Zr733 recovery from oxygen shock


Hummingbird’s unique zirconia cell offers an accurate and fast response measurement in a design that gives an exceptionally long service life. Offering an excellent response time and recovery from oxygen shock, Hummingbird’s modern inhibited catalyst zirconia sensor technology offers a significant reduction in cross-sensitivity to trace combustibles. Offering a wide sensitivity to oxygen, from trace ppm levels to 100% O2, zirconia technology exhibits a faster recovery time when exposed to high ppm levels of oxygen in comparison to a wet electrochemical sensor.
