LS122 IR Power Meter

LS122 IR Power Meter


I.IR Power Meter Introduction

      Linshang LS122 infrared power meter is the same model of Weigu energy tester, also called infrared energy receiver. This is an instrument with a wide receiving range. It is mainly used to measure the infrared blocking rate of materials. It is suitable for the display of thermal insulation effects of thermal insulation glass, solar film and other materials. It can also be used to measure the radiant energy power density of various light sources, that is, the radiant energy power per square meter, the unit is W / m².
