COLORIMETER

LS172 is a handheld multifunctional colorimeter designed with a 45/0 annular illumination geometry. It uses a 3.5-inch IPS capacitive touch screen to provide an excellent operating experience. The color analyzer integrates multiple color charts, and it can quickly match the three closest color codes. The colorimeter also has a color comparison function, and supports a variety of standard color addition methods. The color difference threshold can be set, and the color difference formula can be flexibly selected, which can realize rapid QC testing.

UV ENERGY METER

LS128 is a professional UV energy meter for testing UV LED light sources, also known as a UV energy tester. With a spectral response range of 340nm to 420nm, it can test various UV LED lamps at different wavelengths, including 365nm, 375nm, 385nm, 395nm, and 405nm. It is the preferred choice for measuring the energy and power of UV LED light sources.

OPTICAL DENSITY METER

LS117 densitometer is an instrument that can measure both optical density and light transmittance. The instrument adopt the diffuse transmission principle which is suitable for the optical density test of opalescent translucent materials and frosted matte materials. The light source of the instrument complies with the CIE photopic luminosity function and can pass the inspection of Chinese national metrological institute.
