Section 1 Product overview The Intellical PHC101 series pH probes are digital, combination electrodes that measure the pH of wastewater, drinking water and general water samples. The probes have a non-refillable, gel-filled electrolyte and a built-in temperature sensor. The open reference junction gives an optimum electrical connection between the sample and the electrolyte and does not become clogged.

3.2 Use of hazard information D A N G E R Indicates a potentially or imminently hazardous situation which, if not avoided, will result in death or serious injury. W A R N I N G Indicates a potentially or imminently hazardous situation which, if not avoided, could result in death or serious injury.
1. Remove the protective tape from the reference junction. Refer to Figure 2. Rinse the reference junction and glass bulb with deionized water. Blot dry with a lint-free cloth. 3. For faster stabilization, soak the probe for 3 or more minutes in the sample before use. 4.
• Calibrate the probes and verify the calibration regularly for best results. Use the meter to set calibration reminders. • The calibration data is stored in the probe. When a calibrated probe is connected to a different meter with the same calibration options, a new calibration is not necessary. •...
Section 6 Sample measurement The procedure that follows is applicable to meters that can connect to Intellical pH probes. Refer to the applicable meter documentation for meter operation and probe-specific settings. 6.1 Sample measurement notes Read the notes that follow before sample measurements. •...
5. Stir gently, then read the pH value of the sample. The display shows the temperature- compensated pH value when the reading is stable. Section 7 Verify the calibration Measure the pH value of a fresh pH buffer solution to make sure the result is accurate. The meter compares the selected pH buffer value to the measured pH value and accepts or rejects the measurement.
5. Shake the probe 6. Stir gently, then from side to side to read the pH value of refresh the reference the buffer solution. junction and remove The meter accepts air bubbles. or rejects the result. Section 8 Maintenance Regular maintenance is necessary for the best accuracy, stabilization time and life of the probe. Keep the probe in the recommended storage solution between measurements.
N O T I C E Probes can become permanently damaged if kept in a storage solution that is not specified by the manufacturer. Use only the specified storage solution (Hach pH electrode storage solution or 3 M KCl). Do not store the probe in deionized water or in samples of low ionic strength. Put the soaker bottle that contains the storage solution on the probe when not in use.
Figure 6 Probe storage Section 9 Troubleshooting Keep the probe clean and in the recommended storage solution when not in use for the best accuracy, stabilization time and life of the probe. Problem Possible cause Solution Decreased probe performance The glass sensor is dirty. Clean and condition the probe.
