6.3. Oxygen Sensor Option

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 50C.

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

Valves option.
