A high-performance titrator made simple.

Focus on your most essential titrations and get high-quality results with our HI901C automatic titrator.

Get the most out of one device.

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.

Each titrator can store up to 100 customizable methods of analysis to accommodate any of your different samples or procedures.

If lab space is scarce, our titrator doubles as a benchtop meter for direct pH, redox, and ion selective measurements.

Titrator Dosing System

Change reagents without worry.

Our exchangeable Clip Lock™ burette system helps you conveniently separate and switch between your reagents so you don’t have to be concerned about cross-contamination.

Be confident in your results.

Our unmatched 40,000 step piston driven dosing pump is capable of dosing extremely small and highly accurate volumes of reagent, helping you achieve a very precise endpoint.

Precision is key.

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.

Titrator Display & Navigation

All of your important information is displayed.

Our large color display shows you everything you need to know during testing.

Track your progress in real-time.

Our live titration curve helps you quickly recognize patterns and problems that may arise during your analysis.

Explore titrator menus with ease.

Custom keys allow you to clearly navigate between screens so you don’t get lost.

Titrator Data & Reporting

Highlight your most important information.

Final reports are customizable so you can make sure you are viewing and storing your most important information.

Safeguard the integrity of your data.

Our software allows you to record full GLP (Good Laboratory Practice) data so there is no need to compromise the quality of your results.

Move your information easily across devices.

Use our software or a USB to conveniently transfer files between your titrator and computer.

Titrator Connectivity

View and print reports easily.

You can print reports directly from the titrator with a connected printer and conveniently view results with a connected monitor.

Take advantage of the versatility.

Connect the devices that help you most, whether it be an analytical balance for automatic sample entry or a printer for your reports.
