GG-O2
Maintenance
The GG-O2-C was designed for long life and minimal
maintenance. For proper operation it is essential
that the test and calibration schedule be adhered to.
Calibration Technologies recommends the following
maintenance schedule:
Maintenance Guidelines:
• The sensor is shipped with a factory calibration.
Sensor should be calibrated 6 months from
purchase date.
• Calibrate the detector at least once every 6 months.
•
Calibration should be performed with certified
calibration gas. Calibration kits and replacement
cylinders are available from Calibration
Technologies.
• All tests and calibrations must be logged.
• Always disconnect power at the controller before
performing any wiring at the sensor.
Sensor Life:
These electrochemical cells are long-
life sensors, but several things can cause the cell
chemicals to become depleted including:
• a period of time
• exposure to high temperatures
Typical sensor life in 20.9% oxygen is three years.
When the cell becomes depleted, a replacement cell
can be obtained from Calibration Technologies. Simply
unplug the cell’s ribbon cable from the transmitter,
pull the old cell from the spring clip, discard the old
cell and replace it with a new cell. The sensor can be
calibrated once the resting signal stabilizes, typically
within a one hour warm-up period. Part number for
replacement cell:
GG-O2-C-RC.
