The La Crosse Technology WS1025 Window Thermometer is a really cool new digital outdoor thermometer. It mounts on the outer surface of a window. Through the window from indoors, you can view the current outdoor temperature in big, bold digits, and you can simultaneously view minimum and maximum outdoor temperatures recorded in memory. The digits seem to float in the WS1025's gray-green tinted plastic LCD panel. On this particular thermometer, temperatures are displayed in °F only. You'll appreciate how easy the WS1025 is to set up and use.

Here are some things you'll want to know about the WS1025: First of all, you need to select a location for mounting in an area that's both easy to view and out of direct sunlight. Mounting the WS1025 in direct sunlight causes artificially high temperature readings. The main body of the WS1025 (the portion containing the circuitry and display) snaps onto a bracket, or holder, that adheres to window glass by means of two adhesive patches. Thus, the window area on which you mount the WS1025 must be absolutely clean and dry when you install it. Also, before you use the WS1025, you need to remove the protective film from both sides of the transparent display area. You'll appreciate the fact that the thermometer main body with display can be easily pulled off of its mounting bracket for window cleaning. 

As mentioned above, setting up the WS1025 is a breeze. You first open the battery compartment with a Phillips screwdriver and remove the plastic insulating tab from between the AAA alkaline battery (which is included with the WS1025) and the positive terminal. This activates the temperature display. Then close the battery compartment.

Because the min/max temperature memory of the WS1025 automatically resets each day, this thermometer has an integral quartz clock that must be set so that memory resets occur at the proper times. This is easy to do. You press the MODE button to enter the setting mode and use the + button to advance the flashing hour digits to the correct local time. You press MODE again and use the + button to advance the minutes digits to the correct local time. (By the way, AM or PM is conveniently displayed to the left of the time.) You then press the MODE button again to exit the setting mode. (The WS1025 does not have an timeout feature and  will not exit the setting mode automatically.) The maximum temperature now automatically resets at 8:00 A.M., and the minimum temperature now automatically resets at 8:00 P.M.

The WS1025 is cleanly and simply styled. As stated above, the display area of the main body of the thermometer is transparent plastic with a gray-green tint. It extends down from a silver-colored compartment that contains the WS1025's circuitry and battery.  The bracket that holds the main body is also silver in color. With its small size (just over 4 inches tall), handsome styling, min/max memory, and big display, the WS1025 is a cool-looking and reasonably priced alternative to the more common analog thermometers that mount outside of a window.
