Conex JDB-1 Digital Barometer
LARGE Display - Easy To Read From Across A Room!
The JDB-1 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 Millibars (mB). The JDB-1 also indicates the pressure trend (see page 2), 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 may be wall-mounted or set on a shelf, and uses a standard 9-Volt alkaline battery which lasts about a year.
