I have a ACU-RITE unit and I want to calibrate this, so I can be as accurate with my humidity as possible. Does any body know how to do this???. I have heard that you put it in a solution of highly concentrated salt water, insert probe and wait. OK so what concentration of salt water??, how long do you wait for the reading to calibrate???, and what should it finally read before being considered calibrated ??.
