It is formulated for accurate calibration of pH meters and electrodes and is particularly useful when testing samples expected to have a near-neutral pH. The solution is red colour-coded for easy identification and provides an accuracy of ±0.01 pH at 25°C. \u003cspan class=\"contents\"\u003e\u003cspan class=\"\"\u003e\u003c\/span\u003e\u003c\/span\u003e\u003cspan class=\"PDq2pG_selectionAnchor\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eHanna prepares its calibration buffers using high-purity salts, deionized water, certified balances and Class A glassware under controlled conditions.
