    The GD-K77D is a complete sample drawing gas monitor, including digital
    readout and alarm relays. A new gas sensor technology using an intelligent
    sensor for remote location calibration and setup is used. The new GD-K77D
    sensors are designed to provide a longer time period between calibrations.
    Calibration intervals have been cut in half to12 months of on-line service which
    equates to reduced maintenance cost. In addition, the sensors can be calibrated
    away from the gas detector installation, for example in a service area or offsite.
    This eliminates the inconvenience of having calibration gases in the fab or
    monitoring location. GD-K77D easily connects to an existing PLC system and is
    ideal for applications needing a local readout or where a relay control is needed.
