The SK-2200-DPG Hand Pump Pressure & Vacuum Calibrator is a precision calibration instrument engineered for professionals in calibration labs, industrial maintenance, and field instrumentation. Designed to generate both pressure and vacuum from ambient to -1 Bar and up to 25 Bar, this portable calibrator allows accurate testing and calibration of pressure gauges, transmitters, sensors, and control instruments. Equipped with a high-accuracy digital master gauge (±0.5%), stainless steel welded piezo sensor, and leak-proof fittings, it ensures stable, contamination-free performance even in demanding industrial environments. The rugged aluminium construction and ergonomic hand pump deliver smooth pressure generation with long operational life exceeding 1 million cycles. Its multi-unit display (bar, psi, kg/cm², MPa), auto shut-off battery system, and compact design make it ideal for both laboratory and onsite calibration tasks. Whether you're calibrating pressure instruments in manufacturing plants, power stations, HVAC systems, or test laboratories — SK-2200-DPG delivers accuracy, reliability, and professional-grade performance.
