The user will then count how many drops of reagent were used to achieve complete colour change. The number of drops used will determine the chemical concentration and results can be found in the manual included.\u003c\/p\u003e \u003cp\u003e\u003cbr\u003e \u003cb\u003eChemical Method: EDTA; Weight: 460 g\u003c\/b\u003e\u003c\/p\u003e \u003cp\u003eRange: 0.0 to 30.0; 0 to 300 mg\/L\u003c\/p\u003e","brand":"Hanna Instruments","offers":[{"title":"Default Title","offer_id":57640059765109,"sku":"HI-3812-100","price":34.67,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0574\/5511\/6439\/files\/replacement-reagent-for-hardness.jpg?v=1791580054","url":"https:\/\/testallwater.co.uk\/products\/hanna-instruments-hi-3812-100-replacement-reagent-for-hardness","provider":"Test All Water","version":"1.0","type":"link"}
