Product Description

The apparatus provided comprehensive unit to perform the vibration experiments. Three different modules are provided upon which various experiments can be performed. The unit is self- contained to safely store spares. The students can easily assemble the experiments and study the theory of vibrations practically. Modular construction facilitates easy operation of unit and also, working of three batches simultaneously. Also, the work of assembly & dismantling is reduced to much extent, which is its distinct advantage over conventional common frame type units.
