The HI932 Advanced Automatic Titrator is the answer to your advanced titration needs. Fully customizable to meet your testing needs, the HI932 delivers accurate results and intuitive user experience, all in a compact package. Titrate for a variety of published methods at the push of a button, as well as perform direct measurements and back titrations for complex samples. For those that require greater automation, pair your HI932 with the HI922 Autosampler for the most accurate results with the least amount of effort.
HI932 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. Connect the devices that help you most, whether it be an analytical balance for automatic weight sample entry or a printer for your reports. You can print reports directly from the titrator with a connected printer.
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.
With an angled electrode holder and removable stirrer, smaller volume titrations are now seamless. Not only can your titrator hold more electrodes and tubes, but it is also easier than ever to reposition your electrode holder using a newly designed press-to-release button and rotating disk. 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.
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
Our unmatched 40,000-step dosing pump is capable of dosing extremely small volumes of titrant to help you achieve a very precise endpoint for greater consistency. There is no other like it. With the second analog board, a burette or peristaltic pump can be added for more power, more usability, and more versatility.
The exchangeable Clip Lock burette system helps you conveniently separate and switch between your reagents - it only takes a few seconds to exchange titrants and reagents preventing cross-contamination and saving time.
A dynamic dosing algorithm allows for timely and accurate titration results by providing larger doses near the beginning of a titration and smaller, more precise doses near the titration endpoint.
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 from our sensor line, this potentiometric titrator can perform any number of standard titrations, back titrations, as well as perform direct pH, ORP, and ion selective readings.
Streamline Your Testing: Reduce downtime and increase efficiency when you perform multiple analyses linked in sequence. A linked method function allows for two analyses to be run on the same sample including direct measurements, fixed endpoint titrations, multiple (up to 5) equivalence point titrations, and back titrations. Track your progress in real-time with onscreen titration curves.
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.
