The Sekonic C-7000 Spectrometer Color Meterfrom Sekonic C-7000 Spectrometer Color Meteris 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 overwhelming popularity of 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 processes along with varying color and illumination qualities can often result in consistency issues. To address these lighting challenges, Sekonic has created the C-7000 to offer advanced precision lighting control for the Photo, Video, and Cine industries.

Information screens such as Correlated Color Temperature, Illuminance, Color Rendering Index (CRI), Tristimulus Value, Chromaticity Coordinates (for

CIE1931/CIE1964 & CIE1976 standards), Peak Wavelength, Excitation Purity and Photosynthetic Photon Flux Density, and more are displayed on the 4.3" color touch screen display. The enhanced measurement data and display modes of the C-7000 provide the information that is widely utilized in light fixture manufacturing and quality control, as well as monitoring illumination of offices, roadways, and public facilities to meet government lighting standards. Indoor agricultural lighting, precision medical light control and many more lighting industries will find the C-7000 of particular usefulness in their daily application to meet requirements for lighting control.

The C-7000 is also computer-friendly. Connect the C-7000 to a Windows-based PC and users will be able to make meter settings with the C-7000 Utility (included with the meter) and output CSV format files of measurement data in 1 nanometer (nm)

wavelength increments from 380 to 780nm. Additionally, graphs of spectral distribution, CRI, and chromaticity diagrams for CIE 1931(1964) and CIE1976 color spaces can be outputted as well.

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.

Q: 1. Can the C-7000 automatically take multiple data points (30 points every 1 minute)?

A: The Sekonic C-7000 Spectrometer Color Meter Bundle Kit BH #SEC7000K does not have the ability to do 30 readings per minute.

Q: 2. Can this be used for color analysis of roasted coffee beans ?

A: No, the following unit is a spectro but will only capture measurements of all forms of continuous light. Please review the following item if you are trying to capture the color code of a coffee bean. Datacolor ColorReader Color Matching Tool https://bhpho.to/3BLhrdS

Q: 3. Is there an "R" version like the C-700R that can trigger flash via radio slave or does it ONLY have a PC cord terminal?

A: The Sekonic SPECTROMETER C-800 can only be connected to a flash using the PC synch terminal. This unit is not designed to work with wireless modules to trigger flashes.

Q: 4. Can this unit measure PAR of grow lights. I see it measures PPFD. Is this PPFD the same as PAR? I'm new at grow lights. It looks to be the same. Ie mol m2 s-1 or. umol m2 s-1

Q: 9. In what increments will it display measured lux? Eg: 0-1999lx rounded to 1s place. 2000-19,990 to the 10s place etc. (Not range)

A: The Sekonic SPECTROMETER C-800 displays lux to the single digits. For example 2161 is a lux reading that it may show.

Q: 10. Can this also be used to measure light levels (F stops)? Ambient, spot, or incident?

A: This meter can be used to measure incident light, measured as lux. There are no aperture or shutter speed or ISO numbers on this meter. These would need to be derived from the lux measurement and the ISO speed rating, to determine f/stops and shutter speeds. As a reference point for your calculations, Exposure Value (EV) 0 is equivalent to 1 second at f/1.0. At ISO 32 film speed, EV0 is the correct exposure for 10 lux incident light level. For ISO 500, at 110,000 lux, the correct exposure would be EV17. Remember that EV represents a collection of equivalent settings, so EV17 could be 1/1000 sec at f/11 or 1/500 sec at f/16 or 1/250 at f/22 or 1/125 at f/32 or 1/60 at f/44, and so on. For the same ISO 500 speed, 55,000 lux would require one unit lower EV than at 110,000 lux, thus 55,000 lux would require EV16 for ISO 500. With 110,000 lux and ISO 125, the correct exposure would be EV15. One of the possible shutter & aperture combinations for EV15 would be 1/250 at f/11. These examples should enable you to create exposure tables for yourself, relative to the lux readings you get from this meter. It does beautifully at measuring the spectrum of light sources and determining color rendering index and color temperature.
