The OxyTechw² RDO Pro-X includes an optically active cap that needs replacement approximately every 2 years. Replacement is very simple and takes only a few minutes.
The cap includes a microchip that carries full details of its calibration coefficients along with a clock that reports on cap life. This information is automatically transferred to the sensor when the new cap is installed, meaning that there is no need for any manual programming or setup.
