The B-Smart® Sensor Exchange Program allows users to replace pre-calibrated sensors in the field, eliminating the need to send the instrument in for calibration. With the B-Smart®Sensor Exchange Program, you receive factory-calibrated sensors, just plug them in and continue to use your instrument - there's no down time and it saves time and money. For use with Fyrite® INSIGHT® Plus, Fyrite® InTech®, PCA®3, Monoxor® Plus and Fyrite® INSIGHT analyzers.
