Text in the certificate
This document applies to Logmore Model 2 data logger with serial number #224215. Logger #224215 was assembled and tested at: 2021-08-02 09:30:18 UTC
Accuracy of the Si7055 temperature sensor used in Logmore Model 2 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.
