From "Warmth in Spring Waters" to Standard Dissemination | Warm Congratulations on the Successful Conclusion of the National Temperature Metrology Technical Specifications Promotion Conference

"Three or two peach blossoms beyond the bamboo, ducks know first when spring waters warm." In this vibrant March, the National Temperature Metrology Technical Specifications Promotion Conference successfully concluded on the 27th in Taizhou, Jiangsu Province.

Conference Review

Chaired by Chen Weixin, Secretary-General of the National Temperature Metrology Technical Committee, the event featured training sessions covering four newly released metrology technical specifications, complemented by theoretical exams and practical assessments. During the specification interpretation segment, four principal drafters—Zhao Jing (China Institute of Testing Technology), Jin Zhijun (National Institute of Metrology, China), Chen Danying (Fujian Institute of Metrology), and Zhu Yichen (Shanghai Institute of Measurement and Testing Technology)—provided detailed explanations of:

• JJF 2189-2025 Calibration Specification for Precision Thermometers Used with Platinum Resistance Thermometers

• JJF 2143-2024 Calibration Specification for Temperature Parameters of Microwave Digestion Systems

• JJF 2168-2024 Calibration Specification for Salt Spray Test Chambers

• JJF 1183-2025 Calibration Specification for Temperature Transmitters

For the practical assessment phase, our company supplied specialized equipment and technical teams aligned with JJF 2168-2024 Salt Spray Test Chamber Calibration Specification and JJF 1183-2025 Temperature Transmitter Calibration Specification. Notably, the nano-volt micro-ohm thermometer we provided at the venue exceeded the requirements outlined in JJF 2189-2025, earning high praise from attending experts and industry peers.

This training not only deepened industry professionals' understanding of the newly released specifications but also reinforced calibration expertise through hands-on evaluations. Moving forward, our company will continue to monitor developments in metrology, actively participate in promoting and implementing relevant standards, and contribute to the high-quality advancement of the industry.
