Automatic potentiometric titrator

Superior design for superior results.

The Cycoloy® body is durable, heat-resistant, and resists staining. Menu buttons are part of the display making it fully sealed and easy to clean. A high contrast LCD display makes every character on the display stand out and the wide viewing angle allows measurements to be seen from any angle. The backlight is adjustable for perfect viewing and a backlight saver option protects the display during periods of inactivity.

Maximize your workspace.

This new generation of titrator features a 50% smaller footprint than the HI901 Automatic Titrator for maximum use of your lab space. Use it in any sized space while providing accurate and consistent results.

Simple User Experience

Virtual keys present on the display allow for simple and quick navigation between screens and menus without getting lost in a nest of information. If you need additional information about a screen, simply press the dedicated button for help.

Multiple Titration Types

Paired with the right electrode, this potentiometric titrator can perform any number of standard titrations including pH and mV tests with fixed endpoints or single equivalence points.


Track Your Progress

A real-time titration curve can be displayed during each titration; this feature is useful when new methods are tested or when a procedure requires optimization.

Enhanced Security Options

Administrative users can set a PIN code on the device protecting against unauthorized access. Titration method options and results are tamper-proof while a non-administrator operates the titrator, ensuring records remain safe, secure, and traceable.

Exchangeable Burette System

With Hanna’s Clip-Lock™ burette feature, it only takes a few seconds to exchange titrants and reagents preventing cross-contamination and saving time.

Precision Dosing Pump

Our unmatched 40,000-step piston driven pump is capable of dosing extremely small and highly accurate volumes of titrant or reagent.

Chemically Resistant Tubing

Aspiration and dispensing tubes are constructed of durable, chemically resistant PTFE and feature a light-blocking polyurethane outer sleeve to protect light sensitive reagents.

Flexible Electrode Holder

This electrode holder can hold up to 3 electrodes, 4 tubes, and 1 temperature probe at any given time. The holder is angled and the stirrer is removable for access to smaller volume titrations without hassle. Use electrodes with different diameters when needed simply by changing the electrode guide. No need to move electrodes around, get the best tube alignment for your titration with a rotating holder.

Adjustable Arm

For a more compact design, the electrode holder is built directly into the titrator body. The press-to-release button makes for simple height control. Need to save more space? Just reverse the holder to accommodate larger beakers.

Smarter Stirring

The removable overhead stirrer has built-in speed control for more consistent stirring.

Take advantage of the versatility.

HI931 functions as a titrator, pH meter, mV/ORP meter, and ISE meter. Valuable laboratory bench space is saved, and multiple tests can be performed on one sample.

Stay connected.

Connect the devices that help you most, whether it be an analytical balance for automatic weight sample entry or a printer for your reports.

View and print reports easily.

You can print reports directly from the titrator with a connected printer.

Designed for dynamic environments.

Don’t worry about small spills in the laboratory with built-in spill handling. An external gutter system protects important connections and interior trays safeguard internal electronics.

Automatic Reagent Addition

A peristaltic pump may be programmed to volumetrically dispense reagent prior to titration or direct measurement or aspirate post-analysis. This helps achieve consistent and accurate results and prevents operator errors such as incorrect volumes or forgetting reagent addition.

Automatic potentiometric titrator

Customizable Analysis Reports

Each analysis report is fully customizable so users can ensure they are storing and filing the best data required for their application. New multiselect feature makes batch processing simple.

Flexible GLP Management

All necessary GLP (Good Laboratory Practice) information is recorded with each sample including sample identification, company and operator name, date, time, electrode ID codes, and calibration information.

Effortless Data Transfer

A conveniently located USB port or direct connection to a PC allows for the transfer of titration methods, titration reports, and software upgrades. Easily convert titration methods from our software to an LIMS friendly format.
