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.
