Model 901 Portable Spot Check

O₂Analyzer

For Rapid Spot Checks of Oxygen Concentrations

MEASURE O₂ IN MANY APPLICATIONS

The Model 901 Portable Spot Check O₂ Analyzer is a battery-operated, portable oxygen analyzer used for the measurement of residual oxygen in gas blending, enclosed systems, bio reactors or any application where the sample of interest can be introduced to the inlet fitting of the analyzer, where it flows to the sensor.

Alternatively, the unit can be equipped with the sensor inlet open to the atmosphere and the entire unit placed in a closed system to be monitored for oxygen level. The sensor operation is not sample flow dependent, and accurate results are obtained on both static and flowing samples.

HEAVY DUTY, LONG-LIFE SENSOR

The sensor is a proprietary electrochemical type with a 5 year design life, with a measurement range of 0.1 to 100%. Excellent linearity through the entire range allows a calibration with one set point using room air. It is unaffected by high levels of background gases such as nitrogen or carbon dioxide. The Model 901 can be used for applications where the oxygen level is very high (50 to 100%), without overloading the sensor. It is unaffected by trace hydrocarbons or high levels of CO2, which can poison other types of sensors, and operates independent of flow rate.

BATTERY OPERATION

The Model 901 is powered by four AA alkaline batteries, or four rechargeable (optional) AA NiCad batteries.
