Product Overview

• Highly reliable and accurate – one of the most reliable and accurate spectrophotometers available by utilizing state-of-the-art technology

• Windows compatible – Compatibility allows it to be controlled from a computer with Windows software

• Measurement area switching – flexibility allow users to select either 25.4mm, 8mm, or 3x5mm measurement areas

• Can measure reflective, transparent, and fluorescent color – using SCI/SCE switching, diffused lighting, and/or UV cut filters, users can easily measure reflective, transparent, and reflective colors

• International standards – many standards are included in the CM-3700ACIE, such as ISO, ASTM, DIN, and JIS

• Xenon flash – allows even very dark shades to be accurately measured with this instrument

• USB Connectivity – faster communication and an easier connection to PCs with the USB interface

• Dampening sample holder – not only does the featured long arm enable measuring the center of an A4-sized sample, a damper also provides a “slow-close” effect, preventing the sample holder from slamming shut, which could possibly damage the measurement sample

• Protective frame power switch – to decrease the likelihood of accidentally powering off during operation, a protective frame has been added around the power switch
