AMI Analyzer Manual
Model 2001LC Series Oxygen Analyzer
3
Oxygen sensor:
AMI manufactures its own electrochemical sensor. This measures the concentration of
oxygen in a gas stream, using an oxygen specific chemistry. It generates an output
current in proportion to the amount of oxygen present, and has zero output in the
absence of oxygen, thus avoiding any requirement to zero the analyzer. The cell is linear
throughout its range. The span calibration may be performed using standard span gases
or ambient air. Unlike competitive sensors, the AMI sensor is made using a high capacity
metallic body that provides long life with about twice the active ingredients of
conventional sensors, but with much faster come-down times – typically under twenty
minutes to 10ppm from a 1 minute air exposure.
Sensor Warranty:
The sensor is warranted to operate for a period determined by its class. If the sensor
ceases to operate correctly before this time has elapsed, contact AMI for a return
authorization for evaluation. If there is any evidence of defective material or
workmanship the sensor will be replaced free of charge.
NOTE: Any evidence of abuse or physical damage, such as a torn membrane, will void
the warranty.
Instrument Warranty:
Any failure of material or workmanship will be repaired free of charge for a period of two
years from the original purchase (shipping date) of the instrument. AMI will also pay for
one way shipment (back to the user).
This warranty does not cover the sensor, which is covered by its own warranty (see
above).
Any indication of abuse or tampering will void the warranty.
