This sensing portion of this electrode is made with general purpose glass. The HI-1297D also has an extendable cloth type junction along with a built-in temperature sensor and amplifier within a single probe design.\u003c\/p\u003e\u003cp\u003eThis design consideration is ideal for measuring the pH in municipal and industrial wastewater, swimming pools, and various field applications. \u003c\/p\u003e \u003cul\u003e \u003cli\u003eTitanium Body\u003c\/li\u003e \u003cli\u003eBuilt-In Temperature Sensor\u003c\/li\u003e \u003cli\u003eExtendable Cloth Junction\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003eThe HI-1297D is a pH\/ORP electrode for wastewater, municipal water, water treatment and swimming pools.\u003c\/p\u003e \u003cp\u003eThe HI-1297D uses general purpose (GP) glass, spherical bulb, titanium body, and cloth junction with gel electrolyte.\u003c\/p\u003e \u003ch3\u003eGeneral Purpose Glass Formulation\u003c\/h3\u003e \u003cp\u003eGeneral Purpose (GP) glass, as the name implies, is a standard glass formulation that is used for general use. A pH electrode with GP glass will have a resistance of 100 megaohms at 25°C and is suited for measuring pH of samples that are at ambient temperatures. The HI-1297D is suitable to use with samples that measure from 0 to 80°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\u003eTitanium Body\u003c\/h3\u003e \u003cp\u003eA titanium body increases immunity to electrostatic and magnetic fields. It also allows for strong corrosion resistance, even in seawater. Our titanium bodied electrodes’ outer casings also serve as a matching pin. A matching pin is a differential measurement technique used to eliminate ground loops and common mode perturbations for the measurement system. In a system without a matching pin, electrical currents in the samples can affect the reference half cell voltage. The matching pin isolates these current\/magnetic fields from the reference electrode for safe, precise pH measurements.\u003c\/p\u003e \u003ch3\u003eCloth Junction\u003c\/h3\u003e \u003cp\u003eThis type of junction is often used on electrodes with gelled electrolytes. The advantage of this junction is it is renewable; as the cloth-like material is pulled out from its position, the junction is renewed with an uncontaminated, fresh surface.\u003c\/p\u003e \u003ch3\u003eDIN Connector\u003c\/h3\u003e \u003cp\u003eThe HI-1297D uses a DIN connector. This type of connector is generally proprietary to the meters they are supplied with and may not be interchangeable. Other types of connectors include BNC, screw type, T-type, and 3.5mm to name a few.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eReference\u003c\/td\u003e\n\u003ctd\u003esingle, Ag\/AgCl\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eJunction\/Flow Rate\u003c\/td\u003e\n\u003ctd\u003ecloth\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eElectrolyte\u003c\/td\u003e\n\u003ctd\u003egel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMax Pressure\u003c\/td\u003e\n\u003ctd\u003e3 bar\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRange\u003c\/td\u003e\n\u003ctd\u003epH: 0 to 13; ORP\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRecommendedOperating Temp.\u003c\/td\u003e\n\u003ctd\u003e0 to 80°C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTip\/Shape\u003c\/td\u003e\n\u003ctd\u003epH: conic (3 mm); ORP: platinum sensor\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTemperature Sensor\u003c\/td\u003e\n\u003ctd\u003eyes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAmplifier\u003c\/td\u003e\n\u003ctd\u003eyes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBody Material\u003c\/td\u003e\n\u003ctd\u003etitanium\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCable\u003c\/td\u003e\n\u003ctd\u003e7-pole; 1 m (3.3')\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConnection\u003c\/td\u003e\n\u003ctd\u003eDIN\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e","brand":"Hanna Instruments","offers":[{"title":"Default Title","offer_id":57640055898485,"sku":"HI-1297D","price":374.2,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0574\/5511\/6439\/files\/ph-orp-temperature-probe-for-hi-991002-hi-991003.jpg?v=1791579887","url":"https:\/\/testallwater.co.uk\/products\/hanna-instruments-hi-1297d-ph-orp-temperature-probe","provider":"Test All Water","version":"1.0","type":"link"}
