C-7000 Chroma Meter For CRI Color Temperature Lux Illumination

Color Temperature SPECTROMASTER C-7000 Chroma Meter or Illumination Meter

Lighting solutions and applications have never been in greater demand and expansion as they are today. With the overwhelming popularity of these new light sources such as advanced LED and Organic Electroluminescence, the need to understand, manage and control these sophisticated illumination systems is essential. Manufacturing quality and process along with varying color and illumination qualities can often result in consistency issues. To address these lighting challenges, Sekonic Corporation, a leader for over six decades providing advanced precision lighting control for the Photo / Video / Cine industry has offered an ergonomic, intuitive Spectrometer, the SPECTROMASTER C-7000.

The new SPECTROMASTER C-7000 is a portable handheld spectrometer, designed especially for industrial use. Utilizing Sekonic’s CMOS linear image sensor design and software, the
C-7000 can measure every light source (LED, HMI, fluorescent, natural light and electronic flash spectrum) with remarkable precision and data feedback.

With the C-7000 Utility software, output of memorized data is provided at every 1nm (nanometer) increments in CSV format. The C-7000 can be utilized to measure data for light manufactures quality control, medical facilities, educational / office safety and health standards, agricultural lighting / design and many more industrial uses.

Measures LED, HMI, Fluorescent, Tungsten, Natural Light and Flash in 1 nanome- ter (nm) output wavelength increments from 380 to 780 nm. It conforms to re- quirement of “Illuminance meter class” for JIS C 1609-1: 2006 “Illuminance meters Part 1: General measuring instruments” Class A, and DIN 5032 Part 7 Class C.

Wide Measurement Range of Color Temperature and Illuminance

Wide measurement range of Color Temperature (1,563 to 100,000K) and illumination (1 to 200,000lx = 0.1 to 18,600fc in ambient light, 20 to 20,500lx • s = 1.86 to 1,900fc • s in flash light)

User-Friendly Design

270º swivel head, dark calibration without cap, large 4.3” color touch panel LCD and Customize function, convenient AA batteries for power source.
