Kitchen and Housewares Reviews of Holmes Digital Thermometer and Hygrometer
Customer Review: Not recommended, due to temperature inaccuracies, and a complete failure of the relative humitity readout.
Summary: 3 Stars
This unit provides both temperature and relative humidity readouts. You can check both inside and outside temperatures in either Fahrenheit of Celsius. The outside temperature is provided to the display through a wire attached sensor. I located the display near a window and ran the wire under the lower sash and over the exterior sill, so that it was not necessary to drill any holes.
The two temperature sensors are accurate (relative to each other) within an error of about 2 degrees Fahrenheit. This was determined by initially leaving a unit inside for a day, and noting both indoor and outdoor sensor readings. Although both sensors were indoors, and measuring the same ambient temperature, the difference between them was about two degrees. The relative humidity readout of this unit has stayed permanently stuck at 20% and is, thus, of no value.
I initially bought two of these units on sale. I use the one with the most accurate temperature readouts for indoor and outdoor temperature readings, which are usually within two degrees of other thermometers around the house. The second unit's hygrometer, although not frozen, is inaccurate.
The main goal motivating this purchase was to get reasonably accurate relative humidity readings. Owing to their failure to provide adequate relative humidity readings, and their temperature inaccuracies, the Holmes Digital Thermometer and Hygrometer is not recommended.
