HI-932-C2-02 Automatic Potentiometric Titration Systems (pH/mV/ISE)

New Compact Design

Price on Application

The HI-932 automatic titrator is designed to perform a wide variety of potentiometric titrations with high accuracy and flexibility, allowing the user to obtain both accurate results and high-speed analysis.

The titrator can perform fixed endpoint or equivalence point titrations and direct measurements by measuring the pH/mV and temperature of the sample.

Reports and materials can be transferred to a PC via a USB interface, saved to a USB storage device or printed directly from the titrator. An external keyboard can also be attached for added convenience.

The HI-921 & HI-922 Autosamplers can be connected for sample automation.

    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.

    Multiple equivalence point detection

    HI-932 can detect multiple equivalence points during one titration as specified and required in certain standard methods and applications.





    Method sequencing

    The HI-932 offers users the option of linking two methods. This allows for two analyses to be run on the same sample including direct measurements, single endpoint titrations, multiple equivalence point titrations, and back titrations.

    Multiple titration types

    Paired with the right electrode from our sensor line, our potentiometric titrators can perform acid/base, redox (ORP), complexometric, precipitation, non-aqueous, argentometric, and ion selective titrations, as well as back titrations and titre determinations.

    Direct measurement functionality

    The HI-932 performs as a high accuracy pH, ORP, and ion selective meter that can link, log, and report direct measurements. Users can easily track and manage data without the hassle of manual record keeping.

    Burettes and dosing system

    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

    The HI-932 comes supplied with a 25mL burette but may be equipped with a 5mL, 10mL or 50mL 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.

    Automatic reagent addition

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

    Methods of analysis

    Customisable methods

    These titrators can store up to 100 user-defined or standard titration and direct measurement methods. Each method may be modified and optimised for performance based on application and user requirements.

    Titration method support

    Onsite installation, training, and customisation is available from one of our product specialists. Hanna offers continued support for any questions you might have along the way.

    Market specific methods packs

    Hanna offers titration method packages for various markets including food, beverage, dairy, wine, and more.




    Data Storage

    Up to 100 titration and pH/mV/ISE reports. Transfer data via USB

    .

    Flexible GLP management

    All necessary GLP (Good Laboratory Practice) information can be recorded with each sample.

    Connectivity and functionality

    Multifunctional

    The titrators also function as a titrator, pH meter, mV/ORP meter, and ISE meter. Valuable laboratory bench space is saved, and multiple analyses can be performed on one sample.

    Multiple Connections

    The HI-932 offers support for two analog boards, allowing up to two electrodes, two burettes, and two stirrers to be connected to one unit simultaneously.

    Autosampler connectivity

    The HI-932 works seamlessly with the HI-922 autosampler featuring 16 or 18 sample tray options, automatic tray identification, and automatic beaker detection. Up to three peristaltic pumps for reagent addition and removal can be connected and real-time analysis and sequencing progress is visible on the HI-932 display as well as indicated by the LED lights of the autosampler.

    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.

    Fully customisable titration methods

    Titration graphs

    Titration graphs can be viewed on-screen or saved as images and transferred along with titration report.

    Customisable reports

    Data to be stored in titration reports is fully customisable.
