Test Salt and Acidity in Food Products with Confidence

From titration to table, create a tasty food product every time. Salt and acidity are critical factors in ensuring the quality, consistency, and safety of food products. Our Automatic Titrator uses a linked analysis method to measure both salt and acidity in a single sample, delivering fast, accurate results in just minutes. Comply with standards easily, streamline your QC processes faster, and avoid product recalls with an Automatic Titrator in-house.

Superior Design for Reliable Results

The Hanna Instruments HI931 Automatic Potentiometric Titrator is engineered with a rugged Cycoloy® body that resists heat, staining, and wear, ensuring long-term durability in demanding laboratory environments. Its fully sealed interface integrates menu buttons directly into the display, making the unit easy to clean and resistant to spills. A high-contrast LCD with wide viewing angles and adjustable backlighting guarantees clear visibility of every measurement, while the backlight saver protects the screen during idle periods. This thoughtful design delivers both reliability and efficiency, helping laboratories achieve consistent titration results with confidence.

Multiple Titration Types

The HI931 Automatic Potentiometric Titrator supports a wide range of standard titrations. Pair with the appropriate electrode to run pH and mV measurements using fixed endpoints or single equivalence points, enabling versatile workflows across acids, bases, and redox applications.

Track Your Progress

View a real‑time titration curve as the analysis proceeds. This visualization helps optimize new methods, troubleshoot procedures, and confirm endpoints for consistent, repeatable results.

Enhanced Security Options

Administrative PIN control protects method settings and results from unauthorized changes. While non‑administrators operate the instrument, titration options and records remain tamper‑proof, ensuring traceability and data integrity.

Exchangeable Burette System

Hanna’s innovative Clip‑Lock™ burette design allows rapid exchange of titrants and reagents in just seconds. This prevents cross‑contamination, reduces downtime, and keeps your titration workflow efficient and reliable.

Precision Dosing Pump

The HI931 Automatic Potentiometric Titrator features a 40,000‑step piston‑driven dosing pump capable of delivering extremely small, highly accurate volumes of titrant. This ensures precise endpoints and unmatched consistency across repeated analyses.

Chemically Resistant Tubing

Built with durable PTFE aspiration and dispensing tubes, the system resists harsh chemicals while a polyurethane outer sleeve blocks light to protect sensitive reagents. This robust design guarantees long‑term reliability in demanding laboratory environments.

Flexible Electrode Holder

The HI931 Automatic Potentiometric Titrator includes a versatile electrode holder capable of supporting up to three electrodes, four tubes, and one temperature probe simultaneously. Its angled design and removable stirrer make it easy to handle small‑volume titrations while maintaining precise alignment for consistent results.

Adjustable Arm

Built directly into the titrator body, the adjustable arm saves bench space and simplifies sample handling. A press‑to‑release button allows quick height control, while the reversible holder accommodates larger beakers for maximum flexibility in laboratory workflows.

Smarter Stirring

The removable overhead stirrer features integrated speed control, ensuring uniform mixing and reproducible titration conditions. This intelligent design improves accuracy and reliability across a wide range of applications.

Take Advantage of Versatility

The HI931 Automatic Potentiometric Titrator functions as a titrator, pH meter, mV/ORP meter, and ISE meter all in one compact instrument. This multi‑purpose design saves valuable bench space while allowing multiple analyses to be performed on a single sample.

Stay Connected

Easily connect essential devices such as an analytical balance for automatic sample weight entry or a printer for generating detailed reports. The HI931 integrates seamlessly with your lab setup to streamline workflows.

View and Print Reports Easily

Reports can be printed directly from the titrator when connected to a printer, ensuring fast documentation and traceable records for compliance and quality assurance.

Customizable Analysis Reports

The HI931 Automatic Potentiometric Titrator allows users to tailor every analysis report to their specific needs. With batch processing and multi‑select features, laboratories can streamline data management while ensuring critical information is captured for compliance and review.

Flexible GLP Management

All essential Good Laboratory Practice (GLP) details are automatically recorded with each sample, including operator name, company, date, time, electrode ID codes, and calibration data. This ensures traceability and supports rigorous quality standards.

Effortless Data Transfer

A conveniently located USB port and PC connectivity make it simple to transfer titration methods, reports, and software upgrades. Data can be easily converted into LIMS‑friendly formats, integrating smoothly with laboratory information systems.
