Continuous measurement of nitrogen oxides (NOx)

As the system generates large amounts of data over time, it can be a time consuming task to do NOx reporting when the reporting becomes continuous. Save yourself for a lot of trouble with the right reporting system.

Continuous measurements often means storing data every 10 seconds around the clock every day all 365 days a year. This is why the yearly  emissions report can turn out to be a large calculation to handle. Let ReportLoq do the work for you and monitor progress all year round using the internet-based access to your system.

We offer a solution which can be tailor made to fit your exact needs. This is some of the current options:

  • Limit values – ReportLoq can, if you need to stay below a certain limit value, document your emissions in an easy readable format

  • Unmanned plants – ReportLoq can in addition to the three main versions Core Pro and Enterprise be delivered in a “Lite” version without real time monitoring. This is well suited for unmanned plants

  • Tax reports – ReportLoq summarises your emissions in emitted kilos per day letting you easily settle NOtaxes

  • Normalisation and QAL – ReportLoq automatically normalises your measurements to reference conditions taking QAL2 and QAL3 into account

  • Web access – ReportLoq+ Pure Cloud is designed with remote access to measured data using This provides you with easy access your emissions where ever you are

  • Entry of QAL2 as a/b values or mA

  • Entry of QAL3 values after analyzer validation with calibration gasses

  • Calculation of QAL3 using the CUSUM method according to EN 14181

  • Automatic appliance of QAL2+QAL3 values in aggregated values

  • Entry of QAL2 calibration interval with sub-sequential check for compliance of the AMS validity accordingly to EN 14181:2014 (E) 6.5

  • Completion of QAL reports

The placement of the measuring point and normal wear and tear are taken into account when using the QAL functions.
