{"product_id":"labsenreg231-combination-ph-electrode-for-wastewater-suspension-and","title":"LabSen\u0026reg;231 Combination pH Electrode for Wastewater, Suspension, and","description":"The LabSen® 231 pH electrode from Apera Instruments is manufactured using proprietary Swiss sensor technology and materials. It is specially designed for the measurement of emulsions, suspensions, effluents and samples containing protein and sulfide. The 2-pore diaphragm structure and polymer electrolyte are extremely pressure resistant and prevent solids from settling and clogging the sensing element. \u003cp class=\"\" msonormal\u003eLong-life reference system - The LabSen 231 pH electrode uses a long-life reference system consisting of a glass tube, AgCl and a reference silver wire. The top of the thin glass tube is filled with cotton, which prevents the reaction between AgCl and electrolyte when the temperature changes. It improves the stability of the reference electrode and extends the life of the electrode.\u003c\/p\u003e \u003cp class=\"\" msonormal\u003ePolymer electrolyte - The polymer electrolyte is in direct contact with the test samples without clogging the diaphragm structure. The anti-pressure capacity can reach up to 6 bar, making it ideal for measuring suspension and wastewater.\u003c\/p\u003e \u003cp class=\"\" msonormal\u003eSpecial Glass Membrane - The LabSen 231 pH electrode has a hemispherical glass membrane that is very resistant to general impact (the conventional glass bulb membrane is very fragile) and can be used in high temperature samples (up to 80 °C).\u003c\/p\u003e \u003cul\u003e \u003cli\u003epH measurement technology and material from Switzerland\u003c\/li\u003e \u003cli\u003eUnique blue hemispherical membrane\u003c\/li\u003e \u003cli\u003eNo air bubbles thanks to gel electrolyte\u003c\/li\u003e \u003cli\u003eDurable reference system\u003c\/li\u003e \u003c\/ul\u003e \u003cp class=\"\" msonormal\u003eThe electrode uses a BNC connector that is compatible with all pH meters that use BNC connectors, such as Apera Instruments PH850, PC850, PH8500, PC8500, PH700, PH910, PC910, PH950, PC950,PH800, PH800, PC800, PH820 and PC820. A temperature sensor is not integrated. For automatic temperature compensation, a separate temperature sensor (e.g. Apera Instruments MP500) is required, or the temperature must be entered manually.\u003c\/p\u003e \u003cstrong\u003eTechnical Specifications:\u003c\/strong\u003e \u003ctable class=\"\" table_custom table-bordered table-condensed\u003e \u003ctbody\u003e \u003ctr\u003e \u003ctd\u003eMeasuring range\u003c\/td\u003e \u003ctd\u003e(0 ~ 14) pH\u003c\/td\u003e \u003ctd\u003eElectrolyte\u003c\/td\u003e \u003ctd\u003ePolymer\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eRecommended operating temperature\u003c\/td\u003e \u003ctd\u003e(-5 ~ 80) °C\u003c\/td\u003e \u003ctd\u003eStorage solution\u003c\/td\u003e \u003ctd\u003e3M KCl\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eShank material\u003c\/td\u003e \u003ctd\u003eLead free glass\u003c\/td\u003e \u003ctd\u003eMembrane resistance\u003c\/td\u003e \u003ctd\u003e\u0026lt;200 MΩ\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eGlass membrane type\u003c\/td\u003e \u003ctd\u003eS\u003c\/td\u003e \u003ctd\u003eElectrode dimension\u003c\/td\u003e \u003ctd\u003e(Ø12×120) mm\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eReference system\u003c\/td\u003e \u003ctd\u003eLong Life\u003c\/td\u003e \u003ctd\u003eConnection\u003c\/td\u003e \u003ctd\u003eBNC\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eDiaphragm\u003c\/td\u003e \u003ctd\u003e2-porous\u003c\/td\u003e \u003ctd\u003eCable\u003c\/td\u003e \u003ctd\u003eØ3mm×1m\u003c\/td\u003e \u003c\/tr\u003e \u003c\/tbody\u003e \u003c\/table\u003e \u003cbr\u003e This electrode has a 6-month manufacturer's warranty.","brand":"IDL","offers":[{"title":"1 piece","offer_id":56356621812044,"sku":"28APE190257","price":109.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0955\/4827\/7068\/files\/779-LabSen231.png?v=1767082462","url":"https:\/\/www.luminixhealth.com\/de-de\/products\/labsenreg231-combination-ph-electrode-for-wastewater-suspension-and","provider":"Luminix Health","version":"1.0","type":"link"}
