New Light Module for Accurate NOx Measurement

Nov 09 2017 Read 370 Times

increasing sense of environmental awareness around the globe is demanding higher standards for environmental monitoring. Heraeus Noblelight has developed an easy to use, plug & play light solution based on NOx light technology, for very accurate measurement of NOx and other pollution gases.

The NOx electrodeless discharge lamp (EDL) is a lamp with N2, O2 gas fill that emits a spectrum in the wavelength range between 200 nm to 600 nm. NOx-specific spectral lines in the 200 nm region can be used for the detection of NO and NO2, H2S, NH3, SO2 and other pollution gases.

Heraeus Noblelight’s new plug & play light solution for reliable NOx measurement is a lamp module that offers a pre-tuned UV-light source in a stable environment to ensure optimised performance. The NOx lamp module has an integrated EDL and comes with the corresponding power supply combined in a box. This makes integration into an OEM UV-RAS system very easy and cost efficient, plus light source replacement at End Of Life is by simply replacing the module in the field.

High accuracy and stability are required in any measurement process. The new NOx module delivers both and even more. It is easy and effective in use, and without the need for consumables, it ensures very low operating costs. Enabling fast and accurate absorption measurements without cross-interference from water and CO2 , it saves time during the measurement process and makes dynamic (real time) measurements possible with high measurement confidence - a real competitive advantage for UV-RAS compared to other technologies.
