Calibration certificate of Humidity Analog Sensors in PSoC1 kit.

I'll stick my neck out here (I don't have a kit) and say that if you want a fully traceable calibration (by NAMAS certified test house in the UK) of a humidity sensor expect to pay at least £100 for a single temperature three point cal and much more if you need a range of temperatures.

Calibration of humidity sensors is difficult and slow.

These people can do it:

there are lots of others.
