Hi, I am Businessman I found this sample from https://www.indotrade.co and think it might be useful to you. ------------------------------------------------------- HANNA, HI 84432 Titratable Acidity Mini Titrator & pH Meter for Fruit Juices The HI 84432 is an easy to use microprocessor-based automatic minititrator and pH meter designed for the rapid and accurate analysis of Total Titratable Acidity in fruit juices. By eliminating subjective factors including color indicators, errors in mathematical calculations or erratic titrant additions from the measurement, the HI 84432 makes Total Titratable acidity analysis precisely. This will quickly become a valuable acidity analysis tool of fruit juices. The instrument benefits from Hanna’ s many years of experience as manufacturer of quality analytical instruments. A clear and well-designed user interface makes the instrument intuitive and simple to use. A dedicated HELP key aids in set-up, calibration, status and troubleshooting. By simply pressing the START key, the HI 84432 automatically starts pump operation and titrates the sample to the end point. The HI 84432 has a simple and accurate peristaltic pump to ensure the best accuracy and repeatability. By performing pump calibration with the Hanna standard provided, the instrument accuracy is assured. The instrument employs a powerful and effective built-in algorithm to analyze the pH response to determine the exact pH endpoint, then uses this to make the necessary calculations. The Titratable Acidity determination is instantaneously displayed in selected measurement units on the large dot matrix display. The instrument is ready for the next analysis immediately. Other features: • Log on demand up to 100 samples ( 50 for pH measurement; 50 for titration results) • GLP feature, to view last calibration data for pH electrode and pump MEASUREMENT SIGNIFICANCE Titratable acidity of fruit juices measures the concentration of titratable hydrogen ions contained in the fruit juices samples, by neutralization with strong base solution at fixed pH. This value includes all the substances of an acidic nature in the fruit juice: free hydrogen ions, organic acids, acid salts and cathions. Because the organic acid is the most acidic component of the fruit juices that react with strong bases solutions, the titratable acidity is usually expressed as g/ L or g/ 100mL of the predominant acid contained: • Citric acid is present in many fruits species. • Tartaric acid is essentially found in grapes. • Malic acid is present in many fruit species, sometimes together with citric acid or tartaric acid in unripe grapes. Titratable acidity of fruit is an important parameter in determining fruit maturity. Fruits, juices Titratable acidity ( g/ 100mL) Predominant acid Apple, pear 0.36-0.80 Malic acid Cranberry 1.6-3.6 Citric acid Grapefruit 1.2-2.0 Citric acid Lemon 4-6.2 Citric acid Mango 0.34-0.84 Citric acid Orange 0.8-1.4 Citric acid Peach, nectarine, sweet cherry 0.24-0.94 Citric acid Pineapple 0.7-1.6 Citric acid Plum/ Sour cherry 0.94-1.64 Malic acid Strawberry 0.6-1.1 Citric acid Table grape 0.4-0.9 Tartaric acid Tomato 0.34-1.00 Citric acid The HI 84432 minititrator uses a method based on the Official Methods of Analysis of AOAC International. The fruit juice is titrated with a sodium hydroxide solution until the end point at 8.2 pH is reached ( determined by potentiometric method) . Additionaly the HI 84432 has a built-in pH meter for pH measurement ( electrode and meter must be calibrated) . Range Titrator g/ 100 mL as citric acid : 0.20 - 8.00% CA g/ 100 mL as tartric acid : 0.23 - 9.30% TA g/ 100 mL as malic acid : 0.21 - 8.30% MA Resolution Titrator 0.01% Accuracy Titrator 5% of reading ± 0.05 Titration method Titrator Acid-base titration Principle Titrator End point titration : 8.20 pH Pump debit Titrator 0.5 mL/ min Stirring speed Titrator 600 rpm Log data Titrator Up to 50 samples Range pH -2.0 to 16.0 pH / -2.00 to 16.00 pH Resolution pH 0.1 pH / 0.01 pH Accuracy pH ± 0.01 Ph Calibration pH 1, 2 or 3 calibration points; 3 available buffers ( 4.01; 7.01; 8.20) Temperature compensation pH manual or automatic from -20 to 120 ° C ( -4 to 248 ° F) Log data pH Up to 50 samples Range Temperature -20.0 to 120.0 ° C ( -4.0 to 248.0 ° F) Resolution Temperature 0.1 ° C Accuracy Temperature ± 0.4 ° C without probe error Electrode HI 1131B ( included) Temperature Probe HI 7662-M ( included) Environment 0 to 50 ° C ( 32 to 122 ° F) ; max 95% RH non-condensing Power supply 12 Vdc power adapter Dimensions 208 × 214 × 163 mm ( 8.2× 8.4× 6.4" ) ( with beaker) Weight 2200 g ( 77 oz.)
