About This Product

■Summary

- Portable measuring instrument equipped with a full-color touch panel screen, rechargeable battery, and SD card. -Weight is reduced to 1.7kg, making it convenient for outdoor measurements and carrying. ・For purposes other than brightness measurement, illuminance and irradiance can be measured by using optional optical accessories. ・In addition to USB, RS-232 can be installed as an interface, and it can be controlled by software and commands.

■Features

- Equipped with a rechargeable battery, allowing measurement outdoors. ・By combining accessories such as luminous intensity receptors and illuminance receptors, it is possible to measure various unit systems. ・Absolute value measurement that supports a wide dynamic range from low to high brightness ・Supports various measurement spot sizes by switching measurement angle (aperture) ・With built-in rechargeable battery, the measuring device itself can be used independently. ・AutoSync function that synchronizes to the measurement target frequency (20 to 400Hz) ・With a wide range of optical accessories, measurement of units other than luminance is possible. ・Dedicated software and command control

■Measurable units

Brightness, radiance, chromaticity, color temperature, illuminance, irradiance, luminous intensity, radiant intensity, total luminous flux, radiant flux, transmittance, reflectance

■Accessories

・Radiance and brightness accessories: objective lenses, fiber probes ・Intensity and luminosity accessories: LED receptors ・Irradiance and illuminance accessories: Cosine receptor ・Other accessories: ND filter, standard diffuser plate

■Application
