1.4 Applications
The
MIXCHEK is specifically offered to the diving industry
where specific mixtures of Helium and Oxygen in air are required for
technical diving. The
MIXCHEK will allow on-site confirmation of gas
mixtures prepared for divers. It is also useful in the gas mixing process
during cylinder charging where adjustments to the gas composition can
be made based on the real-time analysis of the gas mixture.
