TRUE METRIX PRO Blood Glucose Monitoring System Test Strips feature TRIPLE SENSE TECHNOLOGY, the system that provides proven accuracy and confidence in results. No Coding Technology eliminates the need for coding of the meter. Code is assigned during manufacturing process and is printed onto contacts on end of test strip. Meter reads code on insertion. Advanced technologies (the meter, a complex algorithm, chemistry and electrodes) on the test strip work together as part of the TRUE METRIX PRO system to produce accurate results.
