Product Overview

The SPECTROMASTER C-7000 is a portable handheld spectrometer, designed especially for industrial use.

Utilizing Sekonic’s CMOS linear image sensor design and large touch-screen color display, the C-7000 can measure and accurately describe LED, HMI, fluorescent, as well as natural light and electronic flash.

The C-7000’s Utility software, displays memorized data in several ways and outputs spectral data in 1nm (nanometer) increments in CSV format.

The C-7000 is an important measuring tool for quality control in lamp manufacturing, medical facilities, educational / office safety and health standards, agricultural lighting / design and many more industrial uses.
