Nor277 Tapping Machine
Retractable feet
Battery or mains operated
Meets latest sound power standards
The tapping machine Nor277 is the third generation of tapping machines from Norsonic for performing standardised impact noise tests (foot fall noise). It incorporates all the experience from the former generations into a compact, light, yet a rugged unit with the construction based on an extruded aluminium chassis. The hammers are made of harden stainless steel, ensuring non deformation of the hammer shape even after years in use. The unit weight is only 10 kg including the optional battery. Retractable feet ensure easy transportation and storage.
The unit has the required five hammers each weighting 500g, with a fall height of 40 mm and 100 ms between each hammer impact. A crystal-controlled servo system ensures the correct tapping frequency is always maintained and temperatures. A level gauge mounted on the top helps the user to align the unit when adjusting the fall height.
