The HI931 titrator delivers incredible results and speed for increased productivity. HI931 functions as a titrator, pH meter, mV/ORP meter, and ISE meter. Titrate for a variety of measurements including acids, bases, redox, and selective ions. With no additional programming upgrades to purchase, you can start measuring right away. 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.
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.
This new generation of titrator features a 50% smaller footprint for maximum use of your lab space. The sealed body is precision.engineered to resist spills and dust and a high-contrast display shows you everything you need to know during testing. 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.
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.
Hanna's 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. Add a second analog board, burette, or peristaltic pump 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.
