Description
Luminance/ Brightness Meter
OHSP-350 series handheld spectral colorimeter illuminance meter set of measurement function Spectrum, illumination, chromaticity, light flicker in one. Using 5 inch screen, the measurement parameters and curves are displayed in real time. It is convenient to use and can be directly tested in the lighting field.,Not only measurable LED wide spectrum light source, but also can measure the narrow spectrum light sources, such as CFL, HID, and so on.,It can also be used to test the environmental light of stage design, building light, plant growth lamp, engineering application and so on.
OHSP-350C: Spectral irradiance colorimeter, integrated spectrum, CCT, CRI, Lux, irradiation. etc parameters in one. With 5 inch touch screen, Real-time display of measurement parameters and curves, use convenient and fast, not only measure LED wide spectrum light source, but also measure CFL, HID narrow spectrum light source.
OHSP-350P: Plant lighting analyzer , add plant grow light parameters PAR, PPFD, YPFD and so on.especially designed for accurat measurement and analysis of Plant Lighting . It is widely used in light analysis, research and communication in plant growth light.
OHSP-660T: Spectral Transmittance Tester, integrated Spectrum, Transmittance, L*A*B in one, can test material and lens immediately.
