FAQ - Frequently Asked Questions

Microsensors

How often do the sensors need to be calibrated?

Depends on the operating conditions. In the museum climate with values ​​around 50%rH and temperatures around 20°C, an annual check is sufficient. If used outdoors or in high humidity areas, a six-monthly inspection may be necessary. This depends on the requirements for the precision of the measurement.

Can the sensors be calibrated?

The sensors are checked in our calibration chamber and if there are deviations > Specification replaced by new sensor elements. Another option is to measure using the CanMeleon 2.0 or CanMeleon Compact. Here it is possible to compensate for smaller deviations.

Are the sensors interchangeable?

Yes, the sensors are interchangeable.

How long can the sensors be used?

Depending on the location and environmental conditions from 10 years to approx. 25 years

Are the sensors available in different designs or colors?

Yes, the sensors are available in a wide variety of designs. Depending on the needs of the area of use, the sensors can be made of different colors and materials.
