An immobilised Pt-based luminophore is excited by the light of a blue LED and emits a red light. As oxygen interacts with the luminophore it reduces the intensity and lifetime of the luminescence. The lifetime of the luminescence is measured by a photodetector and is used to calculate the dissolved oxygen concentration.\u003c\/p\u003e","brand":"Hanna Instruments","offers":[{"title":"Default Title","offer_id":52137764389211,"sku":"HI-7641133","price":875.95,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0978\/9204\/1051\/files\/3110.jpg?v=1769766967","url":"https:\/\/hannainst.se\/en-dk\/products\/hi-7641133-optical-dissolved-oxygen-opdo-probe","provider":"HannaNorden AB","version":"1.0","type":"link"}
