Indicator of frequency and sound pressure in ultrasonic band in liquid medium I100-33
Unit is designed for indicating of ultrasonic oscillations presence in liquid medium in 100-99000 Hz band.
Range of measurement is divided to two sub-bands:
- 100 - 30 000 Hz.
- 30 000 - 99 000 Hz.
Frequency is measured by digital frequency meter, sound pressure is displayed at indicator.
Complete set consists of:
- Indication unit
- Hydrophone
- Manual
