Dead Weight Tester Offering Exceptional Reliability and Stability for Accurate Pressure Calibration and Measurement Tasks

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.
