K13500 Automated Colorimeter
Provides photometric color measurements required for purity and quality control testing that are objective, accurate, and consistent over a wide variety of samples. The new LockIN- technology now allows a spectrophotometric measurement with an open cuvette compartement and independent from foreign light influences. Microprocessor-based unit features a modern optical system with reference beam path (RST-technology) and measures samples in comparison to 15 possible color ranges. The colorimeter is custom configured to user specifications, and easily perform single measurement, multi-measurement, color difference, and color strength tests. The optional barcode reader provides for easy sample and user identification. Tests take less than one minute to complete, and results can be either displayed on LCD screen or sent to an external printer.
