THIS PRETTY RARE ANTIQUE MICRO-MANOMETER (MICROMANOMETER) WAS MADE BY AIRFLOW DEVELOPMENT LIMITED IN THE UK. THE COMPANY WAS STARTED IN 1955 AND HAS BRANCHES IN GERMANY, CANADA, NEW ZEALAND CZECH REPUBLIC AND NORWAY. THE MICRO-MANOMETER WAS DISTRIBUTED BY D. GILES (SCIENTIFIC) HERE IN JOHANNESBURG, SOUTH AFRICA. THE NEWER METERS ARE NOW ALL ELECTRONIC, MAKING THIS A VERY COLLECTIBLE ITEM.
MANY TECHNIQUES HAVE BEEN DEVELOPED FOR THE MEASUREMENT OF PRESSURE AND VACUUM. INSTRUMENTS USED TO MEASURE PRESSURE ARE CALLED PRESSURE GAUGES OR VACUUM GAUGES. A MANOMETER COULD ALSO REFER TO A PRESSURE MEASURING INSTRUMENT, USUALLY LIMITED TO MEASURING PRESSURES NEAR TO ATMOSPHERIC. THE TERM MANOMETER IS OFTEN USED TO REFER SPECIFICALLY TO LIQUID COLUMN HYDROSTATIC INSTRUMENTS. A VACUUM GAUGE IS USED TO MEASURE THE PRESSURE IN A VACUUM -WHICH IS FURTHER DIVIDED INTO TWO SUBCATEGORIES, HIGH AND LOW VACUUM (AND SOMETIMES ULTRA HIGH). THE APPLICABLE PRESSURE RANGE OF MANY OF THE TECHNIQUES USED TO MEASURE VACUUMS HAVE AN OVERLAP. HENCE, BY COMBINING SEVERAL DIFFERENT TYPES OF GAUGE, IT IS POSSIBLE TO MEASURE SYSTEM PRESSURE CONTINUOUSLY FROM 10 MBAR DOWN TO 10−11 MBAR.
