Gasoline moisture analyzer
Karl Fischer Coulomb method (electric quantity method)
Product details
Gasoline moisture analyzerThe SF-5 Trace Moisture Analyzer (excluding printing) uses the Karl Fischer Coulombic method (Karl Fischer coulometric method) to determine the moisture content in samples, overcoming the disadvantages of low accuracy, large electrolyte consumption, and cumbersome operation of Karl Fischer titration instruments. It utilizes advanced automatic control circuits and large electrolysis current and current automatic control technology, and the measurement results are directly displayed in digital form. The instrument has a novel and lightweight structure, and is more reliable and convenient to use. The electrolyte can be reused for a long time. It has the characteristics of fast analysis speed (one result per minute), simple operation, high accuracy, and strong automation, and is widely used in departments such as petroleum, chemical, power, railway, pesticide, medicine, and environmental protection
