LS330 illuminance meter is a versatile instrument designed with a sensor. The illuminance meter is used for measuring Lux, UV index, flicker frequency, standard deviation of color matching (SDCM), color rendering index (), correlated color temperature (CCT), blue light hazard ratio, temperature, and humidity in various scenarios such as lamps and lanterns lighting, outdoor lighting, greenhouse lighting, and stage lighting. meter digital also can display the curve, which helps identify the type of lighting fixture.<br><br>1.
