Calibration
pH electrodes are like batteries; they run down with time and use. Because the sensitivity of a pH electrode degrades over time, it is very important to calibrate the meter to the electrode being used.
Calibration is performed using standard buffer solutions at room temperature (78°F, 25°C) buffer solutions are of a known pH and have the useful property of resisting changes in pH.
Calibration is always performed using the pH 7.00 buffer first, followed by a second calibration that is done with a buffer solution close to the anticipated pH of the solution being measured. Note: ORP does not require calibration.
Calibration Procedure
Turn the meter on.
Use the pH/mV button to select the pH mode. The unit of measure appears on the LCD.
Remove the electrode from its cap and rinse with distilled or deionized water.
Place the electrode in fresh pH 7.00 buffer solution and stir. Allow 30 seconds for the electrode/ATC to reach thermal equilibrium with the buffer solution.
Press and hold the CAL key for three (3) seconds to enter the calibration mode. The CAL display appears and then the pH value flashes on the LCD.
When the pH stops flashing, SA (save), and then END will appear in sequence.
Rinse the electrode with distilled or deionized water.
Place the electrode into the second buffer (pH 4.00 or pH 10.00) and stir. Allow 30 seconds for the electrode/ATC to reach thermal equilibrium with the buffer solution.
Press and hold the CAL key for three (3) seconds to re-enter the calibration mode. The CAL display appears and then the pH value flashes on the LCD.
When the pH stops flashing, SA (save), the Slope percentage, and then END will appear in sequence.
Note: The slope percentage is an indication of the health of the electrode. Since pH electrodes vary in performance from one to the next, this meter includes a feature that displays the electrode's slope in %. If the slope % is below 75% the electrode should be replaced (a slope of 100% is ideal).
Temperature can be the single most important component in the life of your fish. Fish, in the wild and in our aquariums, are very sensitive to changes in temperature. Learn the affects of water temperature on fish health.
As a fish hobbyist, it is imperative that you have an understanding of the water parameters that affect fish health, as well as the importance of water testing. Water testing cues you to what's happening in the system at any given time.
Often overlooked, pH may well be one of the most critical parameters in a healthy system. Maintaining the right pH range - 8.3-8.5 in marine systems - has a natural antiseptic effect, helping fish resist illness and coral calcify faster.
