Applications
The SEC IREvolution™ ammonia detectors are designed to be used as an upgrade in the same
applications where electrochemical sensors have been applied.
- Refrigeration
- Power generation
- Compressors
Operation / Description
SEC IREvolution™ is a complete self contained optical ammonia gas detector. The sensing and
reference elements are self-compensating for optical integrity and other signal inhibitors. The
industry standard 4 - 20 mA analog output provides remote alarm, fault and calibration signals.
