CSM 22 Introduction VIdeo <<


CSM 22 is a handheld spectrophotometer colorimeter used for high-quality color measurement. Featuring a dual aperture 10/8 mm and 5/4 mm, and including SCI and SCE specular modes for industrial color measuring applications, the CSM 22 offers a long battery life, a long 18-color lamp with UV light, and an easy-to-use portable design. The CSM 22 covers the full spectrum from 400 to 700 nm in 10 nm increments. The powerful battery allows up to 5000 daily measurements. The software supports both SCI and SCE spectral measurements at once. The unit features a 3.5 inch TFT color touch screen and a 256 image element CMOS image array for superior usability and accuracy.


The high-quality processing of the spectrometer is very fast. The ability to choose aperture size and light source allows the user to discriminate between colors that may look the same. Six color space choices allow the user to choose the best space for their samples. The 256 image element double array CMOS imager allows measurement from 400 to 700 nm in 10 nm increments. The measured data can be transmitted to a computer via Bluetooth or USB. Sophisticated analysis software is also included in the delivery contents that includes the USB cable.
