The 00972 Acu-Rite Wireless Indoor/Outdoor Thermo-Hygrometer & Moon Phase Atomic Clock has an unusual horizontal format. The Acu-Rite 00972 would look sharp on an executive desk, the mantel, even on the nightstand. The normal display includes indoor and outdoor temperature and humidity, date, calendar display, moon phase display, and in larger numbers, the time.  The time and calendar functions are all atomic, that is, they receive radio broadcasts carrying highly accurate timing information, and set themselves.

Pressing the Min/Max button displays the minimum and maximum indoor and outdoor temperature and humidity readings experienced.  Minimum and maximum values are reset automatically every 24 hours.

The Acu-Rite has alarm clock functionality with a 5 minute snooze alarm.  The alarm is an electronic crescendo alarm.  It is not extra loud however, a word of caution for those heavy sleepers or those whose hearing isn't what it used to be. 

The Acu-Rite 00972 can receive and display temperature from up to three remote sensors (selectable by the "channel" button).  One remote sensor is included, additional sensors are available separately. The remote sensor has a 10 foot long detachable wire probe that may be used to run out a window for extreme climates, monitor refrigerator, freezer or hot tub temperature, anyplace you can't put a remote. The remote temperature sensor is white in color and about 4 inches tall by 2-1/2 inches wide by 1-1/8 inch deep in size. The sensor has a small temperature display of it's own.  The sensor can be used with or without the removable wired probe. 

Temperatures may be displayed in °F or °C. Indoor and outdoor temperature and humidity digits are just under 1/2 inch tall, with tenths of a degree about half that size.  Date digits are about 3/8 inch, while the hour and minute digits are about an inch, with seconds being about 1/2 inch. Low battery indicators are included on the display to indicate a low battery condition at either the main unit or the remote.

Operating (indoor) temperature range of the main unit is 32°F to 122°F (0°C to 50°C). Operating temperature range of the included remote sensor is -4°F to +158 °F (-20°C to 70°C) without the wireless probe, or -22°F to +158 °F (-30°C to 70°C) using the probe. Indoor and outdoor humidity range is 20%-99% RH. Maximum transmission range of the remote sensor is 100 feet. 

This product comes with a 1-year factory warranty.
