Product Overview: RAEGuard S Fixed Gas Detector in a Stainless Steel Housing
RAEGuard S
The RAEGuard S is a permanently installed gas detector for hydrocarbon combustible gases, carbon dioxide and a wide range of toxic gases. It is a flexible detector which provides both an analog (4-20mA) and digital (RS-485, ModBus RTU) output signal. The RAEGuard S uses a smart sensor which can be off-line pre-calibrated. An explosion-proof stainless steel enclosure and magnetic key non-intrusive operation make the RAEGuard S ideal for use in hazardous environments. The RAEGuard S is equipped with a local digital display and LEDs for viewing of gas concentration and alarm conditions
