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.

IÂ’d be lost without this piece of small tech. Buy a humidor, upgrade and get it half price is a bargain! Or if youÂ’re upgrading a less reliable hygrometer, then look no further. The readings are accurate for me, double tested and itÂ’s plain sailing from here. ItÂ’s not as stylish as the Adorini time dial pieces that are built in some of their humidors, but I want accuracy over style. For the price, you cannot go wrong here.

First let me thank Caliber so much for this smart IV - Digital Hygrometer Thermometer. High quality, compact and practical, accurate readings, and ability to adjust calibration, it is the best Hygrometer ever. Thank you so much C.GARS , Michelle Adler for all excellent choices and services. ✨

Not a review as such, more a question Ive noticed just now, as ive just received some cigars from c.gars and just put them in my Boveda Acrylic Humidor, that the temperature reading on my caliber IV Hygrometer seems to be jumping between 69 degrees F and 72 degrees F every now and then (although as i type it seems to have settled on 72 degrees F, As a new cigar smoker i'm a bit panicky about getting things right lol so wondered if this is normal or should i calibrate the hygrometer again? Also, is 72 a bit high temperature wise? Anyway, other than being unsure about that ive always been happy with the hygrometer.

Reliable, accurate and very easy to set up. I feel a lot more confident having it in the humidor.

The Caliber IV is absolutely fantastic, what I like most about this hygrometer is the precision/accuracy, the digital display and it's slim but sleek profile design. Suitable to fit inside any travel/small desktop humidor. If you want an efficient and reliable digital hygrometer, pickup the Caliber IV (It's even supplied with the batteries!)
