Caliber IV - Digital Hygrometer Thermometer

Date Added: Thursday 25 September, 2014 by Ross

My first two purchases were the Xikar Hygrometer Rectangular version. On both of these Xikar hygrometers the tolerance is 2% either way whereas the Caliber IV is 1%. Both Xikars were not within specification using the Boveda Hygrometer Test kit. Bought a Caliber and popped it into the bag and within 24 hours it is reading bang on 75%, as it should. Both Xikars are being returned for the Caliber IV. Fantastic hygrometer with easy to read Relative Humidity (RH) and Temperature and on top of that you can alter the device if it does start to drift. Please don't make the same mistake I did. Go for one of these. You won't be disappointed!
