Relative humidity calibration

If your company depends on accurate and traceable relative humidity calibration of the measuring equipment, you’ll be pleased to know that specialist help is at hand. At Minerva Metrology & Calibration, we’ve been helping calibration laboratories and departments with service/maintenance and recalibration of their primary and secondary standards for more than 30 years.


You can be assured that your most accurate relative humidity calibration and measuring instruments are in good hands with us.

Our team works quickly, reliably and transparently to provide you with a carefree traceability.

What is relative humidity calibration?

In many machines, devices and rooms, relative humidity and/or dew point is measured. This is essential for optimal performance of the device, process or room in question: think of a sauna, the indoor climate in fruit and vegetable greenhouses, and during the transport of vegetables, fruits and medicines.

Other examples of where humidity calibration is required are manufacturing processes in the refining industry, the food industry, the chemical industry and in pharmaceutical production. In those industries, relative humidity sensors transmit the measured value to a central control computer.

Humidity calibration is comparing a relative humidity measuring instrument (machine) or device with a calibration standard. This is how we determine the measurement deviation (bias), by comparing with a calibration reference or calibration standard.

We compare a number of measured values of  your instrument with a calibration standard that can be traced back to (inter)national standards. We calculate the relative humidity (RV)  from the vapor pressure (e) and the saturation vapor voltage (eS) at the prevailing temperature (T).
