Blue light from an LED illuminates the luminescent chemical. The luminescent chemical instantly becomes excited and releases red light. The time and intensity of red light are inversely proportional to the concentration of oxygen molecules, So the concentration of oxygen molecules is calculated.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch4 class=\"sub-title\"\u003eCharacteristics\u003c\/h4\u003e\n\u003cp\u003e\u003cspan\u003eRange: 0-20mg\/L,0-200%,0-400hPa\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eResolution: 0.01mg\/L,0.1%,1hPa\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eOutput signal: 4~20mA; Relay; RS485\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003ePower supply: AC220V±10%; 50Hz\/60Hz\u003c\/span\u003e\u003c\/p\u003e","brand":"BayMeters","offers":[{"title":"Default Title","offer_id":51928788861211,"sku":null,"price":1104.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0929\/2873\/7563\/files\/10.png?v=1774411147","url":"https:\/\/baymeters.com\/products\/sup-do700-optical-dissolved-oxygen-meter","provider":"BayMeters","version":"1.0","type":"link"}
