The replaceable probe design means you never need to replace the entire meter—just swap the SP-C3 sensor when needed. Factory calibration for pH, EC, and TDS ensures accuracy out of the box, while digital recalibration keeps your meter precise over years of use.\u003c\/p\u003e\u003ch3\u003eMaintenance \u0026amp; Care:\u003c\/h3\u003e\u003cp\u003eRinse the probe with distilled water after each use and store with the cap filled with pH storage solution to maintain electrode hydration. Recalibrate pH monthly or when readings drift. The replaceable SP-C3 probe typically lasts 12-18 months with proper care. Replace batteries when the low-battery indicator appears.\u003c\/p\u003e\u003cp\u003e\u003cem\u003eNote: 442™ is a registered trademark of Myron L Company.
