Delivery Scope

testo 176 P1, 5-channel pressure data logger with internal pressure sensor (absolute pressure) and external probe connections (NTC/ capacitive humidity sensor). Including wall bracket, battery and calibration protocol

Absolute Pressure, Humidity and Temperature Data Logger - testo 176-P1.
Model No: testo 176-P1. Part No: 0572 1767.

When ambient conditions, for example in a laboratory, need to be documented securely and highly accurately, the testo 176 P1 is the right data logger. It has an integrated absolute pressure sensor and connection possibilities for two external temperature/humidity probes (optional)

  1. Continuous measurement and documentation of absolute pressure
  2. Two optionally connectable probes for humidity and temperature values
  3. Large measurement data memory for up to 2 million measurement values
  4. Software for data evaluation on a PC


Delivery Scope

testo 190-P1 x 1 CFR data logger, including battery large, calibration protocol and instruction manual

Pressure (CFR) Data Logger - testo 190-P1
Model No: testo 190-P1 Part No: 0572 1900

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

  1. Durable, robust, reliably tight, even after changing the battery
  2. Changing the battery takes just seconds, saving time and increasing efficiency
  3. High-precision monitoring of absolute pressure in the 1 mbar to 4 barabs range
  4. Simultaneous programming and readout of several CFR data loggers via the multifunction case


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

  1. High-precision: precise CFR data logger for monitoring the absolute pressure with reading memory of 60,000 readings
  2. 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
  3. 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
  4. 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
  5. 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)
  6. 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.
