Frequency meter ICh-5 (ICh 5, ICh5)
Frequency meter ICh-5 are designed to measure the frequency of oscillations of sound and ultrasonic frequency ranges.
The units are designed for use in laboratories and workshops.
Main technical characteristics
Measurement frequency range 10Hz-100000Gts divided into ten sub-bands: 0-100Hz-200Hz-500Hz-1000Hz, 2000Hz, 5000Hz, 10000Hz, 20000Hz, 50000Gts-100000Gts.
