Product Advantages
The core value of liquid piston pressure gauges lies in their unparalleled precision, stability, and authority.
1. Reference-grade accuracy: Achieving ±0.005% of reading (national reference standard), it serves as the benchmark for providing the most reliable and precise pressure source, ensuring error-free measurement traceability.
2. Exceptional long-term stability: Core components (cylinder-piston assembly) utilize high-strength, low-deformation, wear-resistant materials like tungsten carbide, delivering stable performance and extended calibration intervals to effectively reduce long-term operational costs.
3. Exceptional Reliability: Based on classical physics principles, the stable structure exhibits strong interference resistance, minimally affected by ambient temperature, humidity, or electronic disturbances, ensuring high data reproducibility.
4. Extensive Range Coverage: By configuring different piston systems, the range spans from micro-pressures of several kPa to high pressures exceeding 500 MPa, offering broad applicability.
5. Global Standard Compliance: Design, manufacturing, and certification strictly adhere to national and international standards such as JJG 59-2022 and ISO 17025, ensuring authoritative calibration results and global mutual recognition.
6. Technological Continuity and Investment Protection: As a classic technology with a long lifecycle, it remains viable without obsolescence due to technological iteration, making it a worthwhile long-term investment asset.
Core Application Areas
Metrology Calibration Institutions: Provincial and municipal metrology institutes and laboratories for pressure value transfer and traceability, establishing public measurement standards
