Welcome to ANV Measurement Systems

Rion, who are amongst the two largest manufacturers of sound and vibration measurement instrumentation in the world, were established in 1944 to develop commercial products based on the research carried out at the Kobayasi Institue of Physical Research in Tokyo, Japan. Rion still maintain strong links with the Kobayasi Institute which is now a leading centre for acoustic and vibration research. Rion instruments, including the microphones, are designed and manufactured to the highest standards by Rion in Japan and uniquely combine cutting edge technology with reliability and ease of use. In addition to sound and vibration instrumentation, Rion also design and manufacture precision medical instruments and hearing aids.
