Manual pressure calibration pump DY-WYL

low-pressurefor pressure generation

DY-WYL portable micro-pressure pump (-50-60KPa) is characterized by simple operation, easy maintenance, stable pressure rise and fall, large range fine-tuning, push-pull pressure, can be far transmission verification instrument, small can be controlled to adjust the fineness of high. Integrating positive and negative pressure, convenient switching between positive and negative pressure, no leakage and other characteristics, it is a stable pressure source for checking pressure (differential pressure) transmitter, pressure sensor, pressure gauge and other pressure instruments and meters.
