Precision Engineering Designed specifically for the Lovibond® Spectrophotometers, the instruments fit tightly into the housing to avoid any ambient lighting entering the sample. Accurate Measurements Every Time Each TRA kit is supplied with a white background plate to ensure consistency of readings. Background colour is critical when measuring translucent of transparent samples. Flexibility of Application Supplied with 3 different optical glass cells (10mm, 20 and 30 mm path length, the TRAs support a wide variety of samples. Thicker and more viscous materials are easier to handle if the largest 30 mm cell is used. In other cases, a smaller volume of sample may only be available, hence the 10 mm cell.
