Accurate chemical analysis is fundamental to scientific research, product development, and quality assurance. Laboratories across industries depend on precise analytical methods to determine the composition, concentration, and quality of samples. Among these methods, titration remains one of the most widely used techniques for measuring the concentration of specific substances in liquids and solutions.
For many years, titration was performed manually using burettes and chemical indicators. While effective, manual titration relies heavily on operator skill and experience. Variations in reagent dispensing, endpoint detection, and result interpretation can introduce inconsistencies that affect analytical accuracy.
As laboratories process larger sample volumes and work under stricter quality standards, automation has become increasingly important. Automatic titration systems streamline the analytical process by precisely controlling reagent delivery, detecting reaction endpoints electronically, and automatically calculating results. This not only improves measurement accuracy but also enhances laboratory efficiency and data reliability.

HIRANUMA automatic titrators improve laboratory efficiency by automating reagent dispensing, endpoint detection, and result calculation for routine chemical analysis.
What Is Automatic Titration?
Automatic titration is an analytical technique used to determine the concentration of a substance by automatically adding a titrant until a chemical reaction reaches its endpoint. Unlike manual titration, which depends on visual observation of color changes, automatic titrators use highly sensitive electrodes and sensors to detect the endpoint accurately.
The instrument continuously monitors changes in pH, electrical potential, conductivity, or moisture content depending on the analysis being performed. Once the endpoint is reached, the system automatically stops reagent addition, performs the required calculations, and stores the analytical results.
Because the entire process is automated, laboratories benefit from greater consistency while minimizing operator-dependent variations.
How HIRANUMA Titration Systems Support Modern Laboratories
HIRANUMA has developed analytical instruments for laboratories for decades, offering automatic titration systems designed to improve productivity while maintaining high analytical accuracy.
The COM-A19 Automatic Titrator provides intuitive operation with automated endpoint detection and data management, making it suitable for routine chemical analysis.
For laboratories requiring greater flexibility, the COM-28 and COM-28S Automatic Titrators support advanced titration methods and expanded analytical capabilities.
HIRANUMA also offers specialized Karl Fischer titrators, including the MOIVO-A19, MOICO-A19, and AQ-300, which accurately determine moisture content in pharmaceuticals, chemicals, petroleum products, food, and other materials. Moisture determination is particularly important because even trace amounts of water can affect product stability, chemical reactions, and manufacturing quality.
By combining automation, precision sensors, and user-friendly software, HIRANUMA titration systems help laboratories improve workflow efficiency while maintaining reliable analytical performance.
