Welcome to Huzhou Accuracy Instrument CO LTD, a premier destination for industrial mechanical measurement excellence. We are professionally engaged in the development, sales, and service of industrial mechanical pressure gauges, bi-metal thermometers, SF6 manometers, and hybrid gas density monitors.
As a leading China Hybrid Gas Density Monitor Manufacturer, our facility spans 3,000 square meters, integrating twenty years of research and production expertise. Our systems are critical for Mechanical Engineering, Chemical Engineering, and high-technology electric appliances, ensuring the safety of global power grids.
Our China-based factories offer a complete supply chain from raw stainless steel sourcing to precision laser welding. This reduces lead times and ensures unmatched cost-efficiency without sacrificing the ±0.5% precision required for SF6 gas monitoring.
Our R&D department of 20 specialists focuses on Smart Sensor Integration. Unlike traditional mechanical gauges, our Hybrid Gas Density Monitors combine mechanical dials with electronic signal outputs (4-20mA/RS485), providing dual-layer safety.
We adhere to strict international standards including ISO 9001:2008, CE, and SGS certifications. Every unit undergoes 100% pressure cycle tests and environmental simulations to ensure "zero-leak" performance in extreme climates.
The global energy sector is transitioning toward Smart Grids. The traditional method of manual gas checking is being replaced by real-time digital monitoring. Hybrid Gas Density Monitors serve as the bridge in this evolution.
Optimized for GIS (Gas Insulated Switchgear). Our monitors prevent catastrophic failures by detecting trace SF6 leaks before insulation levels drop below critical thresholds.
As the industry explores N2/SF6 mixtures or new eco-gases, our hybrid sensors are calibrated for multi-gas density curves, ensuring future-proof infrastructure.
Ideal for unmanned stations. The electronic output allows for remote SCADA integration, reducing maintenance costs by up to 40% compared to periodic manual inspections.
Our laboratory conducts rigorous testing adhering to ISO 9001 and ISO 17025 standards. We understand the high stakes of power distribution, which is why we offer a one-year warranty and 24/7 technical support.
ISO Certification
CE Compliance
Quality Assurance
A: The hybrid version provides both local visual indication (dial) and remote electronic signals (RS485/Modbus). This allows for continuous data logging and early warning systems in smart grid applications.
A: Yes. Our products are designed with IP65/IP67 waterproof ratings and use temperature-compensated mechanisms to ensure accuracy from -40°C to +60°C.
A: Absolutely. As a direct China factory, we can customize dial faces, connection threads (NPT, G, M), signal outputs, and brand logos to meet specific project requirements.
A: For standard specifications, our lead time is usually 2-3 weeks, thanks to our annual output capacity of over 2 million units.
