AtmoCheck® WELD O2/CO2

AtmoCheck®WELD Forming Gas Analyzer

for checking inert and forming gases

A handy battery-operated analyser that is ideal for use in welding and for monitoring high-purity gas supply, e.g. in the semiconductor industry and pipeline construction. Checking the inert and forming gas is crucial. A lack of active gas components in the inert gas, such as carbon dioxide or oxygen, will make the light arc unstable, leading to substandard welding.

Designed for checking the residual oxygen level in inert and forming gases. Oxygen can be absorbed not just from the ambient atmosphere but also by absorbing surfaces. The use of hydrogen as a reducing gas component is beneficial, it can be used in varying concentrations.

Is suitable when using H2 levels of up to 10%. In practice, regular testing of standard gasses and gas mixtures is needed to verify their precise composition and purity in use, such as e.g. :

is used for optimised monitoring of inert gas mixtures containing CO2. At the same time both O2 and CO2 concentrations are accurately measured and recorded.

excels with easy operation, short measuring times, and low gas volume sample requirement. The integrated data logger supports traceability and provides complete documentation.

The AtmoCheck® software permits fast, uncomplicated communication, and is safe and easy to use. It is equipped with all facilities for converting handwritten measurements to electronic records.
