Sensor for Pro CO Alarm Analyzer | 9501
Replacement sensors for the Nuvair Pro CO Alarm series of carbon monoxide analyzers and multigas analyzers with CO sensors. Please make sure to select the correct sensor for your analyzer. Depending on the year of manufacture, your sensor has a range of 0-50 ppm or 0-300 ppm. Sensors are not interchangeable.
Replacement sensors for the Nuvair Pro CO Alarm series of carbon monoxide analyzers and multigas analyzers equipped with CO sensors. Depending on the year of manufacture, your analyzer uses one of two different sensors. Because of analyzer firmware programming, only the correct replacement sensor will work.
There are two methods to determine which replacement sensor is needed for your analyzer:
- Remove the four screws on the front face of the analyzer. Identify on the label of the sensor (FSc 220 or FSc 33).
- Turn the analyzer on and wait for the warm-up cycle to complete. The analyzer will read 000.
- Hold the [Prog] button for 2 seconds.
- Press the [On/Off] button to scroll through the settings until the display reads [Fct].
- The number shown by the display should match the FSc number labeled on the sensor.

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.
