The ultrasonic pulse-echoer (UPE-HF 30) calculates the elastic modulus of materials by measuring the propagation speed of ultrasonic waves in the medium. It supports two measurement modes: echo mode and transmission mode.
| Models | Modes | Pulse type | Pulse amplitude | Pulse width | Maximum pulse repetition frequency | Bandwidth | Manuals |
| UPE-HF 30 | Single, double | Negative square wave | -400V~-25V | 25ns~6500ns | 5kHz | 1kHz~30MHz |
