UV Antifouling
A Crystal IS UVC LED (Ultraviolet 250-300 nm@500µW Light-Emitting Diode) is integrated into the conductivity sensor quartz cell (patent pending). The UVC LED sterilizes the early growth of biofouling, thus eliminating environmental drift in the conductivity sensor.
Conductivity measurement is accomplished by using a unique platinum seven- ring quartz cell. The advantage of this design is that there are no platinum black surfaces which can be contaminated or can deteriorate during profiling or monitoring. The sensor can be easily cleaned in the field.
