To ensure accuracy in demanding environments, the electrode utilizes a PTFE reference junction and a titanium liquid earth to minimize electrostatic interference and chemical polarization. The sensing element is designed for high chemical resistance, effectively suppressing signal drift and cross-talk suppression in high-ion-concentration media. The inclusion of the Pt1000 element allows for real-time temperature compensation, critical for maintaining Nernstian slope integrity across fluctuating process temperatures.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Is the SC25V-ALP25-120 suitable for hazardous area installations?\u003c\/p\u003e\n\u003cp\u003eA: Yes, the sensor is rated for Intrinsic Safety (IS) across ATEX, IECEx, and FM (US\/CAN) standards, provided it is connected to a certified safety barrier appropriate for the specific zone classification.\u003c\/p\u003e\n\u003cp\u003eQ: How does the titanium liquid earth benefit the measurement?\u003c\/p\u003e\n\u003cp\u003eA: The liquid earth provides a stable reference potential for the sensor, neutralizing stray currents within the liquid stream that would otherwise introduce significant measurement noise or rapid reference junction degradation.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eEnsure the electrode is installed at a 15-degree angle or greater from the horizontal to prevent air bubbles from accumulating on the glass membrane, which can induce erratic readings.\u003c\/li\u003e\n\u003cli\u003eUtilize the Variopin connector for a high-integrity, moisture-resistant signal path; ensure the mating cable connector is clean and dry during installation.\u003c\/li\u003e\n\u003cli\u003eVerify that the O-ring seals (Viton\/EPDM) are lubricated and seated correctly to prevent bypass leakage and moisture ingress into the connector housing.\u003c\/li\u003e\n\u003cli\u003eCalibrate the sensor using standard buffer solutions after installation to establish the zero-point offset and slope baseline before subjecting the unit to process chemicals.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Yokogawa","offers":[{"title":"Default Title","offer_id":49203409748220,"sku":"SC25V-ALP25-120","price":99.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0787\/9983\/1292\/files\/SC25V-ALP25-1201.jpg?v=1781575118","url":"https:\/\/www.electronicplc.com\/products\/sc25v-alp25-120-yokogawa-ph-electrode-new-original-stock","provider":"Electronic PLC","version":"1.0","type":"link"}
