Description and Details
The MIX 4 and MIX 5 safety gas mixers are designed to provide a precise mixture of medical gases (O²/N²O or O²/Air). These mixers offer improved accuracy over previous models (MIX 2 and MIX 3) due to their twin tube design. They are primarily used in workrooms, operating theatres, and examination rooms. Key features include the ability to deliver very low flow rates, high precision through twin reading tubes, separate gas flow readings, and individual calibration of flowmeters. The devices are insensitive to supply pressure variations and include safety regulations to prevent oxygen concentrations below 20%. They also feature a complete nitrous oxide cut-off in case of oxygen supply failure, an audible alarm for low oxygen supply pressure, an auxiliary oxygen supply outlet, and an integrated oxygen bypass push button.
