Koehler Instrument K13270 Color Spectrophotometer

Product Description
The K13270 utilizes reference beam technology to measure the four most important color scales used for liquid chemicals, resins, oils, fuels, and fats for liquid color measurement. The unit provides high precision photometric color measurements that are objective, accurate and consistent over a wide variety of samples required for quality control programs. The 7 inch TFT WVGA Color Graphic Touch Screen measures wavelengths from 380nm to 720nm and has the ability to store up to 400 color readings.
