What are the calibration requirements and frequency for each sensor?

We recommend calibration after three years in use. For efficiency reasons, combine battery replacement with calibration

Each component in the ClipR, FlexR and TMV-sensor is validated during production to confirm conformity  with its specifications. Calibration is an extra option and can be done at our factory or on-site.

Factory
➢ 10-50 finished sensors are placed on a copper pipe
➢ Temperature controlled hot water (60 °C) is circulating through the test rig
➢ A calibrated high accuracy thermometer ± 0.2 °C is used as reference measurement
➢ Sensors are activated sending their temperature to the portal
➢ Sensors outside the allowed tolerance ± 1.0 °C are discarded
➢ Calibration logs stating min and max deviation for each sensor are generated

On-site
We do not recommend on-site calibration with a clamp-on reference thermometer due to its inaccuracy. To perform a validated on-site calibration use we advise to use a Factorylab mobile testing rig. That allows for the same calibration procedure as described above.
