Multi-Mode Thickness Gauge MT180/MT190
The MT180/MT190 is a multi-mode ultrasonic thickness gauge that operates on SONAR principles, delivering high-precision thickness measurements with accuracy up to 0.1/0.01 millimeters. This versatile instrument features pulse-echo mode for flaw and pit detection, and echo-echo mode to eliminate paint or coating thickness from measurements.
Key Features
- Dual operating modes: Standard testing mode and Through coating mode
- Compatible with diverse materials including metals, plastics, ceramics, composites, epoxies, glass, and other ultrasonic-conductive materials
- Specialized transducer models for coarse grain materials and high-temperature applications
- Two-point calibration and probe-zero calibration functions
- Coupling status indicator for optimal measurement conditions
- USB output with data processing software capability
