Huzhou Accuracy Instrument CO LTD is a premier global entity professionally engaged in the development, sales, and service of high-precision industrial measurement tools. With over 20 years of R&D expertise, we specialize in mechanical pressure gauges, bi-metal thermometers, and most critically, SF6 Manometers (Gas Density Monitors).
Our 3,000 sqm facility in China serves as a hub for innovation, where we integrate advanced laser calibration and automated assembly to meet the rigorous demands of Mechanical Engineering, Chemical Engineering, and the High-Voltage Electrical sector.
Sulfur Hexafluoride (SF6) is the world's most potent greenhouse gas. In high-voltage switchgear, it is indispensable for insulation. However, even a 1% leak can have massive environmental and operational impacts. Our monitors provide the "zero-leak" assurance required by modern ESG standards.
The industry is shifting from purely mechanical gauges to Hybrid Digital-Analog Monitors. By integrating electric switch contacts, our monitors enable real-time SCADA integration, allowing grid operators to predict maintenance before a failure occurs.
Whether it's the harsh winters of Northern Europe or the humid tropics of Southeast Asia, our SF6 monitors are temperature-compensated to ensure density readings (not just pressure) remain accurate across all climates.
Current focus on ±0.5% precision and laser-welded diaphragm seals to eliminate all potential leak paths within the instrument itself.
Developing RS485 and wireless LoRaWAN SF6 monitors that transmit density data directly to cloud-based monitoring platforms.
Designing instruments compatible with alternative "Green Gases" (e.g., C4-FN mixtures) as the industry moves toward SF6-free alternatives.
20 specialists focusing on material innovation and smart sensor integration. We strictly adhere to API and ISO standards to ensure global interoperability.
Our lab conducts 100% pressure cycle tests and environmental simulations. We adhere to ISO 9001 and ISO 17025 benchmarks for every unit shipped.
Professional sales unit providing 24/7 technical support. We offer customized OEM/ODM solutions tailored to specific industrial requirements.
Our production quality exceeds ISO9001:2008 benchmarks, ensuring "Reasonable Price, Accurate Delivery, and Good Quality."
SF6 pressure changes significantly with temperature while density remains constant. Our monitors use internal compensation mechanisms to ensure that the reading reflects the actual amount of gas present, preventing false alarms during cold weather.
Yes. Our CE-certified models come with adjustable electric contacts that can be set to provide low-pressure alarms or lockout signals to your control center.
We primarily use high-grade 304 or 316L stainless steel for housings and connectors, combined with laser-welded seals to withstand aggressive industrial environments.
Absolutely. We offer OEM services including custom logos, specific pressure unit scales (Bar, MPa, PSI), and color-coded safety zones on the dial.
