Air Calibration:
Calibration is essential prior to every use. For oxygen mixtures above 50% oxygen always
calibrate in 100% oxygen before use. This assures minimum deviation and greatest accuracy.
For regular use expose the analyzer to clean room air and adjust the calibration knob until the
display reads 20.9%.
The analyzer is now ready for oxygen measurement.
WARNING:
The analyzer is sensitive to oxygen partial pressure. Calibration must always be carried
out at the same pressure as the oxygen measurement.
Oxygen Calibration:
Obtain the 100% oxygen from a certified Distributor and measure the gas using a 100 ml to
500 ml per minute flow rate. Be sure to allow the reading to stabilize.
Operation:
The Oxygen Analyzer comes complete with a sensor flow cap/restrictor that allows you to read
directly from a cylinder valve. For the external sensor Oxygen Analyzer the sensor cable plugs
into the right side of the Analyzer and has a secured mini-phone jack that connects to the
sensor securely.
You should check the calibration with 100% oxygen periodically and adjust as necessary. If for
any reason the Analyzer does not calibrate within specifications the oxygen sensor should be
