Caliber IV - Digital Hygrometer Thermometer

Date Added: Monday 01 September, 2025 by Paul

I bought this Caliber IV digital hygrometer to replace the old round 'analogue' one in one of my humidors which never seemed to vary much in its readings. This is so much better and I think good value for money.
Have compared it with my other digital hygrometer and believe it's pretty accurate. Very pleased and would recommend.
