JY25 Piston Gauge: High-Accuracy Pressure Calibration with a Tungsten Carbide Core
Company Profile
Xi’an Yunyi Instrument Co., Ltd. is a national high-tech enterprise, specializing in the R&D, production and sales of pressure meter,level meter, flow , temperature instrument and automatic control equipment.The 2638-square-meter workshop has its own machining department and production line, focusing on R&D and production of customized and industrialized automatic instruments, providing complete set of customized solutions to create high-quality instruments.
Engineered for metrology labs that cannot compromise on accuracy, the JY25 Piston Dead Weight Tester sets a new standard for pressure calibration. It features a tungsten carbide core for unmatched stability and minimal deformation. Paired with an isooctyl sebacate working fluid, it delivers exceptional sensitivity to reliably calibrate even the most precise pressure instruments.

Key Features & Advantages
Robust Core: Tungsten carbide piston and cylinder for high wear resistance and stable performance across a wide ambient temperature range (20±5°C).
Precision Engineering: Low-center-of-gravity weights and direct loading ensure smooth piston rotation, minimal pressure fluctuation, and accurate readings.
High Sensitivity: Use of low-viscosity isooctyl sebacate medium guarantees high sensitivity, especially above 25 MPa.
Advanced Design: Non-magnetic stainless steel weights; integrated piston displacement sensor for clear, intelligent position monitoring.
Easy Operation: Features a wide range and a user-friendly pressure regulator for smooth operation even at high pressures up to 250 MPa.
Typical Applications
This tester is widely used for the calibration and testing of:
Digital Pressure Gauges
Precision Pressure Gauges
Pressure Transmitters
And other pressure instruments.
