Analysis Labs




CLM-196 is a benchtop tristimulus colorimeter in a compact stainless steel case.

Designed for colorimetric detection 60 times more accurate than human eye, CLM-196 colorimeter it’s flawless for measurements for powders and liquids.

Thanks to a (45°c:0°) measurement geometry and very uniform illumination provided by integrated LEDs, is ensured long-term stability and minimizing user calibration.

Benchtop colorimeter is powered and interfaced by USB port to a PC or a laptop. The included application software is compatible with Microsoft Windows operating system.

Performed the sample measurement, application software allows you to analyze and process data (please refer to Software section).
