Reliability to support regulations

Measurement reliability supports regulatory compliance requirements Security functionality for supporting data management

The UV oxidation-conductivity method enables highly sensitive measurements with a simple analyzer design.
The system achieves high sensitivity with a detection limit of 0.1 µg/L, which is suitable for ultra-pure water quality control. User authentication and access rights control
It is also compliant with the pharmacopoeia requirements of various countries, such as the USP and EP.
Users can be authenticated based on an ID and password.
User access rights are controlled according to four user levels: “Administrator”, “Main
User”, “User”, or “Guest”.
