Ultrasonic Thickness Meter TM-8819-T6
Advanced ultrasonic thickness measurement device designed to eliminate coating thickness interference for precise material measurements.
Applications
Ideal for measuring thickness and corrosion in pressure vessels, chemical equipment, boilers, oil storage tanks, and various industrial components. Serves industries including petroleum, shipbuilding, power stations, and machine manufacturing.
Compatible Materials
Steel, Cast iron, Aluminum, Red copper, Brass, Zinc, Quartz glass, Polyethylene, PVC, Gray cast iron, Nodular cast iron, and many other industrial materials.
Measurement Principle
The digital ultrasonic thickness gauge determines material thickness by precisely measuring the time required for ultrasonic pulses to travel through the material, reflect from the back surface, and return to the transducer. Advanced algorithms calculate thickness by accounting for sound velocity in the specific material.
Key Features
- Dual measurement modes: Pulse-Echo for flaw detection and Echo-Echo for measurements eliminating paint or coating thickness
- High emission power and broad receiving sensitivity compatible with various frequency probes
- Effective measurement of rough surfaces including cast iron applications
- Automatic memory for material codes and sound velocity values
- Coupling symbol indication during measurement
- Manual or automatic power off functionality
