Abstract : A mixed-gas scuba regulator for use as a component part of a standard mixed-gas scuba is evaluated. The unit's flow characteristics (constant-mass-flow with increasing depth), when used in conjunction with changeable orifice plates, were found to be satisfactory in all respects. The practicability of using a single orifice plate and varying regulator pressure to obtain desired flows is demonstrated but the selection of a single, optimum orifice plate is left for further test and development. The regulator's weight and bulk are slightly larger than desired and it is recommended that efforts be made to reduce them. (Author)
