OHSP-350series 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.

1、Advantages

▲Long telephoto optical system, the optical resolution of 2nm, a wider wavelength range, mainly measure the light source;

▲automatic zeroing technology and Electronic shutter Technology, Integral time 50μs～10000ms ,both stronger  and weaker light signal can be measured；

▲Fast switchgear，one key test;

▲5 "IPS high definition LCD touch screen；

▲Large battery capacity, Test usage time more than  24 hours time;
