{"id":76,"count":1,"description":"In our turbidity measurement category, we offer solutions optimised to measure and monitor the particle content of liquids with high precision. Our turbidity meters are especially suited for applications in water treatment, breweries, food production and process industries where it is crucial to ensure liquid quality. The products are equipped with robust optical systems that deliver accurate measurements even under challenging conditions, making it possible to monitor and control processes to achieve the highest possible efficiency and quality.","link":"https:\/\/www.omniprocess.se\/en\/produkt-kategori\/vatskeanalys\/turbiditetsmatning\/","name":"Turbidity measurement","slug":"turbidity-measurement","taxonomy":"product_cat","parent":18,"meta":{"details":"

Vad \u00e4r turbiditetsm\u00e4tning?<\/span><\/b>\u00a0<\/span><\/h2>\r\nTurbiditet beskriver hur grumligt ett vattenprov \u00e4r \u2013 allts\u00e5 hur mycket ljus som sprids eller absorberas av suspenderade partiklar. Ju fler och\/eller st\u00f6rre partiklar, desto h\u00f6gre turbiditet. F\u00f6r dricksvatten anv\u00e4nds grumligheten som en snabb indikator p\u00e5 filtreringens effektivitet och p\u00e5 om patogener kan finnas kvar.<\/span>\u00a0<\/span>\r\n

    M\u00e4tpraxis vid turbiditetsm\u00e4tning<\/span><\/b>\u00a0<\/span><\/h2>\r\n
      \r\n \t
    1. Kalibrera regelbundet<\/span><\/b> med f\u00e4rska formazin-standarder (0\u2013800 NTU).<\/span>\u00a0<\/span><\/li>\r\n \t
    2. Reng\u00f6r kuvettens glas<\/span><\/b> och anv\u00e4nd silikonolja f\u00f6r att undvika repor som p\u00e5verkar ljusspridningen.<\/span>\u00a0<\/span><\/li>\r\n \t
    3. Undvik bubblor<\/span><\/b> \u2013 vrid l\u00e5ngsamt p\u00e5 provet eller avgasera l\u00e4tt.<\/span>\u00a0<\/span><\/li>\r\n \t
    4. M\u00e4t inom 30 min<\/span><\/b> efter provtagning s\u00e5 att partiklar inte sedimenterar.<\/span>\u00a0<\/span><\/li>\r\n \t
    5.
