Heavy-duty sensors, transducers, and pressure gauges engineered specifically for Kashagan oilfields, Karachaganak gas processing, and extreme winter infrastructure.
Kazakhstan stands as the dominant industrial powerhouse of Central Asia. With extensive oil and gas operations across the Caspian basin (Tengiz, Kashagan, Karachaganak), vast metallurgical complexes in Karaganda and Pavlodar, and rapidly modernizing urban utility grids in Almaty and Astana, the demand for high-reliability process instrumentation accessories has reached an unprecedented peak.
Operating in Kazakhstan presents a unique set of engineering challenges. Process accessories—including pressure transmitters, capillary thermometers, diaphragm seals, and electric contact gauges—must withstand severe sub-zero temperatures (dropping below -45°C during harsh winter cycles) and aggressive ambient atmospheres laden with hydrogen sulfide (H₂S) and saline sea fog.
20 YEARS OF EXPERIENCE AND RESEARCH
Huzhou Accuracy Instrument CO LTD is professionally engaged in the development, sales, and service of industrial mechanical pressure gauges, bi-metal thermometers, SF6 manometers, and advanced pressure sensors. Products are widely used across Kazakhstan and global markets in mechanical engineering, chemical processing, food industry, pharmaceuticals, and high-technology electrical systems.
Established over two decades ago, our pressure gauge manufacturing facility spans 3,000 square meters, equipped with automated production lines, laser welding cells, and rigorous quality control systems. As an industry leader, we integrate innovation with precision engineering to deliver reliable measurement accessories for demanding projects.
R&D Department (20 Specialists): Focuses on material innovation, smart sensor integration, low-temperature compensation, and compliance with international standards (e.g., ISO, API).
Production Workforce (120 Technicians): Utilizes automated assembly, clean-room sensor packaging, and automated laser calibration to guarantee structural integrity.
Sales & Service Unit (15 Professionals): Delivers 24/7 technical consultation, rapid OEM prototyping, and localized logistics support across Central Asia.
Annual output exceeds 2 million units, encompassing stainless steel gauges, black iron steel gauges, shock-proof liquid-filled gauges, SF6 density monitors, capillary thermometers, and diffused silicon sensors.
Exported worldwide to over 30 countries, earning long-term OEM partnerships with global engineering firms due to our strict ±0.5% full-scale precision and extreme corrosion resistance.
Our testing laboratory conducts 100% pressure cycling tests, high-overpressure burst validation, and environmental climate chamber simulations in accordance with ISO 9001 and ISO 17025 standards.
Continuous continuous refinement backs our market reputation for zero-leak performance under severe vibration, pulsation, and thermal shock, supported by a full 1-year replacement warranty.
We strictly adhere to "reasonable price, accurate delivery, and superior quality." Production quality consistently exceeds global benchmarks under ISO 9001:2008 standards.

| Ingress & Explosion Rating | IP65 Standard | IP67 / IP68, Ex d IIC T6 Gb / Ex ia IIC T4 Ga | Hermetically sealed housings designed for explosive hazard zones. |
| Output & Protocols | 4-20mA / 0-10V Analog | 4-20mA HART 7.0 / Modbus RS485 / SIL-2 | Seamless digital integration into local SCADA and Honeywell/Emerson DCS. |
Unlike traditional glued strain gauges that degrade under thermal cycling, our thin-film pressure sensors use molecular beam sputtering to bond inorganic strain gauges directly to a stainless steel diaphragm at a molecular level. This results in unprecedented hysteresis performance (<0.1% FS) and zero thermal fatigue when exposed to Kazakhstan's day-to-night temperature fluctuations.
For chemical and petrochemical applications, our accessories feature laser-welded diaphragm seals filled with specialized silicone or synthetic oils rated down to -55°C. The seal completely isolates sensitive internal elements from viscous, crystallization-prone, or highly caustic line media common in heavy oil extraction.
