It is \u003cb\u003enot suitable\u003c\/b\u003e for high-fouling environments containing suspended solids, high-viscosity sludge, or fats\/oils. Such environments will lead to junction \"cloaking,\" resulting in increased response lag and calibration failure. Regular cleaning with dilute HCl or specialized thiourea solutions is recommended if used in heavy metal wastewater to maintain junction porosity.\u003c\/p\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\n\u003ctable width=\"100%\"\u003e\n    \u003cthead\u003e\n        \u003ctr\u003e\n            \u003cth\u003eParameter\u003c\/th\u003e\n            \u003cth\u003eSpecification\u003c\/th\u003e\n        \u003c\/tr\u003e\n    \u003c\/thead\u003e\n    \u003ctbody\u003e\n        \u003ctr\u003e\n            \u003ctd\u003eMeasuring Range\u003c\/td\u003e\n            \u003ctd\u003e0 to 14 pH\u003c\/td\u003e\n        \u003c\/tr\u003e\n        \u003ctr\u003e\n            \u003ctd\u003eAccuracy\u003c\/td\u003e\n            \u003ctd\u003e±0.1 pH\u003c\/td\u003e\n        \u003c\/tr\u003e\n        \u003ctr\u003e\n            \u003ctd\u003eZero Potential (isopotential)\u003c\/td\u003e\n            \u003ctd\u003e7 ± 0.1 pH\u003c\/td\u003e\n        \u003c\/tr\u003e\n        \u003ctr\u003e\n            \u003ctd\u003eTemperature Range\u003c\/td\u003e\n            \u003ctd\u003e0 to 90 ℃\u003c\/td\u003e\n        \u003c\/tr\u003e\n        \u003ctr\u003e\n            \u003ctd\u003eMaximum Pressure\u003c\/td\u003e\n            \u003ctd\u003e0.3 MPa\u003c\/td\u003e\n        \u003c\/tr\u003e\n        \u003ctr\u003e\n            \u003ctd\u003eMembrane Impedance\u003c\/td\u003e\n            \u003ctd\u003e\u0026lt;350 MΩ\u003c\/td\u003e\n        \u003c\/tr\u003e\n        \u003ctr\u003e\n            \u003ctd\u003eReference System\u003c\/td\u003e\n            \u003ctd\u003eAg\/AgCl \/ Gel Electrolyte\u003c\/td\u003e\n        \u003c\/tr\u003e\n        \u003ctr\u003e\n            \u003ctd\u003eLiquid Junction\u003c\/td\u003e\n            \u003ctd\u003ePin-Type Ceramic\u003c\/td\u003e\n        \u003c\/tr\u003e\n        \u003ctr\u003e\n            \u003ctd\u003eHousing Material\u003c\/td\u003e\n            \u003ctd\u003eLaboratory-grade Glass\u003c\/td\u003e\n        \u003c\/tr\u003e\n        \u003ctr\u003e\n            \u003ctd\u003eDimensions\u003c\/td\u003e\n            \u003ctd\u003e120mm length \/ 12mm diameter\u003c\/td\u003e\n        \u003c\/tr\u003e\n        \u003ctr\u003e\n            \u003ctd\u003eProcess Connection\u003c\/td\u003e\n            \u003ctd\u003ePG13.5 Thread\u003c\/td\u003e\n        \u003c\/tr\u003e\n        \u003ctr\u003e\n            \u003ctd\u003eTemperature Sensor\u003c\/td\u003e\n            \u003ctd\u003ePT1000 RTD\u003c\/td\u003e\n        \u003c\/tr\u003e\n        \u003ctr\u003e\n            \u003ctd\u003eCable Configuration\u003c\/td\u003e\n            \u003ctd\u003e5m Direct Lead (Tinned)\u003c\/td\u003e\n        \u003c\/tr\u003e\n    \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eInstallation \u0026amp; Wiring\u003c\/h3\u003e\n\u003cp\u003eThe sensor must be installed at an angle of at least 15° above the horizontal to ensure the internal buffer remains in contact with the pH-sensitive glass tip.
