The Argo-Naught 2010 is a state of the art, high spec oxygen monitor for weld purging. Its air and water-tight casing hermetically seals the electronics which prevents electrical emissions and sparks. Also, it will stop any contamination of the inside of the instrument, which considerably increases the longevity and accuracy of the sensor especially in wet or sandy environments. Its exceptional accuracy, light weight, easy operation, fast response time and quick sensor change make the Argo-Naught 2010 an outstanding oxygen monitor for all weld purging requirements.

It is important that the Argo-Naught 2010 Weld Gas Analyser is continually used during welding to monitor the weld purge levels. It will quickly identify any oxygen level drawn into the pipe volume that is being shielded with inert gas. Typically, customers choosing to purge pipes with gaps between the pipe end bevels, will tape up the gap prior to welding when they purge. When fabricators begin to remove the tape and their flow of gas is to low, argon will escape from the purge allowing atmospheric gases such as oxygen through the weld gap. The Weldwide Weld Gas Analyser will save the weld root by alerting the fabricator if the levels rise to an unacceptable level.

Customers who wish to improve their weld purging practices can request a visit or discussion with our weld purging technicians to see how our products will help them overcome all weld purging concerns and eliminate all future oxidised and discoloured weld roots.
