Review on 12-Pack Small Digital Temperature Humidity Meters Gauge Indoor Thermometer Hygrometer LCD Display Fahrenheit (℉) for Humidors, Greenhouse, Garden, Cellar by Blake Pudic

I ordered another set of hygrometers and had to return them as I couldn't change the temperature from C to F there was no switch where they said he was. This set only reads degrees Fahrenheit so it was perfect for me and the temperature was accurate to +/- 0.5 degrees with a calibrated thermometer. I bought them mainly because of the hygrometer function. I tested them with Boveda calibration kits and four of them were correct and the other two were accurate to +/- 1% RH. Since they're reported with an accuracy of +/- 5%, that's pretty damn good. I will be using these in my musical instrument cases to test RH. The rest will be checked later 2/2619 Tested the rest and only one was around +2% RH, all others were +/- 1% RH and +/- 1 degree F in temperature. These items are good for reference, if you have exotic plants or animals or a really expensive stringed instrument, you want to have a premium instrument to protect your investment.
