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 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 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.
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.
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.
The HI-931 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.
With Hanna’s Clip-Lock™ burette feature, it only takes a few seconds to exchange titrants and reagents preventing cross-contamination and saving time.
The HI-931 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.
Our unmatched 40,000 step piston driven pump is capable of dosing extremely small and highly accurate volumes of titrant or reagent.
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.
Spring-loaded actuator allows you to quickly raise or lower the stirrer/electrodes with the push of a button
Add reagents to your samples automatically before every titration using integrated peristaltic pumps
The burette well is sealed on the bottom to catch drips and spills
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.
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.
Hanna offers titration method packages for various markets including food, beverage, dairy, wine, and more.
Up to 100 titration and pH/mV/ISE reports. Transfer data via USB.
All necessary GLP (Good Laboratory Practice) information can be recorded with each sample.
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.
The HI-931 offers support for one analog board to allow an electrode, up to two burettes, and a stirrer to be connected to one unit simultaneously.
A large, colour LCD screen clearly shows the chosen titration method along with results, units, titration volume, temperature, and mV or pH values.
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.
Titration graphs can be viewed on-screen or saved as images and transferred along with titration report.
Data to be stored in titration reports is fully customisable.
