Calibration Certificate:
Upon customer request, each Efento sensor can be supplied with a calibration certificate compliant with ISO/IEC 17025. The test is performed in an ILAC-certified laboratory. The calibration date is saved in the logger's memory, and the user is notified of the suggested date for the next calibration.

Data Security:
Data transmitted wirelessly between the sensor and the smartphone/Efento Gateway can be encrypted. This prevents unauthorized parties from hijacking the communication between the sensors and other devices. Efento sensor software can be updated wirelessly, allowing you to easily install any security patches that may be released.

Integration:
If you need to integrate Efento loggers with your software, cloud platform, or mobile app, we will provide the necessary documentation, libraries, and/or SDKs.
