AtmoCheck® WELD O2 / CO2

for checking inert and forming gases

AtmoCheck® WELD O2 / CO2 is 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 because a lack of active gas components in the inert gas, which can be carbon dioxide or oxygen, will make the light arc unstable, leading to substandard welding.

AtmoCheck® WELD O2 / CO2 is 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 adsorbing surfaces so that the use of hydrogen as a reducing gas component is beneficial: this can be used in varying concentrations.

AtmoCheck® WELD O2 / CO2 is therefore 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. to:

AtmoCheck® WELD O2 / CO2 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.

AtmoCheck® WELD O2 / CO2 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.
