Titratable acidity mini titrator and pH meter is an easy to use automatic mini titrator and pH meter designed for the rapid and accurate analysis of titratable acidity in mayonnaise. By eliminating subjective factors including color indicators, errors in mathematical calculations or erratic titrant additions from the measurement, the HI 84437 makes titratable acidity analysis precise. This instrument will quickly become a valuable tool for mayonnaise analysis. A clear and intuitive user interface allows users to navigate the HI 84437's menus and functions quickly. A help key located on the keypad aids in set-up, calibration status and troubleshooting. Simply weigh the sample, dilute with water and press start. The HI 84437 automatically stirs the sample, starts pumps operation and titrates the sample to the endpoint. 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. Titratable acidity determination is instantaneously displayed in the selected measurement unit on the display. The instrument is then immediately ready for the next analysis. The HI 84437 employs a simple peristaltic pump to ensure the best accuracy and repeatability in measurements. To ensure the most consistent results, pump calibrations can be performed with the provided Hanna standard. It is supplied with pH electrode, temperature probe, titrant solution (100mL), pump calibration solution (100mL), pH 4.01 buffer solution (230mL), pH 7.01 buffer solution (230mL), pH 8.20 buffer solution (230mL), 100mL beakers (2), tube set with dispensing tip, medium magnetic stir bars (2), 12 VDC adapter and instruction manual. Titratable acidity range: g/100 g as acetic acid : 0.16 - 1.60 percent AA, g/L (ppt) as acetic acid : 1.6 - 16.0 g/L (ppt) AA. Resolution: 0.01 percent AA; 0.1 g/L (ppt) AA. Accuracy (at 25 degree C/77 degree F): 5 percent of reading.
