HX675 Hydraulic Comparator is composed of hand pump, lead screw, relieve valve, shut-off valve, booster valve, oil tank and output interface. It provides required pressure with the whole system by hand pump and uses the fine adjustment valve. It is easy to operate and labor-saving according to the hydraulic drive principle of big plunger pushing the small one. Functions HX675 can supply pressure for calibrating pressure gauges, such as pressure (different pressure) transducers, precision pressure gauges, general pressure gauges and other pressure gauges.
