Total titratable alkalinity is a measure of primarily three types of alkalinities present in a water sample: hydroxides, carbonates, and bicarbonates. Alkalinity in water can be the result of contributions from common chemicals including carbonates, bicarbonates, hydroxides, phosphates, borate and organic acid salts.\u003c\/p\u003e\n\u003cp\u003eThe alkalinity of a water sample indicates its ability to resist pH change. The amount of alkalinity in water is mostly due to the bicarbonate\/carbonate present. A low alkalinity level indicates that the water is susceptible to pH changes, while a high alkalinity level indicates that the water will be able to resist pH changes. Alkalinity can also be used to determine the corrosive capacity of water and can provide an estimation of water hardness.\u003c\/p\u003e\n\u003ch5\u003eDouble Junction pH Electrode\u003c\/h5\u003e\n\u003cp\u003eThe HI84531 is supplied with the HI1131B refillable, double junction, combination pH electrode. By design, the HI1131B has a spherical tip for use in aqueous or liquid solutions. This versatile electrode provides a wide surface of contact with a sample and is ideal for direct measurements or acid base titrations in the water industry.\u003c\/p\u003e\n\u003ch5\u003ePiston Driven Dosing Pump\u003c\/h5\u003e\n\u003cp\u003eThe heart of the HI84531 is the piston driven burette pump. This type of dosing system uses a motor in which each dose is very precisely controlled and the volume dispensed is accurately determined. The piston driven burette is controlled dynamically so that the volume of titrant being dosed is automatically adjusted based on a voltage response of the previous dose. This type of dosing speeds up the titration process by allowing for more titrant to be dosed at the start of the titration and then very small doses as the endpoint is reached.\u003c\/p\u003e\n\u003ch5\u003eAutomatic Stirrer\u003c\/h5\u003e\n\u003cp\u003eThe built-in stirrer is automatically maintained at a speed of 600 rpm, regardless of the viscosity of the solution being titrated.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"display: flex; flex-wrap: wrap; align-items: center; justify-content: center; gap: 24px 48px; margin: 0 0 48px;\"\u003e\n\u003cdiv style=\"flex: 1 1 260px; max-width: 440px; text-align: center;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/HI84532-Help.jpg\" alt=\"titrator screenshot\" loading=\"lazy\" style=\"display: block; max-width: 100%; height: auto; margin: 0 auto;\"\u003e\u003c\/div\u003e\n\u003cdiv style=\"flex: 1 1 340px; min-width: 0;\"\u003e\n\u003ch4 style=\"margin-top: 0;\"\u003eOn-Screen Features\u003c\/h4\u003e\n\u003cp\u003e\u003cstrong\u003eEasy-to-Use Interface\u003c\/strong\u003eThe HI84531 has an intuitive user design with clearly defined keys and a large screen that is easy to navigate.
