During the first quarter of 2018, Sound Solutions Products Ltd submitted three Series 2 tapping machines to PTB in Germany. All three machines successfully underwent the rigorous testing procedure for tapping machine conformance within PTB's own testing laboratory and as a result, on 17th April 2018, the Series 2 tapping machine achieved its PTB Type Approval. PTB is Germany's highest authority when it comes to correct and reliable measurements. This cements the Series 2 tapping machine as a high-quality product available for acousticians around the world.
