Visual colorimeter designed to optimize the use of Lovibond™ glass filters in order to express color in terms of Lovibond Red, Yellow, Blue and Neutral. It is arranged with two adjacent fields of view, seen through the viewing tube, so that the product in the sample field and a white reflective surface in the comparison field are observed side by side, suitably illuminated. The Lovibond glasses are introduced into the comparison field by a simple system of sliding racks, allowing the user to compare the color of light which is either transmitted through or reflected from the sample with that transmitted through the glasses. A series of neutral glasses in racks is also supplied; these can be introduced into the sample field to dull the color of products which are too bright to obtain a good color match using Lovibond Red, Yellow or Blue glasses. The racks are varied until a visual color match is found for the light from the sample and its color can then be expressed in Lovibond units.For applications including fats and fatty oils, bleached lac, liquid chemicals and pharmaceuticalsGlass color standards housed in durable racksExternal, low-voltage regulated power supplyPrismatic optical system provides improved color matchingBalanced field of viewDiffused tungsten-halogen light sourceReplaceable sample chamber linerDesigned to allow easy cleaning and maintenanceSpecificationsMeasuring principle: visual, in terms of Lovibond unitsModes: transmittance, reflectanceRange: 0.1-79.9 Red, Yellow; 0.1-49.9 Blue; 0.1-3.9 NeutralResolution: 0.1 Lovibond unitOptical system: 11 glass-filled nylon racks containing a graduated range of Lovibond color glassesViewing system: fully adjustable, prismatic with integral blue filter for light standardizationLight source: 2 x 12V, 10w tungsten halogen lampIlluminant: approximates to daylightPath length: up to 153mm (6 in.)Power pack: 12V AC, switchable to suit 220/110V supplyCertificationsCE approved
