OM10 ppm Oxygen Analyser for Weld Gas

The OM10 is the state of the art, easy to use ppm Oxygen Monitor for weld gas.It has an extremely fast response and a very high accuracy from 1ppm to 100% measurement. Ideal for use in welding enclosures/gloveboxes.

The analyser is the preferred standard for monitoring Oxygen in Arc welding gas, whether working with Stainless Steel, Duplex, Titanium or other high alloy steel. The OM10 achieves this without compromising on simplicity or sturdiness.
