CM-5 Spectrophotometer

Standalone Multi-Function Top Port Spectrophotometer For Color Measurement In Reflectance And Transmittance 

Konica Minolta CM-5 spectrophotometer makes color measurement simple. As easy as 1-2-3. Power “ON” the CM-5, wait for the calibration to be completed and start taking measurement. That’s simple. No PC is required, the CM-5 has a wide range of advanced functions including specialized indices for a  wide variety of application and thanks to the large color LCD screen that makes results easy to read.

The CM-5 spectrophotometer is a very versatile top port benchtop instrument for measuring the color of solid, powder, paste. granular or liquid sample in either reflecatance of transmittance. This instrument thus us a perfect all rounder lab equipment for application such as food, flavors fragrance, chemical and pharmaceuticals application.

CM-5 spectrophotmeter is an easy to use color measurement instrument and thanks to the large color LCD screen, keyboard and the extensive firmware offering most major colormetric systems including industry specific indices to measure transparent liquid such as Gardner, Hazen/APHA, Iodine, European and US Pharmacopeia.
