Titration Capabilities

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.

Dynamic Titrant Dosing

The dynamic dosing feature allows for timely and accurate titration results by relating the titrant volume dosed to the mV response from the titration reaction. This provides for larger doses near the beginning of a titration and smaller, more precise doses near the titration endpoint.

Equivalence Endpoint Detection

Equivalence endpoint detection is critical in applications where fixed endpoints are not specified in standard methods. This endpoint indicates where the mV response from the titration is greatest with respect to the volume of titrant dosed.

Signal Stability Timing

The signal stability feature monitors when the mV response of the titration reaction stabilises before providing the next titrant dose. This ensures reliable measurement values throughout the length of a titration.

Customisable Methods

This titrator can store up to 15 user-defined or standard titration and direct measurement methods. Each method may be modified and optimised for performance based on application and user requirements.

Customisable Analysis Reports

Each analysis report is fully customisable to ensure the best data required for an application is stored and filed. The Multi-select feature makes batch processing simple.

Burettes and Dosing System

Clip Lock™ 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.

Multiple Burette Sizes

HI-930 is supplied with a 10 mL burette but may be equipped with a 5 mL, 25 mL, or 50 mL burette. Each burette is constructed with a ground glass syringe and chemically resistant PTFE plunger.

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.

Interface and Display Interactive Colour Display

A large, colour LCD screen clearly shows the chosen titration method along with results, units, titration volume, temperature, and mV or pH values.

Detailed Titration Graphs

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 optimisation.

Connectivity and Functionality

Multifunctional Versatility

HI-930 functions as a titrator, pH meter, and mV/ORP meter. Valuable laboratory bench space is saved, and multiple analyses can be performed on one sample.

Rear Connections

HI-930 offers support for one analogue board to allow a pH or ORP electrode, plus one burette to be connected.

Data

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 a LIMS friendly format.

Flexible GLP Management

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

Data Storage

Up to 50 titration and pH/mV reports. Transfer data via USB.

Enhanced Security Options

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

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, plus interior trays safeguard internal electronics.

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.

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 for access to smaller volume titrations without hassle.

Use electrodes with different diameters when needed by simply changing the electrode guide.

No need to move electrodes around, get the best tube alignment for your titration with a rotating holder.

For a more compact design, the electrode holder is mounted directly onto the titrator body. The press-to-release button makes for simple height control.
