Mercury Barometer - code: 2242.50

A classical instrument for air pressure mesurements. For exact measurements of air pressure and for calibrating aneroid barometers. Consists of a barometer tube mounted on wooden backboard, with one fixed scale and one sliding scale.The fixed scale indicates the height above the sea level (from 0 to 1700 m), mmHg values (from 620 to 800) and millibar (from 820 to 1070). The sliding scale, that allows the calibration of the instrument according to the height above sea level, indicates mmHg (from 700 to 790) and millibar (from 930 to 1050). A pointer sliding on the tube may be set at the pressure most recently observed. Range -10 to +60°C with 1°C divisions. Specifications
