Detail Tapping Machine, Model : HD 2040, Brand : DeltaOhm
The tapping machine HD 2040 is a noise generator to measure normalized
impact sound insulation of floors according to ISO 140-6, ISO 140-7, ISO 140-8, ASTM E492 and E1007.
It has 5 in line hammers operated by means of a camshaft engine controlled
by an electronic system. The falling speed of the hammers and the frequency of impacts are constantly monitored to ensure compliance
with the legislation. LED indicators on the front panel indicate the correct operation of each hammer.
The hammers are made of hardened stainless steel and are non-deformable
over time.
It is equipped with hight-adjustable feet with rubber base. On the back cover it is fitted with a distance spacer to verify the height of fall. The distance spacer enters into place with a slight pressure, pull to drive it out. The feet can be rotated under the base to reduce the size of the package and facilitate the transportation of the machine.
The starting and stopping of the machine is via a button on the front
panel or remotely via the supplied remote control. The antenna is
screwed to the connector on the top of the machine, unscrew it to store the machine in its case.
100 ... 240Vac mains supply or rechargeable lithium ion battery housed
inside the machine. The charger is built-in and the battery recharges
automatically when the machine is connected to the mains.
The aluminium construction reduces the weight of the machine and makes it easily transportable.
A bubble level on the cover of the machine allows you to position it
perfectly in the horizontal plane.
