    testo 191-T4 - HACCP temperature data logger with two long, flexible probes

    0572 1914
  1. Two long, flexible probes for precise temperature measurement in liquids and on surfaces and for the analysis of heat penetration
  2. Durable, robust, reliably tight, even after changing the battery
  3. Changing the battery takes just seconds, saving time and increasing efficiency
  4. Simultaneous programming and readout of several HACCP data loggers via the multifunction case
    5. 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.
    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
    • Slim design: with a diameter of 20 mm, the loggers are ideal for use in tight objects or cramped conditions
    • Robust and durable: high-quality materials and innovative construction make the HACCP data logger particularly robust and durable. Thanks to hermetically sealed measuring technology in a separate stainless steel housing, the HACCP data logger impresses due to its reliability and maximum robustness
    • Battery change in seconds: the practical thread enables the battery to be screwed onto the HACCP data logger and changed intuitively and securely without using any tools
    • Reliably tight: the HACCP data logger remains 100% tight even after the batteries are changed. The battery housing is coated in highly temperature-proof polyether ether ketone (PEEK)
    • Flexible height: the size of the HACCP data logger can vary with two different types of battery. The small battery makes the logger's dimensions particularly compact. The larger battery (included in the scope of delivery) is suitable for measurements at low temperatures, for example in freezer systems

     

    Programming, readout and analysis of the data logger

    Very practical to use: in addition to being used for storage, the multifunction case (available in two different sizes) can also be used for parallel programming and readout of up to 8 data loggers simultaneously. This means you do not need any additional readout unit and you also save time.

    With the specially developed testo 191 professional software (please order separately) you can program and read out the data logger, as well as analyzing the measurement data, on the PC. The clear software structure guides you intuitively through the process step by step. During input, it provides help at critical points through warnings. The software thus enables even inexperienced users to carry out the measurement process easily.

    1 x testo 191-T4 HACCP data logger, including battery large, distance adapter long for testo 191 programming and readout unit, thread extension, calibration protocol and instruction manual.
