Proper Care & Maintenance:
To maintain the performance and extend the lifespan of your PH51 pH tester, follow these essential care tips:
- Rinse after use: Always rinse the electrode with distilled water after testing to avoid residue buildup and cross-contamination.
- Store correctly: Keep the probe moist using proper storage solution inside the cap. Avoid letting the electrode dry out.
- Calibrate regularly: Perform calibration frequently, especially if testing across a wide pH range or in critical applications. Use fresh buffer solutions (typically pH 7.01 and 4.01 or 10.01).
- Replace probe when needed: When readings become unstable or response time slows, consider replacing the MA73600 probe to restore accuracy.
- Avoid extreme temperatures: Store and use the tester within recommended temperature ranges to prevent damage to the probe and electronics.
