GRAEFF (JIAXING) INSTRUMENT CO., LTD.

Introduction

GRAEFF (Jiaxing) Instrument Co., Ltd. (格拉夫（嘉兴）仪器仪表有限公司) is the China-based operating company associated with the GRAEFF instrumentation group, a British multinational active in pressure measurement, temperature measurement, melt-pressure sensing, and industrial control systems. Its Jiaxing operation is positioned as a manufacturing and commercial base for sensors and related instrumentation used in plastics and a wider set of process industries, with the company’s China listings and corporate materials emphasizing applications in plastics, chemical fibers, rubber, chemical processing, petrochemicals, and automation.

Within the plastics sector, GRAEFF is primarily relevant as a supplier of melt pressure sensors/transmitters, temperature sensors, and associated control and calibration equipment used on extrusion, molding, and other thermally intensive production lines. The company’s product positioning suggests a focus on process monitoring, quality stability, and industrial automation rather than on polymer production itself.

History and Development

GRAEFF’s corporate roots are presented through the broader Gräff/GRAEFF group history, which cites more than 70 years of experience in industrial temperature and measurement technology and traces the German parent company’s registration in Troisdorf to 1976. Public company materials also describe the group as international, with offices or subsidiaries in the UK, Germany, the United States, South Korea, and China.

The China company, Graeff (Jiaxing) Instruments Co., Ltd., was established in 2020 according to Chinese business-directory records, and later materials describe it as the group’s official China operating entity. The Jiaxing site is described as the company’s headquarters in China, located in Xiuzhou District, Jiaxing, Zhejiang.

A further development milestone is the company’s growing participation in industry standards and technical institutions. In 2026, GRAEFF reported that its president, Dr. Wu Hao, participated in drafting China’s national standard GB/T 47234-2026 on intelligent measurement and control equipment, indicating involvement in the formalization of industrial automation and sensor standards in China. The company has also been identified in Chinese industry reporting as having been appointed a vice-chair unit in an AI-related committee of the Jiaxing software industry association, reflecting its positioning around industrial intelligence and sensor digitalization.

Business Operations

GRAEFF’s business model centers on the R&D, production, and sales of industrial sensing and control products. In Chinese-language and English-language materials, the company describes a broad portfolio spanning pressure, temperature, flow, displacement, level, and smart sensors, along with control instruments, calibration systems, heaters, and automation control systems.

The Jiaxing company’s scope of operations, as reflected in Chinese business listings, includes:

• Intelligent instrument manufacturing
• Electrical instrument manufacturing
• Electronic component manufacturing
• Sales of intelligent and electrical instruments
• Environmental monitoring and testing instruments

The company’s public-facing materials also indicate a cross-border structure, with contact and distribution references for the United Kingdom, Germany, the United States, and South Korea, alongside China. This suggests that the Jiaxing operation functions within a wider international sales and service network rather than as a standalone local supplier.

Products and Technologies

GRAEFF’s product range is organized around industrial measurement and automation, with emphasis on the following categories:

• Pressure sensors and pressure transmitters
• Melt pressure sensors for high-temperature process applications
• Temperature sensors, including industrial temperature probes
• Flow sensors
• Displacement sensors
• Level sensors
• Pressure and temperature control instruments
• Pressure gauges
• Calibration systems
• Automation and IoT control systems

The company highlights specific technical themes that are relevant to plastics processing. One is the use of high-temperature melt pressure sensing, a critical measurement in extrusion and related polymer-processing operations where stable pressure control affects throughput, product uniformity, die performance, and equipment protection. Another is the development of NTX environmental protection type mercury-free filling high-temperature melt pressure sensors, which the company presents as a core innovation.

Public product pages also reference AI-oriented instruments such as the GAIM series AI intelligent (zero temperature drift) melt pressure sensor/transmitter, indicating a technical emphasis on reduced drift, stability, and digital integration in process environments. While the company’s detailed specifications are not fully disclosed in the available sources, its published descriptions point to a portfolio designed for continuous industrial operation in demanding thermal and chemical conditions.

