HI932 Automatic Potentiometric Titration System
The HI932 is an automatic potentiometric titration system designed for pH, mV, and ISE measurements. This compact system features a redesigned electrode holder, integrated peristaltic pumps, and support for multiple titration types. The HI932 combines advanced titration capabilities with direct measurement functionality for versatile laboratory applications.
Key Features
Compact and Improved Design
- Takes up half the lab space compared to the HI900 family
- Redesigned electrode holder with spring-loaded actuator for quick height adjustment
- Space-saving geometry allows for sample sizes less than 50 mL
- Support rods mount directly to the titrator — no need for special mounting hardware
- Integrated peristaltic pumps add reagents automatically before every titration
- Sealed burette well on the bottom to catch drips and spills
Titrator Capabilities
- Dynamic titrant dosing relates titrant volume to mV response for timely and accurate results
- Equivalence endpoint detection identifies greatest mV response relative to titrant volume
- Signal stability timing monitors mV response stabilization before next dose
- Multiple equivalence point detection during one titration
- Method sequencing allows linking of two methods for multiple analyses on same sample
- Direct measurement functionality as high accuracy pH, ORP, and ion selective meter
Supported Titration Types
- Acid/base
- Redox (ORP)
- Complexometric
- Precipitation
- Non-aqueous
