Automatic total nitrogen/phosphorus monitoring system

TPNA-500

The latest model combines 60 years of water measurement technology to achieve reduced life cycle costs, compliant regulations.

The future of total nitrogen and total phosphorus measurement not only involves compliance with regulations but also has the potential to contribute to proactive enhancements of corporate values. The future of measurement, regulatory compliance, and enhancement of corporate value will be pursued by proposing technological innovation, improvement, and LCC (Life Cycle Cost) reduction.
