1. INTRODUCTION
The measurement of pressure and the rate of
change of pressure are important meteoro-
logical observations with regard to forecasting
weather conditions.
The recording of atmospheric pressure
changes enables meteorologists to make short
term local forecasts. The most convenient
method of studying the rate of change in
pressure is with the aid of a Barograph, which
records the pressure variations graphically
onto a revolving chart drum.
Two versions of the barograph are available:
the Small pattern and the Display pattern. Both
versions can be supplied complete with a
UKAS (formerly NAMAS) calibration certificate.
