Model 3000ZA2G combines the reliability, flexibility and ease of use of the 3000 platform with the dynamic functionality of zirconium oxide (ZrO2) sensing technology to offer a perfect solution for universal oxygen monitoring in inert gas applications.
Zirconium Oxide
This unit has a non-consuming, solid state sensor. Under high temperature, the difference in oxygen partial pressure between the measuring and reference surfaces will create a millivolt differential logarithmically proportional to the difference in PO2. An instrument air reference is used in this unit and the electronic circuitry conditions in the voltage differential and uses an integral microprocessor to provide a volumetric reading and other electronic functionality.
Microprocessor Based
The units microprocessor-based electronics utilize menu-driven functionality. Users are provided a large luminescent LCD display and 2 x 20 vacuum fluorescent displays to show all menu functions and parameters. A preamplifier with multiple stage gains supports a wide dynamic operating range with reliable performance.
