Hanna HI84532U-01 Mini Titrator for Measuring Titratable Acidity in Fruit Juice

Description

Precision Instrument for Fruit Juice Analysis

The Hanna HI84532U‑01 Mini Titrator is an advanced, fast, and highly accurate analytical device specifically engineered for the measurement of both pH and titratable acidity in fruit juice samples. Designed for beverage laboratories, wineries, juice manufacturers, and professional quality control teams, this instrument simplifies the critical process of acidity analysis using optimized pre‑programmed methods and a professional‑grade glass pH electrode. By leveraging dynamic dosing technology, it ensures rapid yet precise titration performance, delivering reliable results even for demanding analytical environments. The complete kit includes all the components necessary for titratable acidity determination according to AOAC International standards, from electrodes to calibration solutions, ensuring immediate operation out‑of‑the‑box. Due to its integrated pH/mV measurement capabilities, the HI84532U‑01 doubles as a benchtop pH meter, making it a versatile addition to any food science or beverage testing laboratory.

Optimal Applications in Fruit Quality Testing

The HI84532U‑01 is particularly valuable in determining fruit maturity and flavor profile, as titratable acidity directly influences taste perception—especially the sourness associated with citrus fruits. This parameter also plays a vital role in storage stability, as acid balance impacts shelf life and overall freshness. In professional settings, such as small and medium wineries, juice processing facilities, and quality control laboratories, this mini titrator is used to measure the acidity of fruits including, but not limited to, lemons (4–6.2 g/100 mL citric acid), oranges (0.8–1.4 g/100 mL citric acid), grapefruit, apples, peaches, plums, and grapes. Each fruit type has a predominant organic acid—citric, tartaric, or malic—which the instrument accurately quantifies by neutralizing acidic components with a strong base to a precise endpoint pH. Regulatory authorities often require testing according to acidity‑to‑sugar ratios, and the HI84532U‑01’s reproducible accuracy makes it indispensable for meeting such compliance standards.

Advanced Titration Technology with Dynamic Dosing

At the heart of the HI84532U‑01 lies a piston‑driven burette pump that ensures meticulous control over the volume of titrant dispensed. The system uses dynamic dosing—delivering larger titrant volumes during the initial titration phase and progressively smaller doses approaching the endpoint. This approach accelerates the process while preventing overshooting, achieving a more accurate determination of acid content. The dosing is supported by a pump speed of 10 mL/min and an automatic 600 rpm stirrer, guaranteeing uniform mixing regardless of sample viscosity. Calibrations of the pump, performed with supplied Hanna standards, maintain ongoing precision and reliability. This engineering excellence ensures measurement accuracy within ± 0.02 % CA or 3 % of reading, ensuring laboratory‑grade results for both low‑range and high‑range titration modes.

Dual Functionality with Professional‑Grade pH Measurement

Beyond titration, the HI84532U‑01 functions as a high‑performance benchtop pH/mV meter with selectable pH resolution of 0.1 or 0.01 pH and an accuracy of ± 0.01 pH. It supports one‑, two‑, or three‑point calibration using four available buffer standards (4.01, 7.01, 8.20, and 10.01). The included HI1131B refillable double junction glass electrode is optimized for liquid and aqueous solutions, delivering stable and repeatable results. The unit’s CAL Check™ feature, unique to Hanna Instruments, evaluates electrode condition during calibration and alerts the user to potential issues such as buffer contamination or electrode fouling. With manual or automatic temperature compensation via the HI7662‑T stainless steel temperature probe, every reading reflects the true acidity state of the sample under test conditions.

User‑Centric Design with Comprehensive Interface

The HI84532U‑01 integrates an easy‑to‑navigate interface, a large LCD display, and clearly labeled keys for streamlined operation. A built‑in tutorial mode guides users, step by step, through calibration and titration, making it suitable for both experienced lab technicians and advanced hobbyists. On‑screen warnings help avoid procedural errors, such as exceeding the maximum titrant volume. Additionally, the system can display the titration curve in real time, enabling immediate visual assessment of reaction progress. All operational data, including calibration records, are preserved under Good Laboratory Practice (GLP) guidelines, reinforcing traceability and quality assurance in critical testing workflows.

Data Logging, Connectivity, and Export Capabilities

Data management with the HI84532U‑01 is highly efficient, featuring storage for up to 400 total sample records—200 for titration and 200 for pH/mV measurements. Users can log results on demand, recall historical measurements, and even export datasets via the built‑in USB interface to a USB drive or PC for further analysis or archival purposes. The ability to manage and retrieve past results supports trend analysis, regulatory documentation, and scientific reporting. Such capabilities make this instrument ideal not only for immediate operational testing but also for longitudinal research and quality assurance programs in the beverage and fruit processing industries.

Reliable Operation Across Laboratory Environments

Built for durability and consistent performance, the HI84532U‑01 functions optimally within environmental parameters of 0 to 50 °C and up to 95 % non‑condensing humidity. Compact and lightweight, with dimensions of 235 × 200 × 150 mm and a weight of 1.9 kg, the titrator fits efficiently in any lab setup. It is powered by a standard 12 VDC adapter and is supplied as a complete kit with electrode, temperature probe, reagent kits for both low and high titration ranges, beakers, tubes, dosing accessories, and a quality certificate. With a two‑year warranty, the HI84532U‑01 assures users of long‑term reliability, especially when sourced through a trusted supplier.
