Oxygen monitor QuadroLine® Oxi 296

WTW analog oxygen monitor QuadroLine® Oxi 296

Performance by a compact design - analog oxygen monitor to be installed on control panels with lightning/overvoltage protection and galvanized separation of the inputs/outputs

  • User friendly and effective with the 1-key calibration via the OxiCal® procedure
  • Safe operation thanks to the integrated lightning protection and galvanically isolated inputs and outputs
  • Reliable measurements by compressed air compensation and complete sensor monitoring

The QuadroLine® Oxi 296 has a complete sensor monitoring system with relay switching and optical warning message. With the proven OxiCal® procedure, you use only one operation key to perform an automatic and quick air calibration of the sensor.

With the QuadroLine® monitor Oxi 296, WTW has realized comprehensive lightning/overvoltage protective measures in the electronic layout, which make preswitched, high cost protective systems superfluous. This protects measuring systems reliably against overvoltage and secondary lightning effects, even if the sensor is used outside.
