GDP-compliant data logging powered by digital temperature sensors

Sensirion is offering the new STS32 temperature sensor which will be available from October 2020 onward. This digital sensor is supplied with an ISO 17025-accredited, three-point calibration certificate. The calibration data and the sensor specs are compliant with GDPs for pharmaceutical and medical logistics. Data logger manufacturers can remove costly and technically challenging calibration operations by combining the STS32 into their loggers.

Based on the STS3x platform, the new device is a digital, I2C-based temperature sensor. It offers a GDP-adapted accuracy specification and incorporates a three-point calibration certificate provided by the company's new ISO/IEC 17025:2017 accredited calibration laboratory. The calibration setpoints are T = -30C, 5C, and 70C. All the values are offered in a machine-readable CSV file format and can be associated with the relevant sensor by using its unique, unalterable serial number. The metrological traceability of the calibration conforms to Chapter 6.5 of ISO/IEC 17025:2017, commonly referred to in relation to NIST traceability or traceability to other national metrology institutes, in accordance with the CIPM MRA.

Calibration certificates and data for each sensor can be downloaded from a server address provided in the shipment documents, allowing efficient processing by automated systems. The device users can merge the calibration data delivered by the sensor with the calibration information required for their loggers. The calibration process can, therefore, be entirely covered by employing a digital, precalibrated temperature sensor, all while satisfying the pharmaceutical and medical industries’ stringent quality demands.
