Sekonic C-7000 User Manual
THE INTUITIVE SPECTROMETER WITH
COLOR TOUCH SCREEN THAT MEASURES
EVERY LIGHT PLUS ELECTRONIC FLASH
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.
SpectroMaSter
C-7000
Precise Measurement
Measures LED, HMI, Fluorescent, Tungsten, Natural Light and Flash in 1 nanometer (nm) output wavelength increments from 380 to 780 nm. It conforms to requirement 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.
Flash Measurement
The world’s rst* stand-alone spectrometer that measure the ash light with synchro cord
connection or cordless mode with its sophisticated and unique accumulation type sensor.

Memory Function and Data Management
Up to 999 measurements can be stored in memory. C-7000
Utility (in CD-ROM included in the package) oers easy
settings and updating rmware of the meter. Via C-7000
Utility software, the output of the
spectrum data at every 1nm in
CSV format and the graphics of
the spectrum distribution graph,
CIE1931(1964), CIE1976 diagram,
CRI graph bar in JPEG/BMP/PNG
format are also available.
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 ash 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.
Display Modes
Intuitive color touch screens oer easy navigation, quick
selection and easy to read measurements in 8 modes.
