The maturity of fruit is one of the most important factors to determine how well fruit will store and how it will taste. For some fruits, governmental quality standards (based on titratable acidity or the ratio of total soluble solids (°Brix) to titratable acidity) are in place to protect consumers. Immature fruit will normally have a low sugar to acid ratio as compared to mature fruit that will have a high sugar to acid ratio.\u003c\/p\u003e\n\u003cp\u003eThe HI84532 measures the concentration of titratable hydrogen ions contained in fruit juice samples by neutralization with a strong base solution to a fixed pH. This value includes all the substances of an acidic nature in the fruit juice including: free hydrogen ions, organic acids and acid salts. Titratable acidity is expressed as g\/100 mL of the predominant acid. The predominant acids in fruit depend on the type of fruit being tested and include citric acid, tartaric acid, and malic acid.\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\/juice-acid-types.jpg\" alt=\"juice acid types and titratable acidity\" 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\u003ch5 style=\"margin-top: 0;\"\u003e\u003cstrong\u003eDouble Junction pH Electrode\u003c\/strong\u003e\u003c\/h5\u003e\n\u003cp\u003eThe HI84532 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 titrations in the beverage industry.\u003c\/p\u003e\n\u003ch5\u003eCustom pH Calibration\u003c\/h5\u003e\n\u003cp\u003eAccording to AOAC International the titration endpoint for fruit products is pH 8.1. The HI84532 uses a custom calibration point of pH 8.20. The preprogrammed pH 4.01 and pH 8.20 calibration points allows for calibration of the meter that brackets the pH readings.\u003c\/p\u003e\n\u003ch5\u003eGood Laboratory Practice\u003c\/h5\u003e\n\u003cp\u003eThe HI84532 offers comprehensive GLP information including date and time of the last pH electrode and dosing pump calibrations. Tracking calibrations are critical to have confidence in the results obtained from titrations. The GLP data is stored along with any logged readings.\u003c\/p\u003e\n\u003ch5\u003ePiston Driven Dosing Pump\u003c\/h5\u003e\n\u003cp\u003eThe heart of the HI84532 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. This titrant is dynamically dosed, where titrant is delivered in larger doses at the start of the titration and smaller doses near the end point. With larger doses in the beginning of the titration, the speed of the titration is increased, where smaller doses near the end point allow for more time for the titrant and analyte to react. Smaller doses also prevent the over titration of a sample and a more accurate determination of titrant volume used.\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\u003c\/div\u003e\n\u003cdiv style=\"display: flex; flex-wrap: wrap; align-items: center; justify-content: center; gap: 24px 48px; margin: 0 0 48px; flex-direction: row-reverse;\"\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 HI84532 has an intuitive user design with clearly defined keys and a large screen that is easy to navigate.
