Details

Titratable acidity is an important parameter in determining fruit maturity and sour taste in citrus fruits.The maturity of fruit is one of the most important factors to determine how well fruit will store andhow it will taste. For some fruits, governmental quality standards (based on titratable acidity or theratio of total soluble solids (°Brix) to titratable acidity) are in place to protect consumers. Immaturefruit will normally have a low sugar to acid ratio as compared to mature fruit that will have a high sugarto acid ratio.

The HI84532 measures the concentration of titratable hydrogen ions contained in fruit juice samples byneutralization with a strong base solution to a fixed pH. This value includes all the substances of anacidic nature in the fruit juice including: free hydrogen ions, organic acids and acid salts. Titratableacidity is expressed as g/100 mL of the predominant acid. The predominant acids in fruit depend on thetype of fruit being tested and include citric acid, tartaric acid, and malic acid.

Double Junction pH ElectrodeThe HI84532 is supplied with the HI1131B refillable, double junction, combination pH electrode. Bydesign, the HI1131B has a spherical tip for use in aqueous or liquid solutions. This versatile electrodeprovides a wide surface of contact with a sample and is ideal for direct measurements or titrations inthe beverage industry.

Custom pH CalibrationAccording to AOAC International the titration endpoint for fruit products is pH 8.1. The HI84532 usesa custom calibration point of pH 8.20. The preprogrammed pH 4.01 and pH 8.20 calibration pointsallows for calibration of the meter that brackets the pH readings.

Good Laboratory PracticeThe HI84532 offers comprehensive GLP information including date and time of the last pH electrodeand dosing pump calibrations. Tracking calibrations are critical to have confidence in the resultsobtained from titrations. The GLP data is stored along with any logged readings.

Piston Driven Dosing PumpThe heart of the HI84532 is the piston driven burette pump. This type of dosing system uses a motor inwhich each dose is very precisely controlled and the volume dispensed is accurately determined. Thistitrant is dynamically dosed, where titrant is delivered in larger doses at the start of the titration andsmaller doses near the end point. With larger doses in the beginning of the titration, the speed of thetitration is increased, where smaller doses near the end point allow for more time for the titrant andanalyte to react. Smaller doses also prevent the over titration of a sample and a more accuratedetermination of titrant volume used.

Automatic StirrerThe built-in stirrer is automatically maintained at a speed of 600 rpm, regardless of the viscosity of thesolution being titrated.

On-Screen Features

Easy-to-Use Interface The HI84532 has an intuitive user design with clearly defined keys and a largescreen that is easy to navigate. The meter has a built-in tutorial mode that, when enabled, will walk the

user step by step through the titration process. A dedicated HELP key is always available to allowaccess to content-specific information during both calibration and titration.

Procedure Warnings Users are warned if there is an error in procedures such as the titration exceededthe maximum volume of titrant.

Graphic Mode This mini titrator displays in-depth data during titration, including a real-time graph ofthe titration curve.

Log-on-Demand The HI84532 allows for data logging of up to 400 samples: 200 titration results and200 pH/mV readings. Data can be stored and exported to a USB drive or a PC using the USB

connection.

pH/mV Meter In addition to being an automatic titrator, the HI84532 also can be used as a pH/mVmeter. As a pH meter, it has many features of a professional grade benchtop including automatic

calibration up to three points with four available buffers, a 0.01 pH resolution, accuracy of ±0.01 pH,automatic temperature compensation and comprehensive GLP data.

CAL Check™ Accuracy is always ensured with Hanna’s unique CAL Check feature, which analyzesthe response of the electrode during the calibration process. Based on electrode response in the buffer,

indicators are displayed on screen to alert the user of potential problems during calibration. Theseindicators include Buffer Contaminated, Electrode Dirty/Broken, and overall probe condition. The CALCheck function not only ensures an accurate pH reading when the HI84532 is used as a pH meter, butalso an accurate titration since the endpoint of a titratable acidity titration is determined by a set pH

value.
