- Not recommended, due to temperature inaccuracies, and a complete failure of the relative humitity readout.
- 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. - 2008-11-25, 0 of 0 people found this review helpful, Rated:
- Good but the remote temp sensor is nearly useless
- The basic thermometer/hygrometer part is very good. However, the remote sensor is nearly useless as it is connected by a cable to the display. They tell you to bore a hole in the wall to take the sensor outside but the cable cannot be detached which means the hole would have to big enough to fit the whole sensor through. Anyways, who wants to make a hole in the wall to the outside .. hot/cold air would be rushing in through it.
