4120(W) / 4130(W) General information General information Automatic sensor The sensor electronics with the stored sensor data are in the connecting recognition head of the electrode. The data include, among other things, the sensor type and series number. In addition, the calibration data are stored in the sensor with each calibration and the calibration history is recorded (the last 10 cali- brations).

Storage 4120(W) / 4130(W) measurement to the next by taking the following measures: – Shortly rinse the calibration and sample beakers with the solution the beakers are to be filled with next. – Between measurements, rinse the electrode with the solution that fol- lows.
4120(W) / 4130(W) Aging NOTE pH electrodes must not be stored dry or in deionized water. The elec- trode could be permanently damaged by this. If the liquid in the watering cap has dried up, condition the electrode in reference electro- lyte (KCl 3 mol/l, Ag+ free) for at least 24 hours.
Technical data 4120(W) / 4130(W) Cleaning Remove water-soluble contamination by rinsing with deionized water. Remove other contamination as follows: Contamination Cleaning procedure Fat and oil Rinse with water containing household wash- ing-up liquid Lime and hydroxide deposits Rinse with citric acid (10 % by weight) NOTE Hydrofluoric acid, hot phosphoric acid and strong alkaline solutions destroy the glass membrane.
