testo 190-P1 - CFR Pressure data logger

Order-Nr.  0572 1900

  • High-precision monitoring of absolute pressure in the 1 mbar to 4 barabs range

  • 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 CFR data loggers via the multifunction case

Use the testo 190-P1 CFR pressure data logger for efficient monitoring of sterilization and freeze-drying processes. Designed for the pharmaceutical industry, the testo 190-P1 CFR data logger is ideally suited for tightness or overpressure testing in autoclaves and freeze-drying systems.


Product Description

The qualification and validation of sterilization and freeze-drying processes is subject to high requirements and is a key element of quality assurance in the pharmaceutical industry.

Our reliable and robust CFR pressure data logger supports you in meeting these requirements efficiently.

This is what the testo 190-P1 CFR pressure data logger offers

  • High-precision: precise CFR data logger for monitoring the absolute pressure with reading memory of 60,000 readings
  • Small and slim design: with a diameter of 20 mm, the data loggers are ideal for use in tight objects or cramped conditions – e.g. in the recesses of freeze-drying systems
  • Robust and durable: high-quality materials and innovative construction make the CFR data logger particularly robust and durable. Thanks to hermetically sealed measuring technology in a separate stainless steel housing, the CFR 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 CFR data logger and changed intuitively and securely without using any tools
  • Reliably tight: the CFR 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 CFR 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 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 21 CFR Part 11-compliant testo 190 CFR 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. This means even inexperienced operators can use the software without any problem. The software thus enables even inexperienced users to carry out the measurement process easily.
