Sensor technology supplier Royal Eijkelkamp launched a versatile spectral analyser to measure biochemical oxygen demand (BOD), chemical oxygen demand (COD) and total organic carbon (TOC) at a waste water treatment plant.

The in situ analyser operates within the wavelength range 200 to 710 nm (UV/Vis) and is able determine various parameters in waste water simultaneously.

Entire wavelength
The result of a single measurement is an absorption spectrum over the entire wavelength range.
The Eijkelkamp spectrometer features an adjustable measuring path length, by which no water becomes too dirty for measurement.

In contrast to electrochemical sensors and multi-parameter measurements, a spectrometer is a very versatile instrument.

High temperature range
The measuring head of the Eijkelkamp spectrometer is made of V4A stainless steel and includes only the optics and the compressed air cleaning system.

The control and evaluation electronics are installed in the associated sensor module. As a result, the spectrometer can be used in a high temperature range (up to 110°C).

This makes it suitable for use in the medicine or food industry, as the measuring head can be sterilised at high temperatures.

Real time
Parameters in waste water treatment plants that are observed continuously and in real time, make it possible to notice changes in concentrations and to react at once.

Furthermore, the integrated automatic compressed air cleaning of the measuring path makes sure that the device can reach a very long operating lifetime and service intervals.

The spectrometer is suited for monitoring in different areas of treatment plants. The measuring head can be installed directly into the flow or basins without the need for ultrafiltration.
