Breakthrough Technology

Hummingbird’s unique Zirconia cell provides an accurate and fast response measurement in a design that gives an exceptionally long service life. With 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.

Having 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.

With a measurement range from 0.1-100% O2, the Zr743 is designed for general industrial oxygen measurements.
