Execution Standards: European NT Build 492, GB/T 50082-2024 "Standard for Test Methods for Long-Term Performance and Durability of Concrete", SL/T 352-2020 "Code for Test Methods of Hydraulic Concrete", GB/T 31289-2014 "Marine Silicate Cement", (T/CBMF 37-2018) (T/CCPA 7-2018) UHPC "Basic Properties and Test Methods of Ultra-High Performance Concrete", GB/T 42272-2022 "Test Method for Chloride Diffusion Coefficient of Cement Paste"

2020 stabilized version, integrating the RCM method of the French and Chinese standards, the NEL method of the cement national standard, and the UHPC standard with four algorithms into one unit. The 2020 stabilized version of the chloride ion diffusion coefficient RCM/NEL tester independently developed by Beijing Naierde Company utilizes an independently developed automatic voltage regulation system, which can automatically output stable high-precision voltage and achieve high-precision current, ensuring better measurement accuracy of the equipment; all voltage levels exceed the standard requirements. The 8-inch touch screen offers a user-friendly human-machine interface, and the test fixtures are made of imported high-purity acrylic material, which is colorless, transparent, and highly corrosion-resistant. The all-in-one machine with multiple methods has powerful functions, featuring an automatic data collection and control system; its measurement accuracy meets and exceeds national standards, making it an optimal choice for quality inspection units and research institutions.
