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.

IAQ 9455 CO2 Monitor
Using advanced non dispersive infra red technology the IAQ 9455 provides fast accurate monitoring of CO2. The sensor is solid state, requires no service and remains stable and accurate for up to one year with no need for re-calibration. Response time is just a few seconds and a visual display on the front panel indicates current CO2 levels. Outputs available are voltage (0-10V) current (4-20mA) and an Ethernet digital output via an RJ45 connector. Power requirement is 10-32V DC and power consumption is only 0.25 watts. The sensor is not affected by water vapour or temperature making it ideal for use in a wide variety of applications. The sensor can be field tested with CO2 gas at anytime to confirm proper operation. The IAQ 9455 is competitively priced and quantity discounts are available on request.
Typical Applications Include...
HVAC, LEV, School Classroom Monitoring, Cellar Monitoring, Incubators, Office Atmosphere Optimisation, Hospitals, Confined Space Monitoring, In Vehicle Monitoring, Car Parks and Garages . etc.
The RAEGuard EC is a permanently mounted (fixed) toxic gas or oxygen sensor/transmitter that operates from a 9 to 36 VDC power source and provides an analog (4 to 20mA) and digital (RS-485) signal output. Housed in an explosion-proof enclosure, the RAEGuard EC is equipped with a local digital display of the gas concentration and function keys for performing calibration. The RAEGuard EC is operated with a standard 4 to 20mA/RS-485 controller or as a stand-alone sensor module. Gases available are CO, H2S, SO2 and Oxygen.
