Preparing the Oxygen Cell
To prepare the oxygen cell for operation, you must fill it with the electrolyte that was supplied in a plastic bottle.
WARNING! The electrolyte contains potassium hydroxide that is harmful if it comes in contact with
eyes or skin. Consult your company safety personnel for proper procedures for handling the
electrolyte.
1. Unscrew the top cover on the oxygen cell reservoir.
2. Slowly add the entire contents of the electrolyte bottle, approximately three ounces (90 ml), making sure not to
spill any on the outside of the cell. Be especially careful that the electrolyte does not come in contact with any
of the cell electrical connections.
3. Using the min/max window on the oxygen cell, check the electrolyte level. The electrolyte should cover about
60% of the window (see Figure 7 on page 12). The cell is now ready to be connected to the gas line.
4.
Replace the top cover on the oxygen cell.
Note: After you add the electrolyte,
minimum level, refer to "Delta F Oxygen Cell Electrolyte" on page 85 to replenish the cell.
5. Calibrate the oxygen cell as described in "Calibrating the Delta F Oxygen Cell" on page 87. After you
calibrate the oxygen cell, connect it to the gas line as described in the following section.

Connecting the Oxygen Sample System to the Gas Line
To connect the oxygen sample system to the process line, attach a 1/8 inch O. D. (outside diameter) tube to the 1/8 inch
sample gas inlet fitting, using a Swagelok
tubings or fittings which are included in the inlet gas lines.
CAUTION! Do not connect the oxygen cell outlet to flow restricting devices, pressure lines, or
vacuum lines. Pressure differentials across the oxygen cell sensor in excess of 1 psig could be
harmful or damage the cell.
If the gas being monitored does not create a safety hazard, vent it to atmosphere at the sample system outlet. If venting
the gas to atmosphere causes a safety hazard, vent the gas to a safe location. Make sure the venting system does not
create a back pressure on the oxygen cell.
Note: The vented sample will not be corrosive if you install and operate the cell properly.
