Modern solutions in unique design

Discover our range of residual oxygen analyzers, designed for precise and reliable oxygen measurement in orbital welding applications.

From the compact PRO2 Stick with its intuitive “shake-to-measure” function and Bluetooth connection to our durable PRO2 Expert with zirconium sensor technology and unique LED ppm indication, OrbitalService offers the right solution for every requirement.

Our latest innovation, the PRO2VisionH2, features our own advanced optical quench sensor technology, specially developed for hydrogen and forming gas applications. It delivers fast, accurate ppm measurements, requires no heating phase, and is insensitive to humidity, pressure, and temperature variations.

All analyzers offer modern interfaces, wireless operation, rechargeable batteries, and worldwide power compatibility with 100–240 VAC autorange supplies.

PRO2VisionH2

The next generation of oxygen measurement for hydrogen applications.

The PRO2VisionH2 is one of the few oxygen analyzers worldwide capable of measuring residual oxygen in hydrogen-containing gases, from 1000 ppm down to 1 ppm.

Featuring our own advanced optical quench sensor technology, it delivers fast, precise, and stable measurements without any heating phase. Unlike conventional sensor technologies, it is insensitive to humidity and compensates for pressure and temperature changes, ensuring reliable results in the most demanding orbital welding environments.

With its modern touchscreen interface, wireless connectivity, and intelligent data management, the PRO2VisionH2 sets a new standard for professional residual oxygen analysis.
