Ultrasonic Thickness Gauge MT200
Overview:
1. Capable of performing measurements on a wide range of material.
2. Four transducer models.
3. Probe-Zero function, Sound-Velocity-Calibration function.
4. Two-Point Calibration function.
5. Two work modes: Single point mode and Scan mode.
6. Coupling status indicator showing the coupling status.
7. Auto sleep and auto power off function to conserve battery life.
8. Optional software to process the memory data on the PC.
9. Optional thermal mini-printer to print the measured data via RS232 port.
