The Fully Automatic Water-Soluble Acid Tester (Colorimetric Method) is designed and manufactured according to the national standard of the People's Republic of China, GB/T7598-2008 "Testing Method for Water-Soluble Acids in Transformer Oil in Operation" and related standards. It features a large screen liquid crystal display and utilizes microprocessor control to automatically complete functions such as heating, constant temperature, oscillation, sampling, testing, cleaning, and printing based on user-defined conditions. It can measure 1-3 samples at once, significantly reducing the user's testing time. Additionally, this instrument is equipped with a USB interface for communication with a computer.
