Crazyview 2 Pack Mini Digital Hygrometer Indoor Outdoor Thermometer Hygrometer LCD Temperature Humidity Meter Gauge for Cigar Humidor, Guitar, Garden

This set reads degrees F, it is perfect for me and the temperature was accurate /- 0.5 Degrees with a calibrated thermometer. I bought them mainly for the Hygrometer feature. I tested them with Boveda calibration kits and four were right on and the other two were accurate to /-1% RH. Since they are listed at /-5% accuracy that is pretty darn good. I will use these in my musical instrument cases to check the RH. There is only one was off by 2% RH, all the rest were /- 1% RH and /- 1 Degree F on temperature. These items are good for a reference, if you have exotic plants or animals or a really expensive stringed instrument you would want to get a top of the line instrument to protect your investment.

After a week they do work.

I got these for my cigar humidors and they are within one to two percent of my more expensive hydrometers. It's all relative anyway so they work good for this purpose. Great value.

They're cute little units for thru panel snap in mounting. They come with two LR44 batteries pre-installed and running. Cupping it in my hand and breathing on it made an immediate change. The LCD is clear and easy to read. The humidity is about 1/2 tall on the left half of the display. On the right the Celsius temp is displayed on top with a percentage sign below. There are no switches or buttons. The display temp appears to be fixed as Celsius with no option for Fahrenheit. The rectangular module clips in place and does not have to be dismounted to change the two batteries. There are no instructions or dimensions for mounting. The module mounting dimension appears to be 1-3/4" by 1". The mounting tabs seem to imply a max panel thickness of 3/16" or at most 7/32" Retention in thicker wood panels should be ok. The air intake port is on the rear and should be open to the air for proper operation. These were purchased specifically for a humidor project but look so nice I'm thinking of using one in a desktop weather station. I would have rated these 5 stars if there were a single WORD of instruction.

The Temperature/ Hydrometers arrived very quickly. I bought them to place in my new egg incubator to have a piece of equipment reading the heat and moisture to validate the incubator's monitors. These little monitors are small enough to fit within the egg slots. This is my first time so I am on a learning curve. I am fighting to keep the moisture levels within the approved boundaries. These little monitors are a real help.

These meters are a snap in mount instead of fully encased.

i steel have no got this item

to big to fit in my humidor.
