at critical points through warnings. The software enables even inexperienced users to easily perform the measurement process.
