\nIn a joint project, sglux and PTB investigated and developed methods and equipment to measure the spectral and weighted irradiance of high-efficiency UV-C emitters used in water disinfection plants. A calibration facility was set up to calibrate the microbicidal irradiance responsivity of actinic radiometers with respect to the weighted spectral irradiance of specially selected Hg low-pressure and medium-pressure UV radiators. To verify the calibration and to perform on-site tests, spectral measurements have been carried out directly at water disinfection plants in operation. The weighted microbicidal irradiance of the plants was calculated and compared to the measurements of various actinic radiometers.<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"_genesis_hide_title":false,"_genesis_hide_breadcrumbs":false,"_genesis_hide_singular_image":false,"_genesis_hide_footer_widgets":false,"_genesis_custom_body_class":"","_genesis_custom_post_class":"","_genesis_layout":"","footnotes":""},"categories":[308,51],"tags":[480,498,488,496],"class_list":{"0":"post-10303","1":"post","2":"type-post","3":"status-publish","4":"format-standard","6":"category-publications-and-reports","7":"category-research","8":"tag-irradiance_hi-en","9":"tag-oenorm-en","10":"tag-science-en","11":"tag-water-en-2","12":"entry"},"acf":[],"yoast_head":"\n2014 - Spectral Irradiance Measurement and Actinic Radiometer Calibration for UV Water Disinfection | sglux<\/title>\n<meta name=\"robots\" content=\"index, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\n<link rel=\"canonical\" href=\"https:\/\/sglux.de\/en\/2014-spectral-irradiance-measurement-and-actinic-radiometer-calibration-for-uv-water-disinfection-2\/\" \/>\n<meta property=\"og:locale\" content=\"en_US\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"2014 - Spectral Irradiance Measurement and Actinic Radiometer Calibration for UV Water Disinfection | sglux\" \/>\n<meta property=\"og:description\" content=\"P.
