The GD-K71D 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-K71D sensors are designed to provide a longer time period between calibrations. Calibration intervals have been extended 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 off site. This eliminates the inconvenience of having calibration gases in the fab or monitoring location. GD-K71D easily connects to an existing PLC system and is ideal for applications needing a local readout or where a relay control is needed. The automatic zero correction software provides excellent long term stability and minimizes false alarms due to zero drift.

Features:

  • LED digital display
  • Sensor information and calibration is stored within sensor memory
  • Several data transmission options available
  • Zero suppression and correction
  • Housing design for narrow wall mounting locations
  • Self-diagnostic functions by microprocessor
  • Electrochemical sensors for most semiconductor gases
  • Built-in sampling pump
  • Easy replacement of pump and sensor
  • Two alarm levels with relays, plus trouble alarm
  • 24VDC operation
  • Optional NEMA 4X housing available

Applications:

  • Semiconductor
  • Chemical Processing
  • Laboratory
  • Manufacturing
  • HVAC

*Please note we can only ship RKI products to customers within the United States
