The disc-shaped instrument records irradiance and accumulated energy for UVA, UVB, UVC and UVV, together with temperature and exposure duration. It suits process checks on UV curing, coating, exposure and printing equipment where the band-by-band result matters.\u003c\/p\u003e\u003cfigure\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0273\/2133\/5851\/files\/four-band-uv-energy-meter-ls138-energy-temperature-readings.jpg?v=1793769308\" alt=\"LS138 display showing separate band energy, irradiance and temperature\" width=\"990\" height=\"779\" loading=\"lazy\" style=\"max-width:100%;height:auto;\"\u003e\u003cfigcaption\u003eLS138 display showing separate band energy, irradiance and temperature\u003c\/figcaption\u003e\u003c\/figure\u003e\u003ch3\u003eFour spectral bands in one run\u003c\/h3\u003e\u003cp\u003eSelect one to four measurement bands before starting.
