5.6 Sensor Replacement

While it is possible to replace a sensor in the field, TAI
recommends that the analyzer be shipped back to the factory for sensor
replacement and requalification. If the sensor is replaced in the field, the
customer must contact TAI Customer Service to obtain the required
input data to linearize the new sensor.
