fittings are preferred throughout the installation.
8. Connect the calibration chamber to the MG-101 outlet fitting, using 1/4” OD SS tubing. Then, leak test the
connection.
Note: GE Sensing Sample Cell #2830 is the preferred calibration chamber for M2 Type probes
9. At the outlet of the calibration chamber, connect at least 5 ft (1.5 m) of 1/4” OD tubing as a vent to atmosphere.
The tubing may be coiled to save space.
10. Insert the sensor to be calibrated into the calibration chamber and tighten it sufficiently to ensure a leak-proof seal,
but be careful not to over-tighten the sensor.
