The Model 200AH can be equipped with an optional paramagnetic oxygen sensor that is capable 
of measuring full scale ranges from 5% to 100%.  The option consists of the paramagnetic sensor 
module, an interface electronics board, a flow control orifice that generates a flow of about 
80 cc/min through the sensor, and a temperature controlled oven that maintains the sensor and 
flow control orifice at 50

C.  

Note that an Oxygen Sensor cannot be included in an instrument that also includes the Zero/Span 
Valves option.
