Its external sensor responds over 230–280nm with a 254nm peak reference. The supplied one-meter test hook helps position the sensor for lamp checks, while the handheld unit stores time-based measurements for later review.\u003c\/p\u003e\u003cfigure\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0273\/2133\/5851\/files\/uvc-light-meter-ls126c-recording-display.jpg?v=1793769237\" alt=\"LS126C display identifying irradiance, energy, duration and clock\" width=\"990\" height=\"750\" loading=\"lazy\" style=\"max-width:100%;height:auto;\"\u003e\u003cfigcaption\u003eLS126C display identifying irradiance, energy, duration and clock\u003c\/figcaption\u003e\u003c\/figure\u003e\u003ch3\u003eRecord changes over time\u003c\/h3\u003e\u003cp\u003eSelect a storage interval of 1, 10 or 60 seconds for a recording period of 10, 100 or 600 minutes when automatic shutdown is disabled.
