[China Instrument Network Instrument R&D] Recently, the automatic potentiometric titrator verification device of the Chemical and Environmental Measurement and Inspection Department of the Wuxi Metrology and Testing Center successfully passed the on-site assessment of the provincial bureau, and was upgraded from the original sub-standard to the high standard, and the verification capability was further improved. The improvement.
Automatic potentiometric titrator is designed according to the principle of potentiometric titration, is a common capacity analyzer, mainly used in acid-base titration, redox titration, precipitation titration, complexometric titration. Due to its wide range of applications, 99% of the chemical laboratories have instruments such as automatic potentiometric titrators, so the automatic potentiometric titrator verification device is responsible for a large number of mass transfer tasks.
Through this standard upgrade, the accuracy level of the automatic potentiometric verification device's electricity meter has been increased from the original 0.02 level to 0.0006 level, and the verification items that can be carried out have been upgraded from the original 0.1 level and below to 0.05 level and below.
In recent years, the Wuxi Metrological Verification Testing Center has focused on the improvement of metrology and inspection technology, and has undertaken the establishment of the highest metrological standards and social public metrology standards within the city's administrative divisions, conducted quantitative transfer, enforcement of mandatory tests, and other verification and testing tasks prescribed by law. At the same time, it provides the society with maintenance and calibration services for measuring instruments.
The successful passing of the automatic potential potentiometer verification device at the secondary standard raised the spotlight, which reflects Wuxi's metrological verification testing center advancing with the times and constantly improving its detection capabilities, and has also increased the customer's satisfaction with the center's capabilities.
