These probes produce a voltage that changes as a titrant is dosed into the sample being analysed. The HI-90060X family of photometric probes use the principle of absorbance at a specific wavelength to identify the equivalence point of a titration with the use of a colour indicator.\u003c\/p\u003e \u003cp\u003eThe colour change in the solution causes a sharp change in the mV response. It is common for a complexometric titration to end in a flat mV response.\u003c\/p\u003e \u003cp\u003eWhen using the Hanna potentiometric titrator, it is possible to program the meter to use the first derivative as the end point.\u003c\/p\u003e \u003cp\u003eThis program is ideal as when a colour indicator is used, the colour change occurs very distinctly.\u003c\/p\u003e \u003cp\u003eWith the photometric probe there is no fill solution to change in order to be compatible with a non-aqueous sample and there is no pH sensor to foul.\u003c\/p\u003e \u003ch3\u003e\u003c\/h3\u003e \u003ch3\u003eMore about the probe\u003c\/h3\u003e \u003cp\u003eEach probe has a LED at a specific wavelength that shines light through the sample and reflected back by a platinum mirror sealed in glass.\u003c\/p\u003e \u003cp\u003eThe reflective measurement has a fixed path length and allows for a high colour sensitivity in a compact design.\u003c\/p\u003e \u003cp\u003eAll of the series has the same design but vary in the wavelength of light used for the photometric analysis.\u003c\/p\u003e \u003cp\u003eThe probes’ open cell design allows the solution to pass through with the use of a stirrer.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003emV range\u003c\/td\u003e\n\u003ctd\u003e10 to 1100mV\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWavelength\/LED Colour\u003c\/td\u003e\n\u003ctd\u003eHI-900601 @ 525nm\/green LEDHI-900602 @625nm\/red LEDHI-900603 @590nm\/orange LEDHI-900604 @470nm\/Blue LED\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLight source\u003c\/td\u003e\n\u003ctd\u003eLED\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMeasuring Cycle\u003c\/td\u003e\n\u003ctd\u003eLED pulsed at 1 kHz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLight detector\u003c\/td\u003e\n\u003ctd\u003esilicon photocell\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSample temperature\u003c\/td\u003e\n\u003ctd\u003e0 to 75°C\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\u003eBody length\/overall length\u003c\/td\u003e\n\u003ctd\u003e120mm\/200mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOuter Diameter\u003c\/td\u003e\n\u003ctd\u003e12mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConnection\u003c\/td\u003e\n\u003ctd\u003eBNC with 1.5 meter cable for connecting to titrator or autosampler\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower supply\u003c\/td\u003e\n\u003ctd\u003eps\/2 connector for connecting to titration system\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEnvironment\u003c\/td\u003e\n\u003ctd\u003e0 to 50°C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOrdering information\u003c\/td\u003e\n\u003ctd\u003eAll probes are supplied with an instruction manual and an electrode quality testing certificate.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\u003ch3\u003eDownloads\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e\u003ca href=\"https:\/\/www.hannainstruments.co.uk\/modules\/teapotknowledgehub\/uploads\/ist90060x_05_19-62e9107b02500.pdf\" target=\"_blank\"\u003eHI-90060X series Photometric Electrodes (PDF)\u003c\/a\u003e\u003c\/li\u003e\u003c\/ul\u003e","brand":"Hanna Instruments","offers":[{"title":"Default Title","offer_id":57640093647221,"sku":"HI-900604","price":494.95,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0574\/5511\/6439\/files\/hi-900604-photometric-electrode-with-blue-led-470-nm_065dd1c2-77e1-4523-ab76-615b6e461e19.jpg?v=1791581137","url":"https:\/\/testallwater.co.uk\/products\/hanna-instruments-hi-900604-photometric-electrode-with-blue-led-470-nm","provider":"Test All Water","version":"1.0","type":"link"}
