HS728 Hydraulic Comparator

◆ Generated pressure range:(0~1000)bar, (0~1200)bar;(0~1400)bar
◆ Working media:25#Transformer oil
◆ Adjust resolution: 10mbar

Product Description

HS728 Hydraulic High Pressure Comparison Pump is generated pressure up to 1000bar or 1200bar or 1400bar to calibrate high pressure instruments against a standard gauge. It is fitted with hand pump which could quickly pressurize to the whole system; perfectly integrated operation of hand pump& Booster helps user to accomplish high pressure points calibration, closing Shut off valve during pre- pressurizing 250bar in order to get high pressure ranges. The lead screw adjusts the exact pressure values in the process. A specially designed transparent oil cup marks the balance of working medium. It widely calibrates pressure gauges in the laboratory.
