I need to change the Oxygen and Helium cells in my ATA Pro, how do I do this?


The very simple process of sensor replacement is outlined in the video below

ATA: (Pro) - 1. Sensor Change from Analox on Vimeo.

  • Following a sensor change you should carry out a helium zero and span to match the helium cell to your device 
  • If your device is reporting incorrect values of helium it may be necessary to carry out a helium calibration

The video below demonstrates helium cell replacement and full calibration. 

Please note:  Prior to setting the helium span value, the device should be exposed to a span gas for a minimum of 2 minutes.