• Plastics
• Chemical fibers
• Rubber
• Chemical engineering
• Petrochemicals
• Energy and power plants
• Sewage treatment
• Shipping and shipbuilding
• Environmental engineering
• Spraying equipment

• Mining and engineering machinery

For the plastics industry specifically, the company’s relevance is tied to process monitoring and control in operations such as:

• Polymer extrusion
• Melt filtration and die-pressure supervision
• Injection molding and related thermal processing
• Process automation and quality control

The company’s China exhibitor profile on ChinaPlas identifies it as having service expertise in plastics and rubber, reinforcing its direct participation in the polymer-processing supply chain. It also lists the company as a supplier in the plastics and rubber ecosystem and identifies it as a specialized, sophisticated, distinctive, and innovative enterprise recognized by Chinese government classification.

Global Presence and Market Position

GRAEFF presents itself as a British multinational company with a production and commercial footprint extending beyond China. The Jiaxing entity serves as the China manufacturing and sales base, while group materials refer to additional offices in Europe, North America, and East Asia.

In market terms, the company appears to occupy a niche within industrial sensors and process instrumentation, rather than competing as a large diversified automation conglomerate. Its product breadth, however, is notable for a specialized instrument manufacturer, and public materials cite a catalog of more than 5,000 product varieties. In plastics and adjacent processing sectors, this breadth supports applications where instrumentation choice is highly dependent on temperature range, process pressure, signal stability, and integration with control systems.

Sustainability and Environmental Initiatives

The company’s publicly stated environmental relevance is strongest in its emphasis on mercury-free melt pressure sensing technology. In the context of industrial instrumentation, mercury-free filling is consistent with broader efforts to reduce hazardous substances in equipment design and improve compliance with tightening environmental and workplace safety expectations.

GRAEFF also reports certification under ISO 45001:2018 for occupational health and safety management, covering the R&D, production, and sales of its sensor and automation products. While this is a workplace-safety standard rather than an environmental certification, it indicates formalized management systems in manufacturing operations.

The company’s inclusion in sectors such as sewage treatment and environmental engineering suggests that its instrumentation is also marketed for industrial monitoring applications that support emissions control, process efficiency, and resource management.

Financial Performance and Economic Impact

No audited public financial statements for the Jiaxing company are included in the available sources, and therefore no reliable revenue, profit, or market-share figures can be stated here. The company should be understood as a specialized industrial instrumentation manufacturer with economic impact concentrated in equipment supply, technical services, and industrial process support rather than in commodity-scale plastics production.

Its economic role is reinforced by the supply-chain nature of its business: sensors and control devices are enabling technologies that support downstream productivity, scrap reduction, process consistency, and equipment protection in plastics converting and other process industries.

Leadership and Corporate Governance

Public materials identify Wu Hao as the company’s president and as a figure involved in national-standard drafting activities in China. Company-facing records also describe the Jiaxing entity as the Chinese operating arm of a broader international group structure.

Governance-related information available in the sources is limited, but the company’s certifications, international office footprint, and participation in industry standardization indicate a formalized corporate structure with cross-border management and technical coordination.

Innovations and Future Outlook

GRAEFF’s near-term innovation themes appear to be centered on smart sensing, AI-enabled measurement, zero-drift process stability, and automation integration. These are consistent with broader industry demand in plastics manufacturing for more precise control of melt conditions, higher uptime, and improved connectivity between sensors, controllers, and digital monitoring systems.

The company’s participation in standards development suggests an interest in shaping the technical framework for intelligent measurement systems in China, which may strengthen its visibility in industrial automation markets. Its plastics-related positioning at ChinaPlas and its broad end-market coverage indicate that future growth is likely to depend on the expansion of high-precision sensing in polymer processing, chemical processing, and smart manufacturing.
