Monitoring and control device for light diving equipment, requires oxygen-limiting valve for blocking/locking oxygen setting of gas selection valve

摘要

The monitoring and control device for light diving equipment has a gas selection valve for selective supply of a supply hose (2) with respiration gas (22) or oxygen (26), and an oxygen limiting valve (7) for blocking/locking the oxygen setting of the gas selection valve when the diving depth exceeds a given value.
