FUNCTIONAL DESCRIPTION SPECIFICATIONS Range 0.00 to 14.00 pH / ±1999 mV Resolution 0.01 pH / 1 mV Accuracy (@20°C) ±0.01 pH / ±1 mV Typical EMC Deviation ±0.03 pH / ±2 mV pH Calibration Manual, 2 point, through offset and slope knobs Temperature Compensation Manual, from 0 to 100°C (32 to 212°F) pH Electrode (included) HI 1048B glass body, double junction, refillable, with BNC and 1 m (3.
OPERATIONAL GUIDE Power connection Plug the 12 Vdc adapter into the power supply socket (#9 on page 4). Note: Make sure the main line is protected by a fuse. • Press the pH key to display the pH measurement. • The display shows the pH value of the test solution compensated for temperature. Electrode connection For pH or ORP electrodes with internal reference, connect the electrode to the BNC socket on the rear panel (#10 on page 4).
pH CALIBRATION IMPORTANT • Press the pH key to select pH measurement. For better accuracy it is recommended to calibrate the instrument frequently. Calibration should be performed whenever the pH electrode is replaced, after performing a cleaning procedure or changing the reference electrolyte, and at least once a month. • Wait a couple of minutes, then adjust the OFFSET knob until the display shows the pH value at the noted temperature (see the "pH versus temperature" chart at page 10).
pH VALUES AT VARIOUS TEMPERATURES pH ELECTRODE MAINTENANCE pH readings are strongly affected by temperature. The calibration buffer solutions are affected by temperature changes to a lesser degree than normal solutions. For manual temperature calibration please refer to the following chart. Note: To prevent damage to the electrode, remove the pH electrode from the sample before turning the meter off. With the meter OFF, detach the electrode from the meter and immerse it in the storage solution.
Cleaning procedure After use, clean the electrode by immersing it in the proper cleaning solution (HI 700635 or HI 700636) for 5 minutes. If case of slow and unreliable readings, it is recommended to perform the following procedure for cleaning the junction: 1. Shift upwards the PTFE collar. If the collar does not shift easily, immerse it into warm water. 2. Wipe gently the electrode surface with a soft and clean tissue. 3.
