I always get a giggle (simple mind, simple pleasures) when I see a display  
rack of thermometers in one of the Big Box stores. One can almost be  
assured that every one of the different brands (and sometimes even the  
same model within the same brand) will have a different reading.

How to determine which of Ben's electronic hygrometers is most accurate ?

I'd say buy one of the $7 analogue hygrometers and calibrate it as per the  
instructions in the CMHC blurb that I mentioned to Sacie.

And then compare its readings to that of the digital ones .

And then keep the analog unit and get rid of the electronic ones on Kijiji.
