Oxygen analysers

Oxygen analysers by Orbitec

The first step to a perfect weld joint


Precise purging is essential for controlling weld quality, particularly when welding high-alloy, corrosion-resistant materials. Our oxygen analyser can be connected to our controllers for monitoring ID purge quality as part of the programmed weld schedule parameters (except Oxy Smart). The entered oxygen value (in ppm) in the controller is arbitrary. If not otherwise imperatively prescribed, a value of < 30 ppm is generally sufficient at the beginning of the welding process. Welding will not commence until the measured value drops below the programmed threshold. The analysers are calibrated to measure in the for welding relevant range below 30ppm up to +/- 2ppm precise.


High preciseness.

Easy operation.

  • Low annealing colouring guaranteed
  • Fast response times
  • High measuring precision
  • Easy application
  • Measuring of inert gases and gases with H2 proportions

Indispensable for top quality

Examples of the annealing colouring levels versus residual oxygen content are shown below:

7 ppm = 0,0007%

27 ppm = 0,0027 %

500 ppm = 0,05 %
