Yewhick EC/TDS meters are calibrated using standard conductivity solutions (e.g., 1413 µS/cm or 12880 µS/cm). The process typically involves rinsing the probe, immersing it in the calibration solution, and pressing a calibration button. Detailed steps are in your manual.

Always store your pH probe in pH storage solution (or pH 4.00 buffer if storage solution is unavailable) to keep the sensor hydrated. EC/TDS probes should be kept clean and typically stored dry or as recommended in the manual.

Inaccurate readings often indicate the need for calibration, a dirty probe, or a probe that has dried out. Ensure proper calibration, clean the probe, and verify it's stored correctly. If issues persist, the probe may need replacement.

Many Yewhick models feature robust, splash-proof designs suitable for the humid conditions of grow rooms. Please check the specific IP rating for your chosen model in its product specifications.

For pH meters, you'll need pH 4.00, pH 7.00, and potentially pH 10.00 buffer solutions. For EC/TDS meters, you'll need standard conductivity solutions (e.g., 1.413 mS/cm or 12.88 mS/cm).

Yes, most Yewhick hydroponics meters are equipped with ATC to ensure that your pH, EC, and TDS readings are accurate regardless of the solution's temperature, providing reliable data for precise adjustments.
