The SUP-pH6002 eliminates this failure mode by utilizing a large-surface-area annular PTFE (Teflon) liquid junction paired with a chemically inert glass outer tube. With an integrated PT1000 RTD directly in the shaft, it provides instantaneous temperature compensation to your transmitter, extending calibration intervals and protecting against measurement drift in high-fouling environments.\u003c\/blockquote\u003e\n\u003ch3\u003eWhy the Annular PTFE Junction Matters to Operators\u003c\/h3\u003e\n\u003cp\u003eMost industrial pH sensor failures are not failures of the glass measuring electrode; they are failures of the reference junction. When a single ceramic wick becomes coated in heavy sludge, oil, or chemical precipitates, the ionic path between the internal reference cell and the process liquid is severed. This causes the transmitter to display erratic readings, slow response times, or impossible calibration slopes.\u003c\/p\u003e\n\u003cp\u003eThe SUP-pH6002 utilizes a full-ring \u003cb\u003eannular PTFE junction\u003c\/b\u003e surrounding the pH glass bulb. PTFE is naturally hydrophobic and chemical-resistant, which dramatically reduces the adhesion of organic residues, fats, and industrial particulates. This large surface area ensures that even if a portion of the sensor is exposed to direct fouling, a stable electrical circuit is maintained with the reference system, drastically reducing the frequency of unscheduled maintenance.\u003c\/p\u003e\n\u003ch3\u003eKey Performance Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cb\u003eIntegrated PT1000 Temperature Compensation:\u003c\/b\u003e Eliminates the need for a separate thermowell or external temperature probe. The PT1000 RTD sits close to the measuring glass, providing the transmitter with high-resolution, low-drift temperature data for precise, real-time Nernst slope correction up to 100°C.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eChemically Inert Glass Body:\u003c\/b\u003e Unlike polymeric cases (such as ABS or polycarbonate) which can suffer from solvent swelling, chemical attack, or early thermal degradation, the borosilicate glass outer tube provides near-universal chemical compatibility and structural stability under high-temperature processes.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eAg\/AgCl Double-Junction Reference:\u003c\/b\u003e Utilizes a robust silver\/silver chloride reference system.

Technicians must use adequate thread seal tape (PTFE) on the PG13.5 threads during pipe or immersion installs to prevent process fluid from wicking up and short-circuiting the cable connection.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eStorage Best Practices:\u003c\/b\u003e The glass measuring bulb and reference junction must remain hydrated. If removed from the process line, the sensor must be stored in the protective cap filled with 3.3 M KCl (potassium chloride) solution. \u003ci\u003eNever store the sensor in distilled or deionised water,\u003c\/i\u003e as this will rapidly leach ions from the glass membrane and permanently damage the electrode's response slope.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable width=\"100%\"\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth align=\"left\"\u003eParameter\u003c\/th\u003e\n\u003cth align=\"left\"\u003eOperational Specification\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cb\u003eMeasurement Range\u003c\/b\u003e\u003c\/td\u003e\n\u003ctd\u003e0 to 14 pH\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cb\u003eZero Potential Point\u003c\/b\u003e\u003c\/td\u003e\n\u003ctd\u003eEo = 7.00 pH (±0.5 pH)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cb\u003eIntegrated RTD\u003c\/b\u003e\u003c\/td\u003e\n\u003ctd\u003ePT1000\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cb\u003eProcess Temperature Range\u003c\/b\u003e\u003c\/td\u003e\n\u003ctd\u003e0 to 100°C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cb\u003eMaximum Pressure Resistance\u003c\/b\u003e\u003c\/td\u003e\n\u003ctd\u003e≤0.6 MPa (6 Bar) at 25°C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cb\u003eReference System\u003c\/b\u003e\u003c\/td\u003e\n\u003ctd\u003eAg\/AgCl with solid dielectric and long-distance diffusion path\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cb\u003eLiquid Junction Type\u003c\/b\u003e\u003c\/td\u003e\n\u003ctd\u003eLarge-area annular PTFE (Teflon)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cb\u003eElectrode Shaft Material\u003c\/b\u003e\u003c\/td\u003e\n\u003ctd\u003eBorosilicate Glass\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cb\u003eDimensions\u003c\/b\u003e\u003c\/td\u003e\n\u003ctd\u003eφ12 x 120 mm standard (diameter x immersion length)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cb\u003eMounting Thread\u003c\/b\u003e\u003c\/td\u003e\n\u003ctd\u003ePG13.5 (international standard)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cb\u003eCable Assembly\u003c\/b\u003e\u003c\/td\u003e\n\u003ctd\u003e5-metre standard, shielded low-noise instrument cable\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cb\u003eCertification \u0026amp; Compliance\u003c\/b\u003e\u003c\/td\u003e\n\u003ctd\u003eCE, RoHS, ISO 9001\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"Supmea","offers":[{"title":"Default Title","offer_id":47129377374379,"sku":"ICP-PAG-370-E50-PT1K","price":500.0,"currency_code":"NZD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0635\/6385\/8091\/files\/SupmeapH-6002_2.png?v=1779839242","url":"https:\/\/www.instore.nz\/products\/supmea-sup-ph6002-glass-body-industrial-ph-sensor","provider":"inStore Ltd","version":"1.0","type":"link"}
