Product Description

UV-254 and Turbidity Measurement in onesensor

Water quality monitoring continues to grow in importance as water sources come under increasing pressure. Conventional measurements of turbidity, pH, conductivity, and color provide useful information but do not reflect changes in dissolved organic constituents. Many of these dissolved organic compounds absorb UV energy. A UV-254 absorption measurement has increasingly become a useful indicator of organic carbon content, providing operators with real-time information oncontaminant levels.

SRV UV254 MONITOR

SRV Model UV 254 continuously monitors the quality of raw water, treated water,recycle water, or wastewater effluents. With a relatively long 20 mm absorption path length, this sensor provides excellent sensitivity to small changes in Dissolved Organic Carbon (DOC). Employing a pulsed UVLED light source and scratch resistant sapphire optical windows, the UV-254 sensor will provide years of trouble-free monitoring. UVABSORPTION & TURBIDITY INA SINGLE SENSOR • Long life PulsedUVLED for extended service life. • 20 mm measurementpath for high sensitivity • 530 nm turbidity measurement(ISO-7027) • IR sensor measuresboth 90° scatter and absorption • Analog outputs for both UVC and Turbidity • Available 3rd output for DOC • User editable tablefor UVA vsDOC/TOC/COD/BOD/TSS • Chemical cleaning systemoption • Automatic Sensor FoulingCompensation

DISSOLVED ORGANICCARBON UV-254 measurements are a practical indicator of dissolved organic compounds in water. Traditional methods such asTOC,COD, and BOD all capture more organics and other potential contaminants but have the drawback of being expensive and maintenanceintensive. In fact,most are done only in the laboratory due to the complexity of on-linesystems. UV-254 measurementis much simpler and can be correlated to DOC levels. It has the advantage of being nearly real time, providing input to treatment control systemsand alarming of abnormal conditions. Routine maintenance consists of cleaning the optical surfaces, which is generally simple andquick. 

UV & TURBIDITYOPTICS The UV254 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.TheIRabsorption measurement is used to correct measurements for minor optical fouling that can occur over weeks or months of operation.

AUTOMATIC SENSOR CLEANING Sensors in contact with raw or settled water samples may experience fouling from iron and manganese. Prechlorination causes iron and manganeseto precipitate out of solution and coat surfaces that are in contact with the sample. While manual sensor cleaning is easy,SRV offersQClean, an automatic sensor cleaning system that reduces user maintenance. The cleaning system consists of an automatic sensor wash system that injectsa cleaning solution into the sensor flow chamber at the frequency programmed by the operator. The cleaning solution contains chemicals that dissolve iron and manganese that has accumulated on optical surfaces.The duration of the cleaning cycle is about 15 minutesbut can be changed by the operator to meet specific applicationrequirements.

FLOWCELLOR SUBMERSIBLE INSTALLATION UV-254 sensors are designed for either submersion or flowcell installation. Flowcells are supplied with a flow regulator installed in the outlet fitting to maintain flow at 450 ml/min.
