This sensing electrode is made with high temperature glass and is to be used in conjunction with a reference half-cell electrode. \u003c\/p\u003e\u003cp\u003eThis design is ideal for use in strong alkaline solutions as well as for general purpose measurements.\u003c\/p\u003e \u003cul\u003e \u003cli\u003eHigh Temperature (HT) Glass\u003c\/li\u003e \u003cli\u003eHalf-Cell Design\u003c\/li\u003e \u003cli\u003eBNC Connection\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003eThe HI-2111B uses high temperature (HT) glass, spherical bulb, and glass body.

A pH electrode with general purpose (GP) glass will have a resistance of 100 megaohms at 25°C while the resistance of HT glass is around 400 megaohms at 25°C. As the HI-2111B is used at elevated temperatures, the resistance decreases to approach that of GP glass. The HI-2111B is suitable to use with samples that measure from 0 to 100°C.\u003c\/p\u003e \u003ch3\u003eSpherical Bulb\u003c\/h3\u003e \u003cp\u003eThe spherical bulb is for general purpose use. Other tip shapes include conic for penetration and flat tip for surface measurements.\u003c\/p\u003e \u003ch3\u003eGlass Body\u003c\/h3\u003e \u003cp\u003eThe glass body is ideal for laboratory use. The glass is resistant to many harsh chemicals and is easily cleaned. The glass body also allows for a fast transfer of heat to the internal reference electrolyte. The mV generated by the reference cell is temperature dependent. The faster the electrode reaches equilibrium, the steadier the reference potential.\u003c\/p\u003e \u003ch3\u003eBNC Connector\u003c\/h3\u003e \u003cp\u003eThe HI-2111B uses a BNC connector. This type of connector is universal in that it can be used on any pH meter that has the female BNC probe input. \u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eDescription\u003c\/td\u003e\n\u003ctd\u003epH Half-cell\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRange\u003c\/td\u003e\n\u003ctd\u003epH: 0 to 14\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRecommended operating temp\u003c\/td\u003e\n\u003ctd\u003e0 to 100°C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTip\/Shape\u003c\/td\u003e\n\u003ctd\u003espheric (dia: 9.5mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBody material\u003c\/td\u003e\n\u003ctd\u003eglass\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCable\u003c\/td\u003e\n\u003ctd\u003ecoaxial\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRecommended use\u003c\/td\u003e\n\u003ctd\u003egeneral purpose, strong alkaline solutions\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003econnection\u003c\/td\u003e\n\u003ctd\u003eBNC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e","brand":"Hanna Instruments","offers":[{"title":"Default Title","offer_id":57640057831797,"sku":"HI-2111B","price":181.74,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0574\/5511\/6439\/files\/glass-body-ph-half-cell-electrode.jpg?v=1791579964","url":"https:\/\/testallwater.co.uk\/products\/hanna-instruments-hi-2111b-glass-bodied-ph-half-cell-electrode","provider":"Test All Water","version":"1.0","type":"link"}
