The integrated system efficiently produces both pure water and ultrapure (UP) water from tap water.

Advanced Controller: The system utilizes a cutting-edge 32-bit microprocessor, ensuring high operational speed and low power consumption. Designed with advanced EMC technology, it boasts strong interference immunity, minimal noise, robust surge resistance, and reliable, stable, long-term operation.

Washing and Circulation Functions: Features both automatic and manual washing and circulation to prolong the service life of the American Dow RO membrane, minimizing bacterial contamination.
Conductivity Meter: Equipped with a resistance constant of 0.01 cm^-1 and a temperature sensitivity of ±0.1°C, it offers automatic temperature compensation.

Intelligent Control System: Fully intelligent control supports multiple users, independent evaluation, and secondary factory and user password protection. System settings are password-protected to prevent unauthorized changes.

Online Diagnosis: Capable of online malfunction diagnosis (for source water, pre-pure water, and UP water), it offers warnings or automatic shutdown and clear indications.
Water Storage: Water can be stored in both a pressure barrel and a water tank, with the system displaying the stored water volume to meet various user needs.

Safety and Design: The main power supply is 24VDC (low voltage) for safety compliance. The ABS engineering plastic housing and water-power separated structure make it suitable for humid environments, protect users from harm, and reduce radiation. The pure water pipe and joint have NSF certification.
Terminal Treatment Options: Various terminal treaters can be selected according to operational requirements, effectively removing contaminants such as endotoxins, nucleases, ultratrace organics, endocrine disruptors (EDS), and VOCs, meeting diverse experimental needs.

User Interface: Features a 7.0-inch color capacitive touchscreen with an animated menu, switchable between Chinese and English. The user-friendly system includes an IR remote control, one-key ON/OFF, one-key pure water and UP water intake, and one-key circulation and washing.

Water Intake: Supports qualitative and quantitative water intake at fixed times, system time settings (Y/M/D/Hr/Min), timed standby (0-60min), and timed shutdown (0-24h).
Data Management: Real-time data monitoring with online inquiry capabilities. A USB host interface allows exporting historical alarm and water intake records.
