Recently, the 2026 4th Supply-Demand Matching Conference on Domestic Substitution of Process Industry Instrumentation Equipment was grandly held in Zibo, where the Catalogue of Domestic Substitute Instruments for the Petrochemical and Chemical Industry (2026) was officially released. For the second consecutive year, Shanghai Chenzhu Instrument Co., Ltd. has been listed in the Catalogue, supported by 100% in-house R&D and a 100% domestically sourced product portfolio, continuing to contribute the "Chenzhu strength" to achieving independent and controllable industrial and supply chains!
The conference focused on the independence and self-reliance of key instrumentation equipment for the process industries, bringing together industry experts, design institutes of central state-owned enterprises, large chemical companies, and instrument manufacturers to discuss pathways for domestic substitution — playing an important role in strengthening the security of industrial and supply chains.
The Catalogue of Domestic Substitute Instruments for the Petrochemical and Chemical Industry (2026 Edition) targets the core need for independent and controllable industrial and supply chains. It systematically compiles mature, high-quality domestic products in key industries, providing a practical reference for mitigating "chokepoint" risks in critical fields and consolidating the foundation of industrial security.
Consecutive Selection — "Chenzhu Strength" Recognized Again
Through the open solicitation, enterprise application, qualification review, and expert evaluation procedures organized by the Process Industry Branch of the China Association for Mechatronics Technology and Application, Shanghai Chenzhu's core products have once again been included in the Catalogue, including isolated safety barriers, signal isolators, surge protective devices, safety relays, and HART multiplexers.
This is the second consecutive selection of Shanghai Chenzhu's core products, following the 2025 edition — continuing to contribute the "Chenzhu strength" to achieving independent and controllable industrial and supply chains!
APL Integrated Solution Showcased On-Site
At the conference, Chenzhu presented a demonstration unit of its “NIICA over APL — Intrinsically Safe, Explosion-Protected and Lightning-Protected APL Integrated Solution” , engaging in in-depth exchanges with industry experts and users, and sharing Chenzhu's latest explorations and practices in automation safety technology.
