Key Features:

  • Designed for Industrial Use
  • 4.3" Color Touchscreen
  • 270º Swivel Head
  • Powered by AA Batteries
  • CMOS Linear Image Sensor

Utility Software

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.

Flash Measurement

The world’s first* stand-alone spectrometer that measure the flash 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) offers easy settings and updating firmware 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.

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.

User-Friendly Design
