PROCESSING & EQUIPMENT Iodine colour scale in automatic calorimeter A new colour measurement scale, the Iodine scale, has been introduced to further extend the range of colouc measurement capabilities offered by the fully automatic calorimeter, the PFX-990 from Tintometer Ltd. As with the existing colour scales, a single measurement allows calculation of the Iodine scale value. The Iodine colour scale is a one-dimensional scale used extensively throughout Europe for the colour grading of resins, plasticizers and solvents whose colour is similar to an iodine/potassium iodide solution. The colour scale is expressed from 0 to 500 units. For very light colours with measurement values of 1 or less on the Iodine scale, the Hazen (APHA) scale can be used, which is also a standard facility on the PFX-990. The new scale is available as an EPROM retrofit kit for existing PFX-990 users, and a new version of software is also available for PC-control of the instrument when fitted with the Iodine scale.
