Standard Tapping machine

Product name: Standard Tapping machine

Product model: SVLab 239

Manufacturer brand: SVLab

The SVLab 239 standard Tapping machine is a major equipment used for measuring building sound insulation and conducting laboratory research. It is mainly used to measure the sound insulation performance of building floor impacts, providing a stable impact sound source by simulating the sound generated by people walking on the floor or hitting objects.

This standard Tapping machine uses wireless radio frequency technology and can be remotely controlled.

SVLab239 can easily pass through walls and ceilings, and its integrated structural design not only ensures strength, but also achieves lightweight.

This product also supports battery and AC power supply, which can adapt to various measurement scenarios.

Functional Characteristics

Impact signal stability

Adopting a precise mechanical structure and closed-loop control system, ensuring high stability of the impact signal.

Wireless Remote Control

Adopting a 433MHz remote control, it has strong wall penetrating ability and a free field remote control distance of over 100 meters.

Impact Hammer Status Indication

Display the status of 5 impact hammers through LED indicator lights to ensure that the impact hammer falls normally.

Temperature control function

The standard Tapping machine is equipped with a motor overheat protection function to prevent damage to the motor caused by high temperatures.

Built in battery powered

This product is equipped with an internal battery pack (lithium type), which can help operators work without any cables. The battery automatically charges when connected to the main power supply. A fully charged battery can ensure 3 hours of continuous operation.

Support Manual Operation

The standard Tapping machine can not only be remotely controlled through a remote control, but also supports manual control operation through the operation buttons on the front panel of the instrument.
