The Sonospot - Snaphone, manufactured by Sonotech® is a sound detector of emissions in the ultrasonic frequency range caused by compressed-air leakages and electric partial discharges. It allows a reliable and precise detection even over longer distances. Plus, it is designed for the rapid, reliable and cost-effective detection of seal failures and the smallest of leaks from compressed air systems and networks, industrial equipment and machinery and covered pipes with restricted access. It has a high sensitivity and precise directional of the sensor that allows the detection of electrical partial discharges and damages to electrical insulation with a robust and transparent reflector for optimal sight and an easy transportation.
