Utilizing a high-resolution screw-press mechanism, the comparator enables smooth, effortless pressure generation with extremely fine incremental adjustment, allowing technicians to achieve exact pressure set-points without the overshoot and instability commonly associated with conventional hand pumps. This ensures a reliable and repeatable pressure source that is ideal for accurate calibration and verification of sensitive pressure instruments.
The pneumatic comparators are available in multiple pressure ranges, covering vacuum from –0.95 bar up to positive pressure ranges of 2 bar, 10 bar, and 35 bar, providing flexibility to support a wide spectrum of calibration requirements. These units are particularly well suited for applications involving pressure transmitters, differential pressure sensors, gauges, and switches operating in low-pressure or clean-media environments such as laboratories, HVAC systems, pharmaceutical processes, and industrial instrumentation workshops. With their robust construction, precise control capability, and stable pressure output, the Pneumatic Pressure Comparator Series delivers the accuracy, consistency, and operational confidence required for professional calibration and testing environments.
