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.
