All Hanna ISE standard solutions are manufactured with high purity chemicals.\u003c\/p\u003e\u003cp\u003eISEs require calibration for accurate readings. Calibration of up to two points is recommended for enhanced accuracy. ISE calibration standards and sample solutions should always have the same ionic strength; the exact volume of ionic strength adjuster (ISA) must be added to all standards and samples prior to measurement.\u003c\/p\u003e","brand":"Hanna Instruments","offers":[{"title":"Default Title","offer_id":57640061927797,"sku":"HI-4005-01","price":117.32,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0574\/5511\/6439\/files\/0-1-m-carbon-dioxide-standard.jpg?v=1791580130","url":"https:\/\/testallwater.co.uk\/products\/hanna-instruments-hi-4005-01-0-1-m-carbon-dioxide-standard-500-ml","provider":"Test All Water","version":"1.0","type":"link"}
