HANNA HI84531-01 Mini Titrator for Measuring Titratable Alkalinity in Water and Wastewater
The HI84531 is an easy to use, fast and affordable automatic mini titrator designed for testing titratable alkalinity levels in water. Based on an acid base titration method, this mini titrator uses an optimized pre-programmed method of analysis with a powerful algorithm that determines the completion of the titration reaction by the use of a glass body pH electrode.
The HI84531 incorporates a precision piston style dosing pump that adjusts the volume of dosing dynamically based on the voltage change. This dosing system reduces the amount of time required for the titration while providing for a highly accurate determination of the amount of titrant used.
This mini titrator is supplied complete with all the materials necessary to perform low and high range measurements of alkalinity in water. All chemicals are premixed and prepackaged including standardized titrants, reagents and pump calibration solution. There is no need for volumetric glassware or analytical balances.
