Micro-pressure air pressure calibrator is used for calibrate micro (differential) pressure transmitter,
micro-pressure sensors, micro-film and micro-pressure gauges and other instruments. In the digitalpressure calibration system, which can provide a stable and pressure changes can be controlledsufficiently small micro-pressure source. Simple operation, easy maintenance buck stable by theexternal temperature is small, the minimum controllable adjustment fineness, excellent sealingperformance, near zero leakage.
