CFR Temperature Logger testo 190-T3: Qualification of Processes in the Pharmaceutical Industry
The reliable and robust testo 190-T3 CFR temperature logger helps effectively meet the stringent requirements for the qualification and validation of **sterilization** and **freeze-drying (lyophilization)** processes, which are a key element of quality assurance in the pharmaceutical industry.
Advantages and Design Features of the testo 190-T3 CFR Logger
- High Accuracy: Memory capacity of 60,000 measured values.
- Probe: Long flexible probe (length **775 mm, Ø 1.5 mm**) – ideal for sterilization processes and measuring surface temperature in lyophilization systems (in combination with a probe fixture, ordered separately).
- Compactness: The slim diameter of the logger (**20 mm**) allows it to be used in confined spaces.
- Robustness and Reliability: The logger is exceptionally robust thanks to high-quality materials and an innovative design. The measuring ‘core’ is reliably protected by a separate stainless steel housing.
- Hermetic Sealing: The logger remains completely hermetically sealed even after battery replacement. The battery housing is covered with temperature-resistant PEEK (Polyetheretherketone).
- Battery Replacement: The battery can be replaced quickly and safely without special tools thanks to the screw-in design.
- Variable Height (Batteries): The size of the logger can be changed depending on the use of one of two battery types. The small battery makes the logger very compact. 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 (available in two sizes, ordered separately) is used not only for storage but also for the simultaneous programming and readout of up to 8 loggers. This saves time and eliminates 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 helps to carry out the process step-by-step, allowing even inexperienced operators to use it without problems.
