Description
CFR temperature logger testo 190-T2: Qualification of Sterilization and Lyophilization Processes
The reliable and robust testo 190-T2 CFR temperature logger helps effectively meet the stringent requirements for the qualification and validation of sterilization and freeze-drying (lyophilization) processes in the pharmaceutical industry.
Advantages and Design Features of the testo 190-T2 CFR Logger
- High Accuracy: The logger has a memory capacity of 60,000 measured values.
- Probe: Equipped with a long rigid probe (length 115 mm, Ø 3 mm).
- Compactness: The slim diameter of the logger (20 mm) allows it to be used in confined spaces, such as in bottles and cans.
- Robustness and Reliability: The measuring ‘core’ is encased in a separate stainless steel housing, reliably protecting it from external influences.
- Instant Battery Replacement: The battery can be replaced quickly and safely without special tools thanks to the screw-in design.
- Hermetic Sealing: The logger remains completely hermetically sealed even after battery replacement. The battery housing is covered with temperature-resistant PEEK (Polyetheretherketone).
- 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 (e.g., in freezing systems).
Programming, Readout, and Data Analysis
- Multi-functional Case: The case (ordered separately) is used for storage, as well as for the simultaneous programming and readout of up to 8 loggers, which saves time.
- 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.
