Sentek Smoke Detector

The SD119-G series include 2-wire and 4-wire detectors, which provide fast and reliable response for photoelectric smoke and heat (135PoPF) detection. While the smoke and heat detection circuits operate independently, their outputs being "OR' connected, The Sentek’s SD119-G series detectors provide the fire detection performance by acting as a smoke sensor and/or a 135PoPF heat detector at the same location.

Applications: Water quality testing, Environmental research, Process Control Measurements, Food analysis, Biological analysis etc.
