UV water quality monitor Q46

opticalturbidityDOC

The Q46UV Monitor continuously monitors the quality of raw water, treated water, recycled water, or wastewater effluents. With a relatively long 20mm absorption path length, this sensor provides excellent sensitivity to small changes in Dissolved Organic Carbon (DOC). Employing a pulsed UV LED light source and scratch-resistant sapphire optical windows, the UV-254 sensor will provide years of trouble-free monitoring. UV Absorption and Turbidity in a Single Sensor UV-254 measurements are a practical indicator of dissolved organic compounds in water. Traditional UV-254 measurements are a practical indicator of dissolved organic compounds in water. Using a UVA sensor allows for long-term, continuous monitoring of organics without the need for chemicals and reagents. The sensor has the advantage of being near real-time, providing input to treatment control systems and alarming of abnormal conditions. Routine maintenance consists of cleaning the optical surfaces, which is generally simple and quick. The Q46UV sensor provides additional optical measurements for added measurement capabilities and increased reliability. Infrared sensors for measuring both 90° Scatter Turbidity and IR absorption are built into the UVA sensor. These additional optics allow for the measurement of both UV-254 and Turbidity, a unique capability to enhances the usefulness of the monitoring package, especially in raw water monitoring applications. The IR absorption measurement is used to correct measurements for minor optical fouling that can occur over weeks or months of operation. Sensors in contact with raw or settled water samples may experience fouling from iron and manganese.
