MI555-001 pump calibration standard is used to calibrate the dosing system of MI455 SO2 automatic mini titrator. The correct calibration of the dosing pump is needed for the accurate determination of the amount of titrant used when performing a titration. The MI455 uses a pre-programmed formula to determine the exact concentration of sulfur dioxide. The pump calibration procedure needs to be completed when the titrant or ORP electrode is replaced.
