What is the primary application of an amperometric cell?

The primary application of an amperometric cell is in the measurement of specific gases, particularly in environments where the monitoring of oxygen levels and combustible gases is crucial for safety. Amperometric cells work by measuring the electric current that results from an electrochemical reaction involving the gas being detected. In the context of oxygen deficiency meters, these sensors play a vital role in detecting low levels of oxygen which can pose a risk in various industrial settings. They ensure safety by providing real-time monitoring of oxygen levels, thereby helping to prevent hazardous conditions associated with insufficient oxygen and the presence of combustible gases.

The other options, while relevant to different aspects of industrial hygiene or environmental monitoring, do not align with the specific function of amperometric cells. For example, ozone sampling is typically done using other types of sensors or methods, not exclusively amperometric cells. Fiber type identification relates more to microbalance methods rather than amperometric measurement. Temperature correction in sampling generally involves different techniques ensuring accurate readings at various thermal conditions, rather than employing amperometric cells directly.
