Great Little Hygrometers

Great Little Hygrometers
I'm still setting up my terrarium and received this pair of hygrometers. They read the same straight out of the box and both indicated a temperature of 73F and a 51% humidity on one and 53% on the other. Plenty close enough for my needs. My air conditioning had just kicked on and it is set to 75F and I was standing near a ceiling vent when I opened the boxes. I see so many complaints about the placement of the 3M double-sided adhesive because they say it will block the battery cover. So I ask; what is so difficult about cutting the adhesive disks in half and placing one half on one side of the battery cover and the other half on the other side of the battery cover? You'll get the same amount of adhesion with better durability because of the wider adhesion footprint. But there's a BETTER WAY that doesn't require any use of the 3M tape at all! Please refer to the provided photo. The back of the hygrometer is exactly 1.6" in diameter and has two mounting tabs at 10 o'clock and 4 o'clock in the picture, but with reference to the front digital display, they are at 11 o'clock and 5 o'clock. I'll be covering the entire back of my terrarium with cork bark for the express purpose of mounting a large variety of Air Plants; and I'll be drilling a 1.6" diameter hole in the bark for the placement of each hygrometer (one at top of basking rock height on the hot side and one 2" above ground level centered on the cool side) and cut two tiny notches at 12 o'clock and 6 o'clock for simply placing my hygrometers in position and turning the digital display slightly to upright to "lock" them in position. To prevent wear on the cork bark backing; I'll coat the holes and notches with epoxy for a durable smooth finish. A few small holes drilled behind the air plant placements nearest the hygrometers might be necessary here to permit a slight air flow so the hygrometers can get steady samplings of the overall air within the terrarium in order to provide accurate readings. Don't know if I'll need the sampling holes yet, but only time will tell. I honestly don't know about batter life but gave that 5 Stars also in my features section of the review submission page because batteries last a very long time with monochrome LCD displays in general.

Got these to drop into my humidors. I tested them against a known, well calibrated hygrometer and they were spot on. Simple to install. Comes with a notched collar so that you can surface mount them in a hole. Comes with batteries already installed as well as a spare set of batteries. All around a great buy!

These come with double sided tape to stick them down with. It's 3M brand, but it just fell off of everything I pressed them against within 24 hours. I mounted them with copper wire and they work great. Accuracy is +-5 degrees/humidity percentage points, but that's close enough for my purposes.

I bought these to keep better track of the hot and cold zones (as well as the humidity) with my gecko's enclosure and they work like a dream! They came with spare batteries and were super easy to set up and stick in place. They have a really clear display and I've double-checked their accuracy as best I'm able to and they're near dead-on. Honestly these things are amazing and I can't believe how little they go for! Such a deal!
