On September 6, 2021, the company obtained the nim-cs certificate issued by China Institute of Metrology (China OIML certificate issuing authority), and became one of the first enterprises in the domestic water meter industry to obtain this certificate, which also marks that the company's products have been recognized by the authority of the country's highest metrological technology institution.
At present, China Academy of metrology is the only oiml-cs (OIML certification system) certification institution approved by the international legal metrology Organization (OIML).The measurement evaluation certificate system for measuring instruments (nim-cs) is led by the Chinese Academy of Metrology and jointly with relevant units, relying on the quality framework system of China OIML certificate issuing authority (oiml-cs) and in accordance with relevant international standards, international recommendations, national standards, industrial standards and national specificationsThe measurement system carries out all-round and systematic measurement test and evaluation, and provides "physical examination certificate" for internal quality control, "letter of credit" and "pass" for external brand promotion and market promotion for measurement instruments and instrument manufacturers.
In this measurement test, the non-magnetic sensing wireless remote transmission cold water meter independently developed by the company is based on JJF 1777-2019 outline for type evaluation of drinking cold water meters, GB / T 778.1-2018 drinking cold water meters and hot water meters Part 1: measurement requirements and technical requirements, and GB / T 778.2-2018 drinking cold water meters and hot water meters Part 2: Test methodsThe external structure, sign, water temperature and temperature grade of water meter are 5 categories and 23 sub categories. The results show that all items are qualified and meet the requirements!
