To calibrate the Flir Extech PH113, use the included calibration solutions. Start with the pH 7.0 buffer solution, followed by the pH 4.0 or pH 10.0 buffer solution, depending on the range of pH you expect to measure. Ensure the sensor is clean before calibration.
If your pH readings are inconsistent, ensure the electrode is properly cleaned and calibrated. Check for any air bubbles trapped inside the electrode, which can affect readings. Replace the electrode if necessary.
The electrode should typically be replaced every 1 to 2 years, depending on usage and storage conditions. Regular calibration and maintenance can extend the electrode's life.
The Flir Extech PH113 is designed for aqueous solutions. For non-aqueous solutions, ensure compatibility and consider using a specialized electrode that is designed for such measurements.
Regular maintenance includes rinsing the electrode with distilled water after use, storing it in a storage solution, and calibrating it regularly. Avoid letting the electrode dry out.
Store the electrode in a storage solution or pH 4.0 buffer solution. Ensure the electrode is capped to prevent it from drying out, which can damage the sensor.
A slow response time may be caused by a dirty or clogged electrode. Clean the electrode thoroughly and ensure it is properly hydrated. Re-calibrate after cleaning.
For optimal accuracy, perform measurements at room temperature. Temperature fluctuations can affect pH readings. Most pH meters have automatic temperature compensation to adjust for minor temperature variations.
Refer to the user manual for specific error codes. Common solutions include recalibrating the meter, checking electrode connections, and replacing the electrode if it is faulty.
Use a mild detergent solution to clean the electrode, followed by rinsing with distilled water. For stubborn contamination, use a specialized electrode cleaning solution. Re-calibrate the electrode after cleaning.
