· Exact measurements with a measuring range from -2.000 to +20.000 pH and an accuracy of 0.003 pH, the automated calibration with up to 5 points and the automatic buffer recognition out of 22 buffer sets. · Electrodes and user identification – safety² Every stored measuring result shows the used ID-electrode and the user. The calibration data are stored in the ID-sensor. Therefore even when using multiple ID-electrodes on the same meter, the correct calibration data is always chosen automatically. · Documentation according to GLP Protocols for the last ten calibrations and all measuring results with time and ID are available in up to 1,500 storages places. · Direct data transmission Whether conventional via RS 232 or modern via USB – both PC interfaces are integrated in the ProLab 1000. · Dead stop function The integrated dead stop function widens the field of application for manual titration jobs (e.g. wine and food industry).
