When I was fighting a humidity issue in my workshop, I realized I couldn't solve it without monitoring results - and picked up a SensorPush Wireless Hygrometer with Alerts for that purpose. It quickly became apparent that, although the SensorPush is awesome, I wanted to be able to see the humidity at a glance when I'm out there - so I also picked up a ThermoPro TP55 Digital Hygrometer that I could just stick to my gun safe using magnets. If I hadn't been using the SensorPush, I probably would have been happy with the ThermoPro - but I did have a couple of issues with it: 1) The humidity level didn't match the levels from the SensorPush - which was driving me nuts. 2) Even when the SensorPush reported wide swings in relative humidity, the ThermoPro seemed to stay stuck. It was always reporting 48-52%, even though the SensorPush reported a far larger range. After a couple of weeks, I came back to Amazon and picked up the AcuRite 01080 Hygrometer - which turned out to be an excellent decision. 1) The readings on the AcuRite are FAR faster, so it reports the same swings as the SensorPush. 2) The AcuRite supports calibration (which I did using a Boveda One-Step Calibration Kit ). It's a little hard to calibrate the Acurite inside the Boveda bag; but, only took a few minutes using the button map from the instruction pages. (The problem is you can't see the buttons - you have to feel for them.) It's interesting that the AcuRite was off by almost 5% out of the box - but now it matches the SensorPush (which is also calibrated) perfectly. After reading reviews, I almost didn't buy the AcuRite because of complaints about the display contrast and size. Personally, I don't see the issues at all - it seems plenty big for my purposes; and, although the contrast definitely isn't as good as the sticker that comes on it - it isn't bad either. The contrast is pretty much comparable to any other digital display. If you're comparing the AcuRite vs the ThermoPro, the ThermoPro has an easy-to use touchscreen and backlighting, while the AcuRite seems to focus more on being a good hygrometer. If you're going to be constantly switching back and forth between Celsius and Fahrenheit, or want a backlight, then consider the ThermoPro - otherwise just grab the AcuRite, it really is an excellent unit. [*** Update 12/12/2017 ***] This has worked so well that I ended up getting another one to track the humidity by my main gun safe. After letting it settle for about 8 hours and calibrating it - it works just as well as the first and tracks the other sensors perfectly.
