CFR data loggers

Highly efficient validation of your sterilisation and freeze-drying processes.

CFR data logger for process validation and qualification

The challenge: Validating sterilization, freeze-drying, cleaning and disinfection processes

The validation of sterilization and freeze-drying processes as well as of cleaning and disinfecting equipment including the standard-compliant verification of successful process parameters in accordance with DIN EN ISO 285, DIN EN ISO 17665, DIN EN 13060, DIN EN ISO 15883 is legally required and forms a key element of quality assurance. However, this is only possible if the data loggers are positioned correctly during validation and the reproducibility of the measurement is guaranteed.

In order to ensure that operating procedures run seamlessly, the handling of the loggers, the validation process and the documentation must all proceed as efficiently and smoothly as possible. The same applies to calculation of the lethality, the holding phase and saturated steam conditions.

The testo 190 all-in-one solution supports you with innovative data loggers, intuitive software and practical accessories to meet these challenges. So you can always rest assured that the qualification and validation of sterilization, disinfection and freeze-drying processes will be carried out in an extremely efficient manner, in compliance with the standards.
