The NO3D calibrated sensor cartridge should be replaced approximately twice a year (in typical operating conditions). Cartridge replacement only takes minutes - just remove the old cartridge, plug in the new, and enter the sensor code. CARTRICAL technology calibrates each electrode individually as well as calibrating all three electrodes to each other.
