To calibrate the PH100 Meter, first prepare a pH 7.0 buffer solution. Turn on the meter, immerse the electrode in the solution, and adjust the calibration knob until the display reads 7.0 pH. Repeat the process with a pH 4.0 or pH 10.0 buffer for a two-point calibration.
Erratic readings can be caused by a dirty or damaged electrode. Clean the electrode with distilled water and a soft brush. Ensure there are no air bubbles trapped in the electrode. If the issue persists, replace the electrode.
Store the electrode in a storage solution or a pH 4.0 buffer solution to keep it hydrated. Avoid storing in distilled water as it can damage the electrode. Always keep the electrode cap on when not in use.
Regularly clean the electrode with distilled water and a soft cloth. Calibrate the meter periodically to ensure accuracy. Check the battery level and replace it as needed. Store the meter and electrode properly when not in use.
To replace the battery, turn off the meter, and open the battery compartment. Remove the old battery and insert a new one, ensuring the correct polarity. Close the compartment securely.
If the meter does not turn on, check the battery for charge and ensure proper placement. If the battery is fine, inspect the battery contacts for corrosion and clean them if necessary.
The PH100 Meter is designed primarily for aqueous solutions. Measuring non-aqueous solutions may require a specific electrode suitable for such measurements to ensure accurate readings.
Replace the electrode if it fails to calibrate correctly, shows sluggish response, or provides inaccurate readings even after cleaning and calibration.
The electrode's lifespan typically ranges from 1 to 2 years, depending on frequency of use and maintenance practices. Proper care can extend its life.
Clean the meter's body with a soft, damp cloth. Avoid using harsh chemicals or submerging the meter in water, as this can damage its electronics.
