HM-D1 Automatic Potentiometric Titrator

Product Introduction

The HM-D1 Automatic Potentiometric Titrator is a precision analytical instrument designed for laboratories that require reliable, automated titration without the complexity of multi-module configurations. Built on a modular hardware platform, the HM-D1 supports the four fundamental titration methods — acid-base, redox, precipitation, and complexometric titration — covering the majority of routine volumetric analysis tasks.

Powered by an Android 10 operating system with a 7-inch capacitive touchscreen, the instrument offers an intuitive graphical interface that reduces the learning curve for new users. Its high-precision fluid control system achieves titration repeatability of ≤0.2%, ensuring consistent results across repeated runs. The dual titration mode — conventional and specialized — allows users to either customize parameters freely or run pre-configured standard methods with one-click operation.

With 100,000-record local storage, PDF and Excel export, built-in thermal printing, and Wi-Fi connectivity, the HM-D1 integrates seamlessly into modern laboratory workflows. For labs seeking an affordable entry point into automated potentiometric titration, the HM-D1 provides proven performance with straightforward operation.
