Photonic Measurement | UV254 Probe
Process and Industrial Instrument for surrogate measurements of TOC,DOC,COD,BOD etc
The UV254 probe continuously measures water in real time. This can be done by either taking a side stream to a flow cell, or by fitting it to a T-piece inline, or immersing it in an open channel.
For applications such as waste water, the measurement optical component is kept clean via jet-wash cleaning. The probe can be configured to be made from either stainless steel, aluminium or titanium.
The Photonic Measurements UV254 Display Monitor allows real time measurements of UV254 and surrogate measurements to be displayed and trended over time. The daylight readable touchscreen makes navigation of menus intuitive. Display a number of surrogate measurements such as TOC, COD and DOC as well UVT and UVA. Calibrate and verify surrogate measurements with a simple guided screen process.
