Conex JDB-2 Digital Barometer

LARGE Display - Easy To Read From Across A Room!

The JDB-2 incorporates large easy-to-read digits (you can read it from across the room), a trend indicator, and battery operation to make weather watching easier than ever.

The JDB measures the barometric pressure every 15 minutes and displays in inches of mercury (In-Hg), or in Millimeters (mmHg). The JDB-2 also indicates the pressure trend, the best predictor of weather changes.  A rising trend generally indicates improving weather, while a drop often means deteriorating weather.   A sharp drop in pressure is indicated by a series of beeps.

The JDB-2 may be wall-mounted or set on a shelf, and uses a standard 9-Volt alkaline battery which lasts about a year.
