The DXTR is a manually operated tool used to test the function of the non-return valve on commercial diving helmets as an alternative to oral testing. It improves efficiency while providing safe and sanitary testing of your diving equipment.
The DXTR is made from high quality diver-breathing-grade materials and reduces the chance of pathogens entering the diver's air train. The compressible bulb is a first-time-use scientific gas sampling bulb ensuring that it has not been made from reconstituted rubber that may contain hydrocarbons. Other components may be familiar to commercial divers, such as EGS breathing hose, fittings commonly seen on dive umbilicals, and a high-quality stainless steel ball valve commonly used un diving manifolds.
