The Sekonic C-7000 SpectroMaster is a portable digital exposure meter, specially designed for industrial use. It is an advanced light meter capable of reading all light sources, whether it’s an LED flash, bulb, HMI, fluorescent light or natural light spectrum. Here you can enjoy a professional lecture from nine different display modes, from the large 4.3 inch color display. The Sekonic C-7000 SpectroMaster has a very impressive accuracy and response specs and a wide range of values in all modes. The Sekonic CMOS image sensor with linear design and the large color touch screen make possible that the C-7000 accurately describes measurements.

The C-7000 Utility software (only Windows version available) shows stored data in different ways in which spectral data are observed in 1nm steps (nanometer) in CSV format. The C-7000 is an important measuring instrument for quality control in lamp production, medical facilities, education / office health and safety standards, agricultural lighting / design and many more industrial applications.
