Small, not very accurate, but tough:
This humidity gauge will require calibration straight out of the box. I used the humidity transmitter on my humidifier as a standard since it is only a month old and still accurate. An alternative method might be to use a steam bath (a boiling pot of water). Note that altitude does not matter since we're talking about "relative humidity." A steam bath will produce 100% relative humidity directly over the bath. If this review was helpful, please add your vote.
It's simple and it does the job:
It's simple. It looks nice. It will never need batteries. This is a truly lovely hygrometer. I have no complaints. You should calibrate it, either with a readymade calibration kit or a little bit of damp salt in a small container in a ziplock bag. (I read about that method on the internet, but I used a readymade kit. I have no way of knowing whether one is superior to the other. Theoretically they should give identical results.) (Calibrating it requires a screwdriver. Or possibly the edge of a dime would work.) In this era of battery operated products that go obsolete or break within six months, here's a device that has no reason to stop doing its job, ever. Kinda freaks me out a little, but in a nice way. Recommended.
does what it says and works well:
I bought three or four of these a while back not for my cigars but to simply keep an eye on humidity around my house (basement, garage, garage loft, etc.) and I'm pleased with how they work. I calibrated them all before placing them with salt and out of the box they were all within 3-4% and all are still functioning well. For the price it's hard to beat them.
cheap cheap cheap:
This is a cheaply made hygrometer. I bought a one step calibration humidipak to make sure that the two analog hygrometers were right on the money. 3 % difference between both units. The bad part is the calibration. Theres a lever in the back of the unit (under the magnet). It is way too easy to bend. That make it virtualy impossible to calibrate afterward. 1 unit down after calibration. I should have know better:"you get what you pay for". You better off buying those things locally so you can return them and not pay 7 dollars in S & H. really not worth it.
Works well enough, great for the price:
I bought a couple of these to go in my basement because I joined a winter farm share and ended up with more storage vegetables than I ever imagined. I tested it in the fridge, the freezer, on top of the humidifier, and on a rainy day, and it seemed to work well enough, giving results close to what I expected. I can't say that it was 100% accurate, because honestly I'm not that picky, but it did go way down in the fridge and freezer, and went waaaay up over the humidifier, and seems to give accurate readings in the basement compared to the other one I bought. So, good enough for me!
