Recalibrate loggers

Technically the sensors do not need to be recalibrated every year since drift is minimal. However, due to industry guidelines and our customers' own quality systems, a yearly re-calibration of each sensor are required.

Many industries have strict regulations demanding temperature sensor recalibrations in 12 or 24 month cycles. The regulations stand to ensure measurement accuracy.

The industry standard is to recalibrate old devices one by one. In the Logmore service the cumbersome recalibration is replaced by annual replacement loggers where needed. The service always includes a freshly calibrated data logger tag, along with a calibration certificate.

The replacement method allows companies to seamlessly monitor circumstances with calibrated loggers.

Logmore calibrates Logmore QR data loggers according to the NIST and ISO17025 standards. The calibration guarantees a maximum of 0.5°C inaccuracy in measurements.

An example of a calibration certificate:

This document applies to Logmore Model 3 data logger with serial number #0000440. Logger #0000440 was assembled and tested at: 2020-02-13 09:23:10 UTC Accuracy of the Si7055 temperature sensor used in Logmore Model 3 data logger: Typical ±0.4°C, absolute maximum ±0.5°C This accuracy applies to full measurement range of the sensor: –40.0 °C to +125.0 °C To ensure these verifications are met, every individual sensor has been factory calibrated to these standards as stated on page two. Each data logger unit has been tested to correctly communicate with the temperature sensor as well as the cloud system. All data moved to the cloud service is encrypted with highly secure encryption algorithms. By all these means, and other additional security measures, we can ensure the validity and accuracy of the data system wide.
