HM-D2 Automatic Potentiometric Titrator with Conductivity Detection

Product Introduction

The HM-D2 Automatic Potentiometric Titrator builds on the proven four-method titration platform and adds a high-stability conductivity detection module. This expanded configuration enables the instrument to handle not only standard acid-base, redox, precipitation, and complexometric titrations, but also conductometric titration — a critical capability for analyzing weak acid-base systems where traditional potentiometric endpoints are difficult to detect.

The conductivity module measures across a broad range of 0.00 μS/cm to 2,000 mS/cm with ±1.0% FS accuracy, capturing the conductivity inflection point as ion species and concentrations change during titration. This makes the HM-D2 particularly effective for very weak acid or base titrations, mixed-system analysis, and applications in water treatment and pharmaceutical quality control.

Like all models in the series, the HM-D2 features an Android 10 operating system with 7-inch capacitive touchscreen, dual titration modes, 100,000-record storage, and comprehensive data integrity functions including three-level permission management and full audit trail.

Applications

• Weak Acid-Base Titration: Endpoint detection for very weak acids and bases where potentiometric signals are insufficient

• Water Quality Analysis: Conductivity-based monitoring of ion concentration changes in environmental water samples

• Food Safety: Acid value and peroxide value in edible oils; amino acid nitrogen determination in condiments

• Pharmaceutical QC: Raw material assay, pH and conductivity monitoring, and cleaning validation

• Chemical Research: Mixed-system titration analysis requiring dual detection methods

Features

1. Five Titration Methods: Four core methods plus conductivity titration — covering a wider range of analytical scenarios than basic models.
