The range of compressors is designed to test, adjust and calibrate measuring instruments mechanical or electronic pressure by comparison (pressure gauges, pressure transmitters or sensors or switches). These generators are equipped with a pressure tank visible level, two valves connected by a set of two-stage variable volumes. The capstan can generate the pressure pushing the fluid through the variable volumes to fittings provided for receiving the pressure instruments comparing. These compressors are designed for calibration comparison. They are sturdy and easy to use and have a very high long-term stability. They have the opportunity to grow in dead weight tester by simply adding a kit with : a piezometric and a set of weights.
