The results will be displayed in ppm of calcium. These reagents are designed to be used with samples that have an expected range of 200 to 600 ppm calcium.\u003c\/p\u003e","brand":"Hanna Instruments","offers":[{"title":"Default Title","offer_id":57054566875467,"sku":"HANNA-HI-758-26","price":29.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1033\/7065\/4027\/files\/i_m_image_12049_4.jpg?v=1776423594","url":"https:\/\/krakencorals.co.uk\/products\/hanna-reagent-calcium","provider":"Kraken Corals","version":"1.0","type":"link"}
