S-Guard Ir
GasTech Australia Smart Guard series S-GuardTM Series GIR-3000 hydrocarbon detector is a single source dual wavelength instrument. The sensing and reference elements are self-compensating for optical integrity and other signal inhibitors. The industry standard 4 -20 mA analog output provides remote alarm, fault and calibration signals.
