  • Preventing False Alarms in Ammonia Gas Detection Systems

    For instance, if your goal is to detect 25 ppm of ammonia, choose a detector with a range no higher than 0-250 ppm. Trying to detect 25 ppm with a high range, 0-20,000 ppm detector will tend to cause a false alarm. The lowest alarm set point for a 0-20,0000 ppm detector would be 2,000 ppm (10% of full-scale).
