The OMD-625 is typically shipped with a TO2-133 or TO2-233 PPM Oxygen Sensor. The TO2-133 is de-
signed with a base electrolyte for maximum performance in gases such as measuring oxygen in nitrogen,
argon or hydrogen. The TO2-233 is designed with an acid electrolyte and is configured for maximum
performance while measuring oxygen in CO2 and natural gas.
The TO2-133 and TO2-233 have different outputs, so it is important to setup the oxygen analyzer for the
specific oxygen sensor. This can be done with a quick selection in the user friendly MENU. This option
can be found as follows: MENU --> SYSTEM --> SENSOR TYPE --> TO2-133 or TO2-233 --> ENTER
This configuration is normally completed at the factory, but is available to the user should they decide to
switch sensors in the field.
CAUTION: Do not open the oxygen sensor packaging at this time. It is packed in a Nitrogen
purged bag and will be damaged if left exposed to ambient air for a prolonged period of time. It is
recommended that you read through the instruction manual installation and operation sections before
attempting to open the bag the oxygen sensor is packed in. For questions, please contact the factory. If
you are not sure which sensor you have, look at the outside packaging and it will be labelled.
