UV300 Online Water Analyzer

The UV300 is an economical online water analyzer designed to monitor one or two specific parameters. Utilizing reliable UV-visible spectroscopic technology, it measures organic matter, nitrate, color, and PAH. It can also be equipped with an optional colorimetric module for parameters such as PO₄, Cl₂, NO₂, Fe, and Al, along with a laser-diode turbidity sensor.

Additionally, it supports external probes for pH, ORP, dissolved oxygen, and conductivity measurements. The system features an automatic acid-cleaning mechanism and a durable xenon lamp to ensure minimal maintenance requirements. A web-based interface allows for easy remote operation and troubleshooting, enhancing overall usability and efficiency.
