PY 711 Pneumatic comparison test pump is an easy-to-carry, simple structure, operation labor-saving pressure source. It has the advantages of simple operation, smooth pressure boosting and convenient maintenance. Pneumatic pressure source is mainly used in the field or laboratory calibration of pressure instruments and meters, to provide stable pressure, while the simple structure allows you to quickly complete the calibration work. Comparison test pumps serve as pressure generators for the testing, adjustment and calibration of mechanical and electronic pressure measuring instruments through comparative measurements. These pressure tests can take place in the laboratory or workshop, or on-site at the measuring location.
Applications:
■ Gauge calibration
■ Precision pressure measurement
■ Pressure transmitters calibration
■ Pressure switch and Safety relief valve test
■ Pressure regulator test
