LS131 UV Energy Meter

LS131 UV Energy Meter


I. LS131 UV Energy Meter Introduction

LS131 UV energy meter is a professional instrument for UV LED light source detection. The UV energy meter can detect the power and energy value of UV light source. The UV radiometer puck has wide spectral response and can test UV LED light sources in various bands such as 365nm, 375nm, 385nm, 395nm, 405nm. It is widely used in UV exposure, UV curing, UV flat printing, optical communications and other industries.
