Ultrasonic

Ultrasonic Analyzer is a real-time spectrum, spectrogram, oscilloscope and octave RTA analyzer for your iPad. It provides a visual representation of many ultrasounds using a sampling rate up to 384kHz. The app can record, analyze and use slow down playback for sounds normally impossible to hear. The app can also analyze any imported audio file into a spectrogram context. 

Ultrasonic is a great tool for doing bearing lubrication testing and detecting air leaks. The ultrasonic sensor plugs directly into the iPad’s Lightning port. It is a highly directional sensor enabling very precise readings.
