Oxygen Gas Analyser And Accessories

Our Oxygen Analysers ensure that residual oxygen levels remain below critical thresholds—typically 50 ppm—during stainless and titanium GTAW root welding. Zirconia sensors heat to 700 °C, delivering full-scale ppm response in under 8 s, while galvanic sensor versions offer lower initial cost and six-month cell life for general pipe welding.  

Gas analysers incorporate flow-controlled sample pumps and inline particulate filters, protecting sensors from dust and pickling fumes. Auto-calibration prompts guide technicians through atmospheric zero and 99.999 % nitrogen span checks, storing calibration dates for ISO audit compliance.  

Data-logging modes record up to 2 000 time-stamped oxygen readings, downloadable via USB for weld trace packs. ABS enclosures carry IP 65 ingress ratings, and silicone keypad overlays allow gloved operation. Each oxygen analyser ships with sample tube, quick-couple fittings and padded carry case.
