MULTIPARAMETER WATER QUALITY METER
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.
