GD-K8A Detector Head

The GD-K8A sensor head is a diffusion style head that is ideally suited to meet your gas detection needs. You can choose from one of twenty one sensors to install in this model. These sensors cover a wide variety of applications. The complete sensor housing is only one and a half inches thick, so it can be installed in those tight space requirements. Its easy to install and the hinged housing makes it easy to maintain. The sensor requires only two wires to operate and is quick responding to gas concentrations. It can also be installed to any RKI controller. A battery is built into the housing to ensure that the sensor operates in the event that power failures occur. This eliminates any sensor warm up and down time.
