The N-33 is the replacement sensor for the AN300 Portable Nitrogen Analyzer.
The N-33 is a replacement electrochemical oxygen sensor for gas analyzers. Under normal use, oxygen sensors have an expected service life of 36 months. The N-33 replacement sensor fits the following analyzers:
WARNING: Never expose gas sensors to pressure or you may cause damage and/or false readings. Damaged sensors will not provide accurate gas analysis. Most gas analyzers can be used to analyze a regulated gas sample flow, the contents of a gas cylinder, or the flow from a regulator. The flow rate of gas must equal 1-5 L/min. To produce this flow, a Flow Restrictor and Regulator may be required. A faulty Flow Restrictor can lead to a false analyzer reading. Flow Restrictors should be regularly tested with a Flow Meter. Inaccurate gas analysis can lead to serious personal injury or death.
|Output||10±3 mV in air at 25°C/77°F, sea level|
|Electrical Connector||Mating plug: Molex (PN 22-01-3037 or 22-01-2037)|
|Range||0–20.9% oxygen (79.1–100% nitrogen)|
|Accuracy||Within ±1% of full scale at constant temperature and pressure when calibrated with air (20.9% oxygen)|
|Shelf Life||24 months|
|Expected Sensor Life||36 months in air at 77°F (25°C) and 50% rh|
|Response Time||<6 seconds for 90% of final value|
|Operating Temperature||32–104°F (0–40°C)|
|Storage Temperature||32–122°F (0–50°C)|
|Humidity||0–99% rh (non-condensing)|
|Weight||1 oz (28.3 g)|
|Temperature compensation error is ±5% of full scale over the operating temperature range. Worst case tracking error (within the first hour after a maximum temperature step) is ±10% of full scale. (Gas samples must be brought to ambient temperature) Percent readout is only within ±1% at constant pressure (e.g. a 10% increase in pressure will result in a 10% increrase in full scale).|
