Sino HS728 Hydraulic Comparator

To calibrate high pressure instruments against a standard gauge, the HS728 Hydraulic High Pressure Comparison Pump generates pressures of up to 1000bar, 1200bar, or 1400bar. It is equipped with a hand pump that can quickly pressurise the entire system; the perfectly integrated operation of the hand pump and booster assists the user in achieving high pressure point calibration, closing Shut off valve during pre-pressurizing 250bar in order to obtain high pressure ranges. In the process, the lead screw adjusts the exact pressure values. The working medium’s balance is indicated by a specially designed transparent oil cup. It is widely used in the laboratory to calibrate pressure gauges.
