. There are three different things you need to know: first, whether it's emitting UV light at all, second, whether that light is of a high enough energy to be useful in destroying germs, and third, how powerful the light isor put another way, how close you need to hold it for how long to effectively destroy pathogens. I have just arrived home again from Thailand with two new bulbs I bought for my drinking water filter in but they are 240V and I found out I needed 60V bulbs. I again tested the connections and in the pond filter lamp and saw 240V but when I inserted the lamp and turned on the power the main house circuit breaker tripped. wikiHow, Inc. is the copyright holder of this image under U.S. and international copyright laws.

If the voltage in the display is below 400 mV, then it is possible that the cathode and anode are touching, or the probes are touching. Solar energy (sunlight) contains light we can see, and some we cannot. The ultraviolet lamps irradiation intensity gradually decreases during use, so the intensity of disinfecting ultraviolet rays should be measured frequently, once it drops below the required intensity; it should be replaced in time, so it is required to use an ultraviolet radiation meter to detect the intensity of ultraviolet radiation. The LibreTexts libraries arePowered by NICE CXone Expertand are supported by the Department of Education Open Textbook Pilot Project, the UC Davis Office of the Provost, the UC Davis Library, the California State University Affordable Learning Solutions Program, and Merlot.
