The stainless steel test body "Heinz" is used e.g. for pressure tests on gas and water pipes and offers four practical connections made of nickel-plated brass or stainless steel. They are used to connect the pressure sensor, to let in and drain water or gas and to connect the control manometer. When draining water, the DWZ2 - our digital water meter, can be connected with quick coupling. The test piece has an external thread of 2 ½" and is suitable for pressure tests up to 60 bar. All quick couplings are equipped with protective caps for safety and are thus protected against dirt or water. With the optional test adapters, a tight transition to many threads and fittings is achieved.
