An integral transducer and digital display allow easy and accurate pressure readings. Two separate versions measure pressures in the range of ±15 psi or ±100 psi. A range switch allows measurement in units of psi or kPa for the 100 psi version, and psi or mm Hg for the 15 psi version. Pressure can be read on the built-in LCD display or relayed to a chart recorder, oscilloscope, or computer.

PM Series pressure manometers come with 4 feet of 1/8-inch ID soft vinyl tubing. A mini-phone-to-BNC cable for the recorder output is also available (Part #CBL102). Standard versions are equipped with a nine-volt alkaline battery. Rechargeable versions come with nickel/cadmium battery and charger.
