Hanna HI84529U-01 Mini Titrator for Measuring Titratable Acidity

Description

Precision Instrument for Dairy Acidity Analysis

The Hanna HI84529U‑01 Mini Titrator for Measuring Titratable Acidity is a compact, highly accurate, and user‑friendly benchtop device designed specifically for the dairy industry. It automates the acid‑base titration process to determine titratable acidity levels with unmatched speed and precision, making it ideal for quality control and routine testing in milk processing plants, cheese production facilities, yogurt manufacturing, and dairy research laboratories. This model employs an optimized pre‑programmed analysis method, featuring a specialized Foodcare low‑temperature pH electrode that ensures stability and accuracy in a wide range of dairy product types and temperatures. By employing a precision piston‑driven dosing pump system that dynamically adjusts titrant delivery, the instrument achieves accurate determinations while significantly reducing titration time. For laboratories focused on reproducibility, compliance with AOAC International and Standard Methods for the Examination of Dairy Products ensures that results meet industry standards and are comparable across operations.

Advanced Piston Dosing Ensures Exceptional Accuracy

At the heart of the HI84529U‑01 lies a precision piston burette dosing pump that dynamically alters delivery volumes based on electrode voltage feedback. This approach ensures rapid titrant addition at the start of analysis and increasingly precise micro‑dosing as the endpoint is approached, thereby minimizing overshoot and securing endpoint accuracy. The dosing volume and pump control are fully automated, eliminating manual variability. By integrating real‑time response optimization, titration processes become both faster and more reliable. Such precision is vital for dairy applications, where acidity directly impacts product flavor, shelf life, and compliance with legal standards. This dosing technology, combined with the instrument’s user interface, makes it a powerhouse for both small and large laboratories. It also supports sample preparation flexibility, handling diluted and undiluted samples in varying volumes and ranges, dictated by the expected acidity profile of the dairy product tested.

Flexible Ranges for Multiple Dairy Applications

The HI84529U‑01 supports multiple titration ranges—Low Range 20, Low Range 50, and High Range 20—enabling users to test various dairy products, from fresh milk and cream to concentrated milk solids and specialty products like condensed or evaporated milk. The low‑range options allow fine resolution measurements for fresh milk or yogurt acidity monitoring, while the high‑range option is suited for products with higher acid contents, such as fermented dairy specialties or ripened cheeses. Sample sizes can be titrated by weight or volume, providing versatility in laboratory procedures. For example, a 50 mL undiluted milk sample can be tested in Low Range 50 mode, while small volume, high‑acidity samples can be accurately analyzed in the High Range mode. Units of measurement such as % Lactic Acid, Degree Soxhlet Henkel (°SH), Degree Dornic (°D), and Degree Thorner (°Th) can be converted directly on the device using pre‑programmed factors, simplifying reporting in multi‑standard environments.

Comprehensive Electrodes for Accurate Dairy Titrations

The instrument is supplied with the FC260B half‑cell pH electrode, specifically engineered for dairy analysis using low‑temperature (LT) glass. LT glass offers about 50 megaohms resistance, ensuring accurate pH readings for chilled or refrigerated dairy samples, which can otherwise exhibit unstable readings with general‑purpose electrodes. This is coupled with the HI5315 reference half‑cell electrode, featuring a skirted cone junction and a plunger mechanism to remove any clogging that can occur due to fat or protein deposits in dairy samples. Together, these electrodes produce stable, reproducible measurements under challenging conditions, such as high‑fat cream titration or fermented milk testing. Furthermore, the reference electrode can be fully disassembled for deep cleaning, preserving measurement consistency and extending electrode lifespan—an essential factor for high‑throughput dairy production labs.

Built-In Intelligence and Laboratory Compliance

The HI84529U‑01 is designed for compliance and traceability under Good Laboratory Practice (GLP) guidelines. It stores calibration data for both the pH electrode and the dosing pump along with timestamps, ensuring traceability of results. Equipped with Hanna’s exclusive CAL Check™ feature, the device evaluates electrode performance during calibration and alerts users to possible issues such as contaminated buffers or damaged electrodes. This ensures that both pH measurements and titrations remain accurate. Graphic mode capability allows real‑time titration curve visualization, providing technicians with deeper insight into the reaction profile of the sample. With a data logging capacity of up to 400 records (200 titration results, 200 pH/mV readings) and USB data export capability, the HI84529U‑01 easily integrates into digital lab workflows, facilitating analysis documentation and regulatory compliance.

User-Friendly Design for Streamlined Testing

This mini titrator offers a clear, intuitive interface with dedicated keys, an on‑screen tutorial mode, and a HELP function for step‑by‑step procedural guidance—ideal for training new operators or ensuring consistent operation among multi‑shift laboratories. Procedure warnings prevent operational errors by alerting users when titration volumes exceed limits. The automatic stirrer operates at set speeds for different ranges—800 rpm for low‑range titrations and 1000 rpm for high‑range—to ensure homogeneous mixing throughout analysis, regardless of viscosity. The ergonomically designed beaker stand and probe holder keep electrodes and dosing tips in optimal positions, enhancing both workflow efficiency and safety. Laboratories benefit from reduced operator fatigue and minimized measurement variability, which is critical for production release testing or research experiments.

Wide Temperature Range and Robust Construction

Engineered to operate in laboratory environments from 0 to 50°C with relative humidity up to 95% (non‑condensing), the HI84529U‑01 is physically robust and functionally resilient. The FC260B electrode is suitable for samples between ‑5°C and 100°C, allowing direct analysis of both chilled milk and thermal‑processed dairy products. The stainless steel HI7662‑M temperature probe ensures precise automatic temperature compensation, critical for pH accuracy in temperature‑sensitive samples. Built to compact dimensions of 235 × 200 × 150 mm and weighing just 1.9 kg, the instrument saves bench space while remaining stable in operation. It includes all necessary reagents—standardized titrants, calibration solutions, and cleaning agents—pre‑packaged to ensure operator convenience and eliminate the need for volumetric glassware or weighing balances in most applications.
