This can then lead to incorrect results. The respective tests should therefore be checked against a stable standard on a regular basis.\u003c\/span\u003e\u003cb\u003e\u003c\/b\u003e\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cspan\u003eTropic Marin® Multi-Standard is a solution, produced in the laboratory, and tested by means of ICP-OES. The solution is made with measured concentrations of calcium, magnesium, potassium and KH\/ alkalinity. It can be used to check the accuracy of test kits for those parameters and to calculate a correction factor, if the test kit is found to have a variance.\u003c\/span\u003e\u003cb\u003e\u003c\/b\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli dir=\"ltr\" aria-level=\"1\"\u003e\n\u003cp dir=\"ltr\" role=\"presentation\"\u003e\u003cspan\u003eA simple check of the functionality and accuracy of seawater tests\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli dir=\"ltr\" aria-level=\"1\"\u003e\n\u003cp dir=\"ltr\" role=\"presentation\"\u003e\u003cspan\u003eJust one standard to check the accuracy of several tests (calcium, magnesium, potassium and KH)\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli dir=\"ltr\" aria-level=\"1\"\u003e\n\u003cp dir=\"ltr\" role=\"presentation\"\u003e\u003cspan\u003eWorks with all common tests available on the market\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli dir=\"ltr\" aria-level=\"1\"\u003e\n\u003cp dir=\"ltr\" role=\"presentation\"\u003e\u003cspan\u003eThe test can continue to be used by calculating a correction factor.\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TMC","offers":[{"title":"Default Title","offer_id":57539340009845,"sku":"619106281505","price":13.95,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0821\/6353\/files\/Tropic-Marin-Multi-Standard-250ml-6337.jpg?v=1788273075","url":"https:\/\/www.e-marineaquatics.co.uk\/products\/tropic-marin-multi-standard-250ml","provider":"Essex Marine Aquatics","version":"1.0","type":"link"}
