Are you a stickler for accuracy? Then you'll love this affordably-priced digital hygrometer-thermometer with its own calibration knob feature. When used with a Humidipak 'One-Step Calibration Kit,' you can turn the knob to fine-tune the hygrometer, ensuring your cigars are kept at the right RH.
I ve had this hygrometer for almost a year and it has been extremely reliable. Just be sure that if you have to calibrate it, adjust the knob while it is still in the ziploc bag. The process is very easy and I d recommend it to anyone
I orderd 2 of these upon delivery i activated 1 it was about 3 percent high with salt test easy to adjust and works well. A few weeks later actavated 2nd upon calabration test had to fully adjust to the negative limit called costumer serv. Christina was very helpful and shiped me a new one no prob.Sent in the defective one the new one spot on rite out of the box. Alls good return service was exelent.
It was good for the first year until I changed the battery. Then despite attempts to adjust it, it no longer gave anywere near an accurate reading.
Perfectly set out of the box I done the salt test and past. But the set up kit recommend for setting up hydrometers and passed as well . Trust me you can't go wrong with this one plus its pretty much the same price on amazon and as other cigar outlet stores I'm cheap and don't like to spend more when I can help it this is perfectly priced and will last a long time. Period!!!
