Oxy EVO Oxygen Analyser

Oxy-EVO Oxygen Analyser

Mains powered analyser, 100VAC to 240VAC (50/60Hz) autoranging

Precise purging is essential for controlling weld quality, particularly when welding high-alloy, corrosion-resistant materials. Our oxygen analysers 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 specified otherwise, 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 oxygen content in the relevant range for welding <30ppm within +/- 2ppm precision.
