Introduction
HI931 fully automatic potentiometric titrator is specially used for laboratory titration analysis. It is a customizable analyzer that can provide accurate analysis results and has a good user experience. Supports acid-base titration, anhydrous titration, redox titration, precipitation titration, complex titration and other titration types. The instrument provides a variety of measurement methods (can store 100 titration methods, including the instrument's own methods and user-defined methods ), one-click titration, and can also directly read and perform back-titration on complex samples. For the automated settings of the instrument, the HI931 titrator can be used in conjunction with the HI922 automatic sampler to automatically add reagents and automatically convert samples, so that accurate results can be obtained in less time.
