Modular sensor design

Analyse up to 4 different gases plus pressure and humidity simultaneously

In order to adapt gas analysis as flexibly as possible to individual measurement tasks, the single components were designed modularly. This resulted in a »modular system« in which the various photometric components such as detectors, emitters, measuring sample cell, etc. can be assembled user-specifically.

With this sophisticated sensor design, customer-specific applications can be realized without needing a completely new development. The modularity makes replacement and maintenance considerably easier when servicing is required. In contrast to this design, common completely glued gas sensors can only be replaced as a complete unit thus generating high follow-up costs (total cost of ownership) in case of maintenance.

Optionally, modules can also be equipped with a sensor for oxygen, pressure and humidity.
