Horiba 3-in-1 Combination pH Electrode with Built-in Temperature Sensor Model:9652-10D - Gel Combination pH Electrode, Black, 1 m Cable - 3200786359 The correct cleaning reagent willHORIBA 3 in 1 combination pH electrodes contain the pH sensing glass, the reference half cell and a temperature sensor in a single body. Because temperature is measured at the same point as pH, the meter applies automatic temperature compensation without a separate probe one connector, one electrode, correctly compensated readings. This is the range to choose from when your meter supports automatic temperature compensation. Below, the models are
