The Lovibond Tintometer is a visual colorimeter designed to optimise the use of Lovibond glass filters.
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 illumin ated. The Lovibond glasses are introduced into the comparison field by a simple system of sliding racks, allowing the user to compare the colour 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 colour of products which are too bright to obtain a good colour match using Lovibond Red, Yellow or Blue glasses. The racks are varied until a visual colour match is found for the light from the sample and its colour can then be expressed in Lovibond units.
The new Lovibond® Handbook of Methods comprise the currently existing 155 Lovibond® methods and explains them currently in nine languages.
Lovibond's new Handbook describes each method in detail, with step-by-step pictorial instructions. With an introductory chapter with basics about water analysis, references for sources and norms, suitable reagents including part numbers, explanations of potential interferences and much more, the Lovibond® Handbook of Methods will become your new “go-to” reference resource for water testing.
The additional advantage, each method contains a barcode which starts the test recognition automatically. The first instrument which maintains this user-friendly operating concept are the Spectrophotometers XD 7000 and XD 7500.
