Protable Spectrum-Illuminance Meter
1. Introduction
OHSP-350 portable Spectrum-illuminance meter is an equipment integrated the test functions of spectrum, colorimetry, illuminance, radiate and etc. Adopts 5 inch LCD screen to display all kinds of parameters and curve at real time, built-in CCD senor and advanced information processing chip to ensure the stability of the optical signal. It is easy to operate and can realize site test. This equipment can not only test LED, CFL and HID luminaires, and also can apply to the conditions of stage design, architectural lighting, grow lights and engineering application.
Test parameters: correlated color temperature (CCT), chromaticity coordinates (x, y, u, v), peak wavelength, central wavelength, dominant wavelength, centroid wavelength, half width, illuminance, candle light, color rendering index (CRI), SDCM, purity, red ratio, green ratio, blue radio, CIE1931 chromaticity diagram, CIE1960 chromaticity diagram, CIE1976 chromaticity diagram, SDCM diagram, CRI circular diagram
