BD-7600-A72 Coulometric Trace Water Analyzer
The BD-7600-A72 coulometric trace water analyzer employs the classic Karl Fischer microcoulomb method. Based on electrolysis principles, the instrument detects the number of charges (coulombs) involved in the reaction and automatically converts this into corresponding water content measurements. This method delivers high testing accuracy with low operational costs, reliably measuring trace moisture in liquid, gas, and solid samples.
Featuring high sensitivity, precision, and reproducibility with low power consumption and energy-saving design, the analyzer includes a built-in battery for portable measurements. It is widely used across petroleum, chemical, power, pharmaceutical, commodity inspection, scientific research, and environmental protection industries.
