The reagent is then added under monitored conditions.\u003c\/p\u003e \u003cp\u003eThe HI-3811-100 is the replacement reagent set for the HI-3811 Alkalinity test kit.\u003c\/p\u003e \u003cp\u003eDuring testing, when colour change is achieved, under careful conditions - usually using a burette – the reagent is added, drop by drop, until the solution turns clear. The user will then count how many drops of reagent were used to achieve complete colour dispersal. 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\u003eOrder Information:\u003c\/b\u003e\u003c\/p\u003e \u003cp\u003eReagent kit for 100 tests (CaCO\u003csub\u003e3\u003c\/sub\u003e).\u003c\/p\u003e","brand":"Hanna Instruments","offers":[{"title":"Default Title","offer_id":57640059699573,"sku":"HI-3811-100","price":51.02,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0574\/5511\/6439\/files\/replacement-reagent-for-alkalinity.jpg?v=1791580051","url":"https:\/\/testallwater.co.uk\/products\/hanna-instruments-hi-3811-100-replacement-reagent-for-alkalinity","provider":"Test All Water","version":"1.0","type":"link"}
