Customer Reviews:

  • EXTREMELY ACCURATE! Buying A Second Unit
    I tested this hygrometer in a Humidipak Calibration Kit that is exactly 75.5% Relative Humidity. This unit displayed between 75 & 76% which is pretty much dead-on accurate! It only shows in 1 point increments not tenths which is just fine. I was surpised since it only costs $20 and its as accurate as the professional testing equipment. I am currently using this inside my cigar humidor but will purchase a second one for our bedroom....more info
  • Great Wine Cellar accessory
    Great for the wine cellar and cigar humidor. Even better was the size - very small and so is not noticeable. ...more info
  • Good hygrometer
    Sometimes it reads a little different than it's twin sister hygrometer (when they are right next to each other). Can't say it's the greatest ever but fantastic for the price....more info
    After reading many, many reviews for humidistat's on the web I was beginning to think that a accurate one did not exist for less than $500. This one seems to be very accurate and the price is very nice. It doesn't need calibrating. It will track a high and low temperature and humidity. It is small enough to fit almost anywhere. The variance is said to be = or - 1%, that is good enough for me. If you want something more accurate your going to pay for it. Good Luck!...more info
  • Best Hygrometer For The Price!
    This is the best Digital Hygrometer you can get for the price. It is very accurate and fits securely and easily in my 50 cigar humidor. Not much else to say....more info
  • Caliber III Thermometer Hygrometer
    I bought three Caliber III Thermometer Hygrometers for my cigar humidors. It is the most accurate thermometer/hygrometer I have ever used. All three vary only +/- 1 degree. I highly recommend these units. has the best price and quick delivery. Caliber III Thermometer Hygrometer ...more info
  • It works
    It works. Can't verify the calibration but it seems fine.
    Good enough for what I want it....more info
  • I give this a thumbs up.
    I read several reviews on Amazon and elsewhere and for the price ($16.99 from CigarsExtra)bought two.

    They track very closely,1-2 % of each other.

    Example: T = 75.0F 76.5F
    RH = 44% 43%

    The display is easily to read,and there is a small switch conveniently located on top that allows temperature to be displayed in C or F.

    The instructions caution against using the salt test or a wet towel to test the accuracy of the Caliber III. Same goes for placing it in water or an oven. There is no way to adjust the unit.

    That said,very precise for a hygrometer in the $20 price range.

  • Ideal
    I bought this to monitor the humidiy in my guitar humidor. Simple to use and compact. Helped me make changes to increase the humidity and temperature to acceptable levels. This was a good buy for my purposes and I reccomend it....more info
  • Good product
    This product seems to work good. My cigars are in good shape. Price was good also. ...more info
  • Does what it is supposed to do...well.
    Nice. Small. Accurate. Good value. There isn't much more to say. The only negative is that it is a little difficult to read in very low light conditions, but that is fine for me....more info
  • Works great, great price.
    Seems to track humidity in my Chicago condo well, and helped confirm that my humidifier was reading correctly. The min/max feature is nice too, but I'm dubious about its readings sometimes - I pretty sure my place doesn't drop to 7% during the day, but who knows?...more info
