Tapping Machine - HD2040 

HD2040 is an impact noise generator normalized for the measure of ceilings acoustic insulation.

Characteristics :

  • Aluminum structure (light weight, easy transport);
  • Interiortreated withsound absorbing material;
  • 5 in line hammers in hardened stainless steel undeformable;
  • Electronically controlled engine;
  • Falling speed and impact frequency of hammers constantly monitored to guarantee compliance with regulation;
  • Optical sensor and LED indicators indicate the proper functioning of each hammer;
  • Spacer for the verification of the fall height;
  • Integrated spirit level for the horizontal positioning; Radio–controlled drive;
  • Supply voltage: 100-240 Vac/rechargeable lithium-ion battery with integrated battery charger

According to : ISO 140-6, ISO 140-7, ISO 140-8, ASTM E492 and E1007
