KTJ@ Indoor Outdoor Large LCD Display Thermometer/Humidity Meter/Thermo-Hygrometer (TA318)

Did not buy from Amazon but found it for sale when searching for instructions. No instructions in the box were included, and really you do not need any but was hoping I could adjust it.My house is set to 71.5 degrees F. My indoor thermometer registers 72 degrees. This piece of junk measures over 78 degrees and 75 degrees at the same time as shown in my picture. Humidity measures 68% on my Sensi thermometer and this says 59%.I have owned a few different brands and none of them, even cheap units, were this far off. Really disappointed and I do not recommend it.

The inside and outside readings are a couple of degrees different, even though the outside sensor is right beside indoor unit. But it does what we bought it for which is help us monitor the how cold it gets in our garage.

I bought this unit to use to set-up the cooling in a vintage soda machine I had just restored; however, this unit consistently gave readings about 10-degrees colder than what reality really was.For example, at one point it said that the interior temperature was at 28.4 degrees, yet nothing was freezing inside the unit. When compared to 2 other analog gauges used in my subsequent testing, the other gauges all pegged it to be at 38 and 40 degrees, respectively, which was right where I needed it to be.Upon further research, the specs on this unit show a +-5-degree range, which is far too inaccurate, especially when compared to other units that offer a +-1-degree accuracy rating.I had to return this unit for a refund; unless accuracy is not important to you, I suggest you look elsewhere for a better-quality unit!
