The Crowcon RGD90 is an oxygen detector used within a vessel’s gas detection installation, measuring oxygen concentration over a 0-25% range. Its role is to provide a continuous oxygen reading at its installed point so the alarm equipment can act on abnormal oxygen levels in the monitored space. Input parameters are given as Umax 30 V, Imax 0.16 A and Wmax 0.66 W, with an equivalent capacitance of 0.038 µF, and the detector carries BASEEFA certificate EX 90C2356. This detector is supplied in Used condition.
