The modern way of data collection for biogas plants






An ongoing and soon evaluation of plant productivity builds for you, as an operator, the base to a trouble-free and efficient business.

Nowadays, an appropriate lab analysis of your samples can just be conducted by a professional analysis laboratory.

With atres OptiMIRS the samples can be examined on site within a few minutes. The liquid manure sample will be spread over the measuring crystal and immediately analyzed.

After the conclusion of measurements, the results are available to the relevant parameters (fatty acids, ammoniacal nitrogen etc.). The results will be released as a trend for a long-term observation of processes.

Advantages of atres OptiMIRS:

  • Rapid analysis results  on site
  • Immediate availability of data
  • Robust measurement tool
  • Easy instruction
  • Low-maintenance (over 5000 h measuring time)
  • No transmittal of samples to analysis laboratory necessary

How it works:

  1. Put a few millimeters of material to be examined on the clean measuring crystal. The measuring crystal ensures the measured mid infrared spectrums to be representative with its large measuring surface.
  2. With the usage of the Start-Button, infrared rays will be transferred through the measuring crystal. The spectrum of the infrared source will be characteristically changed through this sampling.
  3. After 90 seconds is the measurement completed and the user get informed by an acoustic signal. The results of the current measurement show up in the delivered Tablet-PC and can be exported comfortably.
  4. Biogas plants and points of withdrawal can use the installed software for illustrating all measuring results as trends. Therewith, they have always an eye on the development.
