Pewatron’s PO2ES-103D is a rugged electrochemical cell with a weak acid electrolyte that can easily be adapted into the application. The lifetime of the cell exceeds 1200000 %Vol O2 hours and the end of life (EOL) is easy to detect. The sensor is lead-free and is conform to recent RoHS/Reach directives. Most industrial requirements for oxygen sensors call for a low-drift baseline, signal stability and ease of calibration. The basic PO2ES-103D sensor has a build-in 16 bit AD converter that delivers a highly stable, temperature independent signal with a resolution 100 ppm. The drift is less 1 % per month, averaged over 12 months. The PO2ES-103D sensor has a zero baseline 1500 ppm O2 and very stable, making it suitable for controlled atmosphere applications in a range from a few hundred ppm O2 and higher.
