Comparator (Hydraulic)

Overview:

The Hydraulic Pressure Comparator is engineered to deliver precise, stable, and controlled pressure generation for high-pressure calibration applications, with multiple range options available from 0 to 200 bar, 0 to 400 bar, 0 to 700 bar, and up to 0 to 1000 bar. Designed as a professional benchtop calibration solution, it incorporates a heavy-duty screw-press mechanism that enables technicians to generate and fine-tune pressure smoothly with minimal effort. This advanced mechanism eliminates pressure fluctuations and overshoot commonly associated with conventional hand pumps, ensuring rock-solid stability during critical calibration procedures and allowing users to achieve exact pressure set-points with confidence.

The comparator provides direct, leak-free comparison between a reference pressure instrument and the device under test, making it ideal for accurate verification of high-pressure gauges, transmitters, transducers, and safety relief valves requiring traceable results. Built for demanding industrial and laboratory environments, the system offers the mechanical strength and durability necessary to handle extreme pressure conditions while maintaining precise incremental control. Its stable pressure platform is particularly valuable for testing hydraulic components, wellhead instrumentation, and safety-critical devices across industries such as oil & gas, power generation, heavy manufacturing, and process automation. By delivering reliable and accurate set-point control across the full range spectrum up to 1000 bar, the Hydraulic Pressure Comparator ensures measurement confidence, operational safety, and compliance with stringent quality and regulatory standards.
