Installing the Oxygen Sensor

The GPR-3100 is equipped with an integral oxygen sensor that is fully operational from the shipping

container with the oxygen sensor installed, tested and calibrated by the manufacturer prior to shipment.

However, for a variety of reasons it may be necessary to ship the oxygen sensor separately.

Caution: DO NOT open the oxygen sensor. The sensor contains a corrosive liquid electrolyte that could

be harmful if touched or ingested, refer to section 10 Material Safety Data Sheet of this manual.

Avoid contact with any liquid or crystal type powder in or around the sensor or sensor housing, as either

could be a form of electrolyte. Leaking sensors should be disposed of in accordance with local

regulations.

Note: All analyzers must be calibrated once the installation has been completed and periodically

thereafter as described below.

Procedure:

1. Using the 5/16 wrench supplied loosen but do not

remove the clamp bolt – the long one located in the

center under the bottom section of the sensor

housing.

2. Rotate the upper section of the sensor housing 90º

to disengage from the clamp.

3. Remove the upper section by pulling it straight up

and place it on a smooth surface.

4. Open the barrier bag containing the new sensor.

5. Remove the new oxygen sensor from the shipping

bag and remove the red label and the gold ribbon

(shorting device) from the PCB at the rear of the

sensor.

6. Caution: Minimize the time the sensor is exposed to

ambient air.

7. Place the new sensor in the bottom section of the sensor housing with the PCB facing up.

8. Place the upper section of the sensor housing over the sensor.

9. Gently push the upper section downward and rotate 90º to engage the clamp.

10. Finger tighten the clamp bolt and one full turn with the 5/16 wrench to compressed the o-ring seal.
