Pressure Gauge Calibrator / Calibration Bench

Models: YJY-60 | YJY-600 | YJY-60A | YJY-600A

The YJY Series Pressure Gauge Calibrator is a high-precision manual pressure source designed for calibration and verification of pressure gauges, pressure transmitters, and pressure instruments. It provides stable pressure generation with fine adjustment, making it ideal for laboratories, calibration centers, and industrial maintenance applications.

Product Overview

The YJY series calibration bench uses a hand-operated screw pump mechanism to generate accurate and stable pressure. With high-quality sealing components and rigid mechanical structure, it ensures excellent pressure stability, minimal leakage, and long service life. Both standard and enhanced “A” models are available to meet different calibration requirements.
