KD-12 Series Explosion-proof (ATEX) Detector

KD-12 Series offers diffusion type detectors integrated with the sensing element and the readout display. They are small, lightweight units that are suited for both indoor and outdoor installations.

Depending on the model chosen, detectors are available for detection of various gas types, i.e. Flammables, Toxic Gas & Oxygen.

The detectors come with both digital and analogue outputs that allow easy interfacing with a central supervisory system for larger applications.
