Colour classes are expressed in millimeters (mm) Pfund as compared to an analytical grade glycerol standard reference.\u003c\/p\u003e \u003cp\u003eThe natural colour of honey comes in many tones: from straw yellow to amber, from dark amber to almost black with a hint of red. The colour of untreated honey originates from the botanical varieties used by the bees; for this reason, its coloration allows one to commercially identify the original floral type.\u003c\/p\u003e \u003cp\u003eThe colour of honey tends to darken with age or change according to the method of conservation or production used by beekeepers. These practices can include the use of old beehives, contact with metals, the temperature of conservation, and exposure to light.\u003c\/p\u003e \u003cp\u003eThe HI-96785 uses direct measurement to determine honey coloration ranging from 0 to 150 mm Pfund. This photometer has a tungsten lamp with a narrow band interference filter to isolate the 420 nm and 525 nm wavelength. All samples are measured in a square cuvette having a 10 mm light path and are compared to a glycerol standard. The percent light transmittance readings are directly displayed as mm Pfund. With its advanced optical system, the highly precise meter eliminates subjectivity to provide readings that are accurate and repeatable.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eWater White\u003c\/td\u003e\n\u003ctd\u003e0mm – 8mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eExtra White\u003c\/td\u003e\n\u003ctd\u003e8mm – 17mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWhite\u003c\/td\u003e\n\u003ctd\u003e17mm – 34mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eExtra Light Amber\u003c\/td\u003e\n\u003ctd\u003e34mm – 50mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLight Amber\u003c\/td\u003e\n\u003ctd\u003e50mm – 85mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAmber\u003c\/td\u003e\n\u003ctd\u003e85mm – 114mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDark Amber\u003c\/td\u003e\n\u003ctd\u003e114mm – 140mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRange\u003c\/td\u003e\n\u003ctd\u003e0 to 150mm Pfund\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eResolution\u003c\/td\u003e\n\u003ctd\u003e1 mm Pfund\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAccuracy @25°C\u003c\/td\u003e\n\u003ctd\u003e±2 mm Pfund @ 80mm Pfund\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLight Source\u003c\/td\u003e\n\u003ctd\u003eTungsten lamp\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLight Detector\u003c\/td\u003e\n\u003ctd\u003eSilicon photocell with narrow band interference filter @ 420nm and 525nm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Supply\u003c\/td\u003e\n\u003ctd\u003e9V battery\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAuto-off\u003c\/td\u003e\n\u003ctd\u003eAfter ten minutes of non-use in measurement mode; after one hour of non-use in calibration mode; with last reading reminder\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEnvironment\u003c\/td\u003e\n\u003ctd\u003e0 to 50°\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e193 x 104 x 69mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e360g\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMethod\u003c\/td\u003e\n\u003ctd\u003eDirect measure\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOrdering Information\u003c\/td\u003e\n\u003ctd\u003eHI-96785 is supplied with sample cuvettes (2) with caps, 9V battery, instrument quality certificate and instruction manual.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAccessories (sold separately)\u003c\/td\u003e\n\u003ctd\u003eHI-93703-57 Glycerol, (4) 30ml; HI-93703-56 consists of 90 matched square cuvettes, 30ml of glycerol and (2) 5 ml syringes (75 tests average); HI-70662 Cleaning solution for honey meter (30ml)\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\/man_96785_14_01_2011-60bf5bc4e8ded.pdf\" target=\"_blank\"\u003eHI-96785 Honey Colour Grade Photometer (PDF)\u003c\/a\u003e\u003c\/li\u003e\u003c\/ul\u003e","brand":"Hanna Instruments","offers":[{"title":"Default Title","offer_id":57640101937525,"sku":"HI-96785","price":679.15,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0574\/5511\/6439\/files\/portable-honey-grade-analyzer.jpg?v=1791581337","url":"https:\/\/testallwater.co.uk\/products\/hanna-instruments-hi-96785-honey-colour-grade-portable-photometer","provider":"Test All Water","version":"1.0","type":"link"}
