Humidity Effect

Humidity has no effect on the performance of the MAXO2 analyzer other than diluting the gas, as long as there is no condensation. Depending on the humidity, the gas may be diluted by as much as 4%, which proportionally reduces the oxygen concentration from the dry concentration. Environments where condensation may occur are to be avoided since condensate may obstruct passage of gas to the sensing surface, resulting in erroneous readings and slower response time. For this reason avoid usage in environments greater than 95% relative humidity.

3. OPERATION INSTRUCTIONS

To check the oxygen concentration of a sample gas: (after the unit has been calibrated)

1)Connect the sample hose to the barbed fitting on the bottom of the unit.

2)Attach the other end of the sample hose to the sample gas source and initiate flow of the sample to the unit at a rate of 1-5 liters per minute (2 liters per minute is recommended).

3)Using the ON/OFF key, make sure the unit is in the power on mode.

4)Allow the oxygen reading to stabilize. This will normally take about 30 seconds or more.

4. SENSOR REMOVAL AND REPLACEMENT

The OM-25A is shipped with a new MAX-250 oxygen sensor installed. Although the sensor has a very long expected life, eventually the sensor will require replacement. Removing or installing a sensor, when necessary, is a very simple procedure. To remove and install a new sensor:

1)With the front of the analyzer facing downward and the bottom facing away from you, press down with both thumbs on the center of the battery compartment cover and slide the cover off.

2)Remove the white barb fitting by turning the barb counter-clockwise. A 7/16” wrench may be needed to aid in the removal.
