Portable Instrument for testing materials with high attenuation of ultrasonic waves, as concrete, wood, plastic materials, constructions and coarse-grained materials.
The instrument is suited for testing materials with high attenuation of ultrasonic waves, as concrete, plastic materials with enhanced attenuation, constructions and coarse-grained materials in general. The principal feature of this equipment is its low operation frequency from 20 kHz to 1 MHz. The DIO 1000 LF kit includes one pair of low frequency transducers (1 pc. transmitter and 1 pc. receiver)
STARMANS low frequency transducers are single element transducers designed to work at frequencies of 50 kHz, 120 kHz, 200 kHz and 400 kHz. One pair of transducers consists of Transmitter and Receiver.
