RKI Instruments GD-K77D - Manual (Page 6)

1 • Overview Model GD-K77D Operator’s Manual
Overview
The Model GD-K77D has been specially developed for semiconductor gas-leak
monitoring and is one of the most advanced units of its kind. It contains a long-life pump
and electrochemical sensor to detect a wide variety of semiconductor gasses quickly and
reliably. The long-life sensor has a memory so it can be calibrated separately from the
monitor, then installed for quick and easy servicing. The Model GD-K77D’s narrow
footprint and wall mounting bracket permit flexible placement. Built for reliability and ease
of use, the Model GD-K77D includes the latest innovations in gas-leak monitoring
technology:
• Digital LED display for readout of gas concentrations
• Sensor information and calibration stored within sensor memory
• Several transmission options available
• Self-diagnostic functions performed by microcomputer
• Easy replacement of pump and sensor
• Two alarm levels plus trouble alarm
WARNING: The Model GD-K77D detects semiconductor gasses that may be toxic
or combustible. Users of the Model GD-K77D must follow the
instructions and warnings in this manual to assure proper and safe
operation of the Model GD-K77D.
