Sensor / Probe System
with wash

A sensor/probe system is a complete solution  with an integrated controller, power supply, flow cell, & cleaning unit 

The Photonic Measurements UV254 Display Monitor allows real-time measurements of UV254 and surrogate measurements to be displayed including TOC, COD, and DOC as well as UVT/UVA. This process instrument will output results every twelve second letting you respond to changes almost instantly. 

To calibrate and verify surrogate measurements with a simple guided on-screen process. ​​​​ In applications such as wastewater, the measurement optical component can be kept clean via automated jet-wash cleaning.  This device allows you to measure COD Online.
