ALSPEK H may be interfaced to any Foundry Degassing Unit (FDU) and used to measure hydrogen during the FDU treatment. The sensor responds within seconds, allowing closed loop control of dissolved hydrogen at any prescribed level.

Cost benefits of FDU control:

Saves gas. Excessive degassing, in order to compensate for factors such as ambient humidity, is avoided

Saves time. Reduction in FDU treatment times result in higher output and efficiency

Reduces scrap due to gas porosity or shrinkage
