The measurement data of CL-70F colorimeter is displayed in the form of CRI color rendering index, tristimulus value, illuminance, chromaticity, characteristic wavelength, color purity, correlated color temperature, and difference from the target.

Product Details

A cost-effective solution for measuring color and illuminance of light sources

Color rendering illuminance meter CL-70FIt is a lightweight handheld measuring instrument used to measure the color and illuminance of light sources, including new LED and EL light sources. The measurement data is displayed in the form of CRI color rendering index, tristimulus value, illuminance, chromaticity, characteristic wavelength, color purity, correlated color temperature, and difference from the target.

The CL-70F can be paired with a separately purchased flash sync line for spectral measurement of photographic flashes.

The practical software CL-SU1w, which comes as a standard accessory, includes more advanced features for data capture and analysis.
