【Exhibition Information】Exhibiting at JASIS 2025 | Proposing automation and labor-saving solutions for water quality analyzers! Live demonstration with a turntable will also be conducted 【Starting September 3!】

  • Seminar・Event

Toa DKK will exhibit at "JASIS 2025," which will be held at Makuhari Messe from September 3 (Wednesday) to September 5 (Friday), 2025. Our exhibition booth is located in Hall 7, No. 7B-501. At our booth, we plan to showcase a wide range of water quality analysis instruments utilizing our unique electrochemical sensor technology. A highlight will be the automatic measurement system for multiple samples, which connects a tabletop water quality meter and an automatic titrator with a turntable (TTT-710). We will introduce solutions that contribute to the automation and labor-saving of analytical tasks, featuring actual equipment. In addition, you can view a diverse product lineup including the X series (tabletop water quality meters), P40 series (portable water quality meters), ICA-7000 (ion chromatograph), IA-300 (ion analyzer), AUT-801 (automatic titrator), kemio (heavy metal analyzer), DR series (spectrophotometers), and turbidity meter series. During the exhibitor seminars, we will provide technical information on three themes: "Fundamentals of Water Quality Measurement," "Fundamentals of Automatic Titrators," and "Fundamentals of Ion Chromatography (IC)." We sincerely look forward to your visit.
