These reagents follow the Colorimetric Method in which the reaction causes a distinctive range of colours from yellow to green to blue to develop. By simply adding one drop of the Chlorine Remover to remove the chlorine interference, and subsequently adding 1 mL of the Alkalinity Reagent to the sample, the reaction will take place and the HI-775 will determine the concentration from the colour that is produced. The results will be displayed in ppm of CaCO\u003csub\u003e3\u003c\/sub\u003e. These reagents are designed to be used with samples that have an expected range of 0 to 500 ppm CaCO\u003csub\u003e3\u003c\/sub\u003e.\u003c\/p\u003e","brand":"Hanna Instruments","offers":[{"title":"Default Title","offer_id":56177678844283,"sku":"HI-775-26","price":34.91,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0563\/6387\/6487\/files\/HI775_66a3bbc1-20a7-405c-9b58-6ac2b36efe69.jpg?v=1774610324","url":"https:\/\/charterhouse-aquatics.com\/products\/hanna-hi-775-26-freshwater-alkalinity-reagents-25-tests","provider":"Charterhouse Aquatics","version":"1.0","type":"link"}
