- IREX is a fast response sinter-free, fully featured infrared gas detector that produces an mV Wheatstone Bridge output as used on conventional pellistor based systems.
- Designed to allow easy upgrading of existing pellistor based fixed point gas detectors.IREX replaces old pellistor heads by simply mounting on the original junction box and connecting to the original cable. The IREX concept enables upgrade to dual-wavelength IR gas detector technology without incurring the very significant costs associated with replacing the control system and re-installation.
