ELECTRODE CONDITIONING
AND MAINTENANCE
PREPARATION
Remove the protective cap.
DO NOT BE ALARMED IF SALT DEPOSITS ARE PRESENT. This is normal
with electrodes and they will disappear when rinsed with water.
During transport tiny bubbles of air may form inside the glass bulb
affecting proper functioning of the electrode. These bubbles can be
removed by "shaking down" the electrode as you would do with a
glass thermometer.
If the bulb and/or junction is dry, soak the electrode in HI 70300
storage solution for at least one hour.
pH VALUES AT VARIOUS TEMPERATURES
Temperature has an effect on pH. 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.
For instance, if the buffer temperature is 25°C, the display should
show pH 4.01, 7.01 or 10.01 at pH 4, 7 or 10 buffers, respectively.
At 20°C, the display should show pH 4.00, 7.03 or 10.06. The meter
reading at 50°C will then be 4.06, 6.98 or 9.82.
Note: to prevent damage to the electrode, remove the pH electrode
from the solution before turning the meter off.
If the meter is OFF, detach the electrode from the meter before
immersing the electrode in the storage solution.
