METHOD OF MEASUREMENT:

ZIRCONIUM OXIDE SENSORS

The 

MODEL 221R

 utilizes zirconium oxide sensors, which provides reliable, accurate percent 

oxygen measurements for a general purpose environment.

•These sensors have up to a 10-year product life.  This eliminates the need to replace sensors every       
    6 months and the need to perform monthly calibrations, which drastically lowers maintenance  
    costs.
