Superior design for the busy lab.

The Cycoloy® body is durable, heat-resistant, and resists staining. Dedicated menu buttons are part of the control panel making it fully sealed and easy to clean. A high contrast LCD display makes every character on the display stand out and the wide viewing angle allows measurements to be seen from any angle. The backlight is adjustable for your viewing preference and with a backlight saver option protects the display during periods of inactivity.

Maximize your workspace.

This new generation of titrator features a 50% smaller footprint than the HI901 Automatic Titrator for maximum use of your benchtop lab space.

Intuitive User Interface

Functional keys on the control panel that correspond to virtual keys on the display allow for simple and quick navigation between screens and menu. If you need additional information about a screen, simply press the dedicated button for help.
