The probe of Mikrosize’s ultrasonic thickness gauge for coating measurement emits high-frequency ultrasonic pulses, which travel through the coating with the help of a couplant. When ultrasonic signals hit coating boundaries with different material densities, part of the energy bounces back as reflected echo pulses, while the remaining waves keep travelling through the material.
These reflected echo signals go back to the probe and get captured by the built-in sensor. The device processes returned signals and calculates the travel time of ultrasound inside the target coating.
With the formula: Thickness H = V × T / 2, where V stands for known coating sound velocity and T is the ultrasonic propagation time measured by the unit, users can acquire accurate coating-thickness readings. This core technology underpins the reliable measuring performance of Mikrosize instruments.
Product Highlights of Mikrosize Ultrasonic Thickness Gauge
Multi-Layer Thickness Testing
This unit supports simultaneous measurement of up to 3 material layers (coating-to-coating plus substrate layer) across steel, aluminum, plastic, fiber-reinforced composites and more. It delivers non-destructive coating thickness testing without scratching or damaging sample surfaces — one major competitive advantage for Mikrosize industrial measurement solutions.
Micrometer-Level Measurement Accuracy
Fitted with high-speed ADC chip offering 1 μm resolution, paired with fine-tuned intelligent measurement algorithms. It generates consistent, trustworthy readouts for everyday industrial inspection tasks.
Intuitive HD Touch-Screen Interface
Comes with an 800 × 480 dot-matrix IPS color display. The user-friendly dashboard enables one-tap parameter configuration and quick sound velocity adjustment, helping operators boost on-site testing efficiency.
Visual Inspection with Real-Time Echo Waveform Display
Live echo waveforms are shown on screen, together with a movable blue cursor. Operators can directly observe echo feedback, a standout visual feature built into this coating thickness measuring device.
Broad Compatibility for Industrial Materials
- Automatic gain switching: auto-optimizes signal strength for different workpiece materials
- Three practical sound velocity setting modes: pre-selected known-material library, thickness-derived calculation, and manual value input
- Target gate interval locking: suppresses undesired waveform noise and improves precision for multi-layer coating inspection
Continuous On-Site Measurement Mode
Operators can reposition the probe during testing and lock stable optimal readings in real-time. This function is built to match dynamic industrial non-destructive testing workflows.
Heavy-Duty Military-Grade Build Quality
The enclosure is precision forged from aviation-grade aluminum alloy. This signature construction balances light weight and strong shock resistance, making the gauge suitable for rough, harsh workshop and field working conditions.
