The measurement method for welding technology (patent pending) is far superior to the conventional methods.

This ORBmax residual oxygen meter sets a milestone for fast, exact detection of residual oxygen, and with it complete documentation of these parameters. At the same time, the new measuring method results in greater efficiency and higher quality.



  • No warm-up time required
  • Quick response
  • High measurement accuracy
  • Measurement of residual oxygen level during the welding process
  • No uncontrolled increase of the measurement during the welding process
  • Measurement of forming gas with variable hydrogen content without mode change
  • Measurement of the residual oxygen value in all gas mixtures
  • Measured value recording on SD card
  • User-friendly touchscreen
  • Liquid-resistant sensor
  • Alarm mode with beeper and changing colour of the display (green/red)
  • Protection class IP32
  • Setable alarm value and saving interval
