Product Description

The HI 84432 is a microprocessor-based, automatic minititrator and pH meter suitable for analyzing Total Titratable Acidity in fruit juices. It features a simple peristaltic pump to ensure accuracy. The instrument employs a built-in algorithm to analyze the pH response to determine the exact pH endpoint, then uses this to make necessary calculations. The Titratable Acidity Determination is displayed instantaneously in user-selected measurements on the large dot matrix display. The meter calibrates pH at up to three points using three buffers (4.01, 7.01, 8.20). It features Manual or Automatic Temperature Compensation, and can log up to 100 samples (50 for pH measurement; 50 for titration results). The electrodes and probe are replaceable, prolonging the life of the meter, and Good Laboratory Practice (GLP) features allow user to view last calibration data for pH electrode and pump.

Range is -2.0 to 16.0; -2.00 to 16.00 pH + or - 0.01 pH, with a resolutions 0.1; 0.01 pH. Temperature range is -20.0 to 120.0 degrees C (-4.0 to 248 degrees F) + or – 0.4 degrees C (excluding probe error) at 20 degrees C, with a resolution of 0.1 degrees C. The device operates on a 12 VDC power adapter. Dimensions are 208 x 214 x 163 mm/8.2” x 8.4” x 6.4’’ (H x W x D) with beaker, and weighs 2200 g (77 oz.).

Titratable acidity of fruit is an important parameter in determining fruit maturity. The measurement of titratable acidity in fruit juices measures the concentration of titratable hydrogen ions contained in the fruit samples by neutralization with strong base solution to a fixed pH. This value includes all the substances of an acid nature in the fruit juice—free hydrogen ions, organic acids, acids, and cathions. These instruments are commonly used in agricultural industries, and by manufacturers and researchers.

Hanna Instruments manufactures analytical instrumentation and supplies, including pH meters, electrodes, chemical reagents, and buffer solutions. The company, founded in 1978 and headquartered in Woonsocket, RI, meets International Organization for Standardization (ISO) 9001 standards.
