Linshang LS332 Screen Luminance Meter Spectrometer for Display Screen Lamps Brightness Flicker Frequency CCT CRI Testing

Descripción de Linshang LS332 Screen Luminance Meter Spectrometer for Display Screen Lamps Brightness Flicker Frequency CCT CRI Testing

The device is a versatile luminance meter featuring a built-in spectral sensor. It is capable of measuring luminance, flicker, correlated color temperature (CCT), and color rendering index (CRI) for displays, backlight modules, lighting fixtures, and other similar applications. In addition, it can present the spectral distribution curve, allowing users to identify the characteristics and types of backlight sources with ease.
