ART GUIDE
INTRODUCTION
The HI931 automatic titrator is designed to perform a wide variety of potentiometric titrations with high accuracy, flexibility and
reproducibility, allowing the user to obtain both accurate results and high-speed analysis.
The titrator can perform fixed endpoint or equivalence point titrations and direct measurements by measuring the pH/mV and
temperature of the sample.
Reports and methods can be transferred to a PC via a USB interface, saved to a USB storage device or printed directly from the
titrator. An external keyboard can also be attached for added convenience.
How can I find certain information?
- The Quick Start Guide will help the user learn how to operate the titrator within a short period of time.
- The Instruction Manual provides a complete description of the operating principles (user interface, general options, methods,
titration, pH, mV and ISE mode, maintenance, etc.).
- The Titration Theory outlines the basic concepts of titration.
- The contextual Help screens contain detailed explanations of every screen.
SAFETY MEASURES
The following safety measures must be followed:
1. Never connect or disconnect the pump assembly or other peripheral with the titrator turned on.
2. Verify that the burette and the attached tubing are assembled correctly.
3. Always check that the titrant bottle and the titration beaker are placed on a flat, stable surface.
4. Always wipe up spills and splashes immediately.
5. Avoid the following environmental working conditions:
• Severe vibrations
• Direct sunlight
• Atmospheric relative humidity above 95% non-condensing
• Environment temperatures below 10°C and above 40°C
• Explosion hazards
6. Have the titrator serviced by qualified service personnel only.
