The HI84432 mini titrator incorporates a peristaltic pump dosing system which allows for a highly accurate determination of the amount of titrant used. The HI84432-55U is a pump calibration standard that is used to calibrate the dosing system. A calibrated dosing pump allows for the accurate determination of the amount of titrant used when performing a titration. The amount of volume dosed along with the concentration of the titrant is used by the pre-programmed formula within the HI84432 in determining the exact acidity of fruit products. The pump calibration procedure should be performed anytime the titrant or pH electrode is replaced. Routine calibration is recommended to ensure the highest accuracy when performing a titration.
