The Measuring principle:
The Zircondioxid sensor is the ideal detector for the measurement of Oxygen in gases without
combustible impurities. The Zircondioxid sensor can be installed in the housing of the Oxygen
Analyser AMS 3220 . Using a calibration adapter with the Zircondioxid sensor, the Zircondioxid sensor can also be installed directly in a process gas pipe. This setup allows easy supply of calibration and reference gas to the sensor by using a separate pneumatic unit. In combination with the optional, time controlled auto-calibration feature the already high accuracy and reproducibility of the Oxygen Analyser AMS 3220 is improved further.
The Measuring system:
A long list of options allows to adapt the Oxygen Analyser AMS 3220 for almost every application.
Four measuring ranges with automatic switch-over and digital measuring range recognition can be set freely within the maximum measuring range. The software for remote control and remote service with access via the customer computer network further increase the flexibility of the Oxygen Analyser AMS 3220 in a application.
