The Z-Gard DS Sensor is designed to detect the presence of carbon monoxide and nitrogen dioxide gases in parking garages, vehicle storage areas or wherever else these two toxic gases could be found.

These sensors employ electrochemical sensors which generate a representative output signal proportional to the calibrated operating range. All Z-Gard DS Sensors are available with 2 output versions, a 4-20mA analog output, or an addressable RS-485 digital signal. Z-Gard Sensors with RS-485 digital output are specifically designed to operate as a system with any Z-Gard CXII or C 485 Controller. Z-Gard Sensors with 4-20mA can be installed as stand-alone sensors typically integrated with the Z-Gard C Controller, or common commercial equipment including PLC, DCS, or building automation systems.
