Calibrating With the Buffer Sachets
For a two-point calibration, start with the pH 7.01 buffer and then use pH 4.01 for acidic samples or pH 10.01 for alkaline ones. Each 20 ml sachet is opened for one calibration, so the buffer is fresh each time and there is no stock bottle for a dirty electrode to contaminate. Rinse the electrode with distilled water between buffers and before each sample.
Electrode Range and Care
The display covers 0 to 14 pH, but the HI 1271 electrode is rated for 0 to 13 pH and 0 to 50 °C, so readings beyond those limits are outside what the electrode is meant for. Between uses, keep the electrode tip wet with the preservative solution rather than storing it dry or in distilled water. When a worn electrode no longer calibrates, the spare HI 1271 fits straight onto the tester.
