Introduction

In today’s fast-paced laboratory environment, accuracy, efficiency, and data integrity are critical for delivering reliable analytical results. While manual titration remains a widely used analytical technique, it often requires significant operator involvement and can introduce variability between measurements.

The HI930 Standard Automatic Potentiometric Titrator from Hanna Instruments is designed to bridge the gap between manual and advanced automated titration systems. It provides laboratories with an intuitive, accurate, and cost-effective solution for automating routine titration workflows without adding unnecessary complexity.

Whether you’re analyzing acids, bases, redox reactions, or performing direct pH and ORP measurements, the HI930 delivers dependable results with minimal operator intervention.

What is an Automatic Potentiometric Titrator?

A potentiometric titrator is an analytical instrument that automatically adds a titrant to a sample while continuously monitoring changes in electrical potential (mV) or pH. The instrument precisely determines the endpoint or equivalence point of a reaction, eliminating subjective visual endpoint detection and improving repeatability.

Automatic titration offers several advantages:

• Improved analytical accuracy
• Enhanced repeatability and consistency
• Reduced human error
• Faster sample processing
• Automatic documentation and reporting
• Better compliance with laboratory quality standards

The HI930 automates these processes while maintaining a user-friendly experience suitable for laboratories transitioning from manual titration methods.

Why Choose the HI930 Automatic Potentiometric Titrator?

1. Simple Automation Without Complexity

Many laboratories hesitate to adopt automated titration due to concerns about complicated software and expensive upgrades. The HI930 addresses these challenges with an intuitive interface and ready-to-use functionality.

Users can begin performing titrations immediately without purchasing additional programming modules or software upgrades. The straightforward menu structure and virtual soft keys simplify navigation, making operation easy even for first-time users.

2. Exceptional Precision with a 40,000-Step Dosing Pump

The accuracy of any titration depends heavily on the precision of titrant delivery.

The HI930 features an advanced 40,000-step piston-driven dosing pump capable of dispensing extremely small and highly accurate titrant volumes. This precise control helps laboratories achieve:

• More accurate endpoint determination
• Improved repeatability
• Reduced reagent consumption
• Greater confidence in analytical results

The system supports burette sizes of 5 mL, 10 mL, 25 mL, and 50 mL, allowing flexibility for different applications.

3. Dynamic Titrant Dosing for Faster Results

One of the standout features of the HI930 is its intelligent dynamic dosing capability.

Rather than dispensing a fixed volume throughout the analysis, the system automatically adjusts titrant additions based on the sample’s mV response.

Benefits include:

• Larger doses during the initial stages of titration
• Smaller, highly precise doses near the endpoint
• Reduced analysis time
• Improved endpoint accuracy

This intelligent dosing strategy enhances both productivity and precision.

4. Multiple Titration Modes for Versatile Applications

The HI930 supports a variety of titration methodologies, making it suitable for numerous laboratory applications.

Supported modes include:

• Fixed pH endpoint titration
• Fixed mV endpoint titration
• pH equivalence point titration
• mV equivalence point titration
• Standardization methods
• Direct pH measurement
• Direct ORP measurement

This versatility allows laboratories to perform multiple analytical procedures using a single instrument.

Compact Design That Maximizes Laboratory Space

Laboratory bench space is often limited, especially in quality control and research facilities.

The HI930 features a compact footprint while integrating:

• Automatic titrator
• Research-grade pH meter
• mV/ORP meter
• Magnetic stirrer

Combining multiple analytical functions into one instrument helps laboratories optimize workspace and increase efficiency.

Intelligent Endpoint Detection

Accurate endpoint detection is essential for obtaining reliable titration results.

The HI930 offers advanced equivalence point detection using first and second derivative calculations. This capability is especially useful in applications where fixed endpoints are not defined by standard methods.

The instrument automatically identifies the point at which the change in mV response is greatest relative to titrant volume, ensuring highly reliable results.

Enhanced Data Management and Regulatory Compliance

Modern laboratories require traceable records and secure data management.

The HI930 supports:

Flexible Data Storage
