field-serviceField Service Advantages

Thanks to our modular design, routine field service is quick and easy.  Just remove the cover from the dust- and water-tight enclosure by loosening the four captive fasteners, remove the sensor board and install a pre-calibrated replacement.  All mounting fasteners and sensor wiring are left completely undisturbed ensuring immediate, problem-free resumption of normal gas monitoring and control.
