Description
CFR pressure data logger testo 190-P1: Qualification of Sterilization and Lyophilization Processes
The reliable and robust testo 190-P1 CFR pressure data logger is designed for effectively meeting the stringent requirements for the qualification and validation of **sterilization** and **freeze-drying (lyophilization)** processes in the pharmaceutical industry. It is used for monitoring absolute pressure.Advantages and Design Features of the testo 190-P1 CFR Logger
- High Accuracy: The data logger has a memory capacity of 60,000 measured values.
- Compact and Slim: The logger’s diameter is 20 mm, making it ideal for confined spaces, such as recesses in lyophilization systems.
- Robust and Reliable: The measuring ‘core’ is encased in a separate stainless steel housing, which ensures exceptional durability and protection against external influences.
- Instant Battery Replacement: Thanks to the screw-in design, the battery can be replaced quickly and safely without special tools.
- Hermetic Sealing: The logger remains completely hermetically sealed even after battery replacement. The battery housing is covered with temperature-resistant Polyetheretherketone (PEEK).
- Variable Height: The size of the logger can be changed depending on the use of one of **two battery types**. The large battery (included) is suitable for measuring low temperatures.
Programming, Readout, and Data Analysis
- Multi-functional Case: The case (available in two sizes, ordered separately) allows for the simultaneous programming and readout of up to 8 loggers, eliminating the need for an additional module.
- Specialized Software: The testo 190 CFR software (ordered separately) complies with **21 CFR Part 11** requirements.
- Software Convenience: The simple and clear software structure with notifications at critical points allows even inexperienced operators to use it without problems.
