Advanced Ultrasonic & Magnetic-Eddy Current Coating Thickness Gauge: Complete Solution for multi-layer coating thickness measurement
Ultrasonic coating thickness gauge marks a major advancement in non-destructive testing (NDT) for surface finishing and quality assurance. As a professional industrial thickness measuring instrument, this tool delivers precise readings for paint, plastic and other coating systems applied onto plastics, metals, wood, glass and ceramic substrates. One standout capability is performing non-destructive multi-layer coating measurement of up to 8 separate coating layers in one go, without damaging test samples. This functionality brings huge value for quality control within complex manufacturing workflows where multiple protective or decorative finishes are applied.
Supplied by trusted manufacturers such as Mikrosize, this advanced gauge leverages innovative ultrasonic technology to handle tricky materials that defeat many conventional test tools. It offers reliable, repeatable results on GRP (glass-reinforced plastic / fiberglass), CRP (carbon-reinforced plastic) components and low-temperature steel substrates. That makes it indispensable across aerospace, automotive, marine and general industrial manufacturing, sectors seeing rising adoption of composite materials.
Beyond ultrasonic multi-layer inspection, many industrial teams also need a practical handheld instrument for metal coating and plating thickness testing. For these jobs, the iCoat-200 Coating Thickness Gauge serves as a robust dual-principle workhorse. It integrates both magnetic induction and eddy current thickness measurement methods: users can test non-magnetic coatings over magnetic metal substrates as well as non-conductive coatings built on non-magnetic metal substrates. The unit fits well for precise measurement of coating and plating thickness on metal components, plus coating inspection on chemical-equipment surfaces.
Measurement Principle: Intelligent Ultrasonic Pulse-Echo
The core working mechanism of the ultrasonic model relies on refined ultrasonic pulse-echo technology. An intelligent coating-thickness ultrasonic sensor connects to an industrial tablet or PC acting as the evaluation unit. The sensor works as both signal transmitter and receiver. It sends high-frequency ultrasonic pulses through coupling gel or fluid into the layered coating assembly. Pulses travel through each layer and reflect back at every material-to-material interface. The sensor captures these returning echo signals. Built-in software calculates time-of-flight for each reflected pulse and converts those time values into accurate individual layer-thickness outputs.
Comprehensive Evaluation and Data Management Software
The full power of this NDT thickness measuring equipment comes from its intuitive, robust testing and data-management software package. The UI shows real-time A-scan ultrasonic waveform display and enables deep signal analysis on a high-resolution flat-panel monitor. Operators can freely adjust all measurement parameters to match project requirements. Users can store standalone A-scan files, then clip or mask target regions to run granular post-measurement analysis.
Mikrosize-provided platforms feature complete data-handling workflows. All measured datasets can be sorted systematically, exported as plain-text or Excel files for downstream statistical review, and compiled into formal PDF measurement reports. To support audit trails and QA compliance, technicians may attach descriptive notes and reference photos alongside raw measurement data for full traceable documentation.
Key Features and Operational Advantages for Ultrasonic Gauge
At its core sits proprietary SIDSP® (Sensor Integrated Digital 32-bit Signal Processing) technology. This solution processes measurement signals rapidly while maintaining high accuracy and excellent repeatability — critical for high-volume production-floor environments. Test speed reaches over 40 measurements per minute; users trigger acquisition and receive stable readings in roughly one second.
Practical mechanical design solves common on-site pain-points. A minimal measuring spot diameter of only 5 mm supports inspection of small-size parts and highly curved workpieces that are difficult for competing gauges. Speed, precision and wide material compatibility combine to make this instrument essential for facilities prioritizing top-tier coating integrity and quality standards.
Spotlight: iCoat-200 Handheld magnetic eddy current coating thickness gauge
Complementing the ultrasonic multi-layer system, the iCoat-200 Coating Thickness Gauge brings flexible handheld testing for metallic substrates. Below are its core product features:
Two measurement modes: Continuous measurement and single-shot measurement to suit spot checks or large-area scanning tasks.
- Three selectable measuring modes:
- High-precision measuring mode: computes averages from multiple readings and auto-filters outlier suspicious data points for improved accuracy and stability.
- Fast measurement mode: delivers real-time scanning function for rapid batch inspections.
- Typical Applications of iCoat-200
- Carry out precise measurement of coating and plating thickness on metal components across fabrication and finishing lines.
- Detect coating-layer thickness for surface protection of chemical-processing equipment.
Closing Thoughts
Choosing between ultrasonic multi-layer coating thickness gauge and magnetic-eddy current coating thickness tester depends heavily on your substrate type, layer count, and production-floor workflow. Ultrasonic systems excel at multi-layer setups including composites, plastics and wood. Meanwhile, the portable iCoat-200 covers high-volume metal-part coating and plating inspection with dual-principle magnetic / eddy-current capability. Combined, these instruments cover most common industrial coating thickness testing requirements for modern manufacturing quality-control teams.
