JY25 Piston Gauge: High-Accuracy Pressure Calibration with a Tungsten Carbide Core
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.

| JY-6 | 0.1 ~ 6 | ±0.05% |
| JY-25 | 0.5 ~ 25 | ±0.05% |
| JY-6 | 1 ~ 60 | ±0.05% |
| JY-100 | 1 ~ 100 | ±0.05% |
| JY-160 | 2 ~ 160 | ±0.05% |
| JY-250 | 5 ~ 250 | ±0.05% |
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.
