how to test a uv light with a multimeter

An instrument that measures the intensity of ultraviolet radiation is called an UV light intensity meter, also known as an UV light meter. B+W 486. Since we cannot avoid sunlight while outdoors, we can physically or chemically block the sun. High display resolution. Here is photo below shows the test system: The following is the test report of this product for your reference: Lisun Instruments Limited was found by LISUN GROUP in 2003. Though, we know from this post that white LED have some infrared light component other than visible. If the needle doesnt move much, turn the multimeters voltage setting down a little bit. If you have any questions about our UV lamp intensity meter, please feel free to contact us by email. Last Updated: September 15, 2022 Then, you will need to hold the positive lead of the multimeter to the positive terminal of the UV light and the negative lead of the multimeter to the negative terminal of the UV light.
