Frequently Asked Questions

Q: How often should the PH-TRA-600 electrodes be calibrated?

Calibration frequency depends on the water quality and stability. It is recommended to perform a three-point calibration regularly using 4.00, 6.86, and 9.18 buffer solutions to maintain ±0.1pH accuracy.

Q: What should I do if the display shows "ERR" during calibration?

"ERR" indicates a calibration failure. Please re-calibrate the sensor. If the error persists, the electrode may be damaged or exhausted and should be replaced with a compatible compound electrode.

Q: Can this transmitter be used in high-pressure environments?

Yes, the PH-TRA-600 electrodes are designed to handle compression resistance up to 0.5MPa and operational pressures up to 0.4Mpa, making them suitable for most industrial water pipelines.

Q: How do I prevent interference in the pH signal?

Since pH signals are weak potential signals, they must be wired separately. Ensure the signal cables do not share a protective pipe with high-voltage power supply or control wires.

Q: How to clean the PTFE sensor if it becomes polluted?

Use surface active agents for grease, 10% hydrochloric acid for calcium or metal precipitates, and a mixture of 10% hydrochloric acid with pepsins for protein adhesives.

Q: What is the best way to store the pH electrode when not in use?

Avoid storing electrodes in dry air. Clean them with water and store them in a liquid-containing case filled with 1 mol KCL solution to keep the sensor activated.
