Phase II UTG4000 Ultrasonic thickness gauge featuring A/B Scan and Thru Coating Capability

Phase II UTG4000 Ultrasonic Thickness Gauge with A & B Scan and Thru-Coating Measurement

This advanced ultrasonic thickness gauge features color waveform A-scan and time-based B-scan for precise measurements. It is equipped with thru-coating capability, making it ideal for applications where ordinary thickness gauges cannot provide accurate readings.

The Ultrasonic Thickness Gauge with Thru‑Coating Capability is used by non‑destructive testing (NDT) inspectors, maintenance technicians, and quality control engineers to measure the thickness of base materials through existing surface coatings. Ultrasonic gauges with thru‑coating capability use pulse echo technology to distinguish the base metal echo from coating echoes, allowing inspectors to obtain true substrate thickness without removing paint or protective layers, a method described in industry NDT resources explaining the advantage of thru‑coating ultrasonic modes for corrosion and wall‑loss inspection.

Professionals value thru‑coating thickness gauges for their ability to deliver accurate readings through coatings, improving inspection efficiency and reducing surface preparation time compared with traditional methods that require coatings removal. These instruments support quality control and safety compliance in industries such as oil and gas, shipbuilding, petrochemical processing, and structural maintenance by providing reliable non‑destructive thickness verification on coated pipelines, tanks, and structural steel surfaces.

Versatile Measurement Options

The UTG-4000 provides basic thickness measurement, scan mode with Min/Max visualization, GO/NO GO display, adjustable sound velocity, and thru-coating functionality. This makes it perfect for both metallic and non-metallic materials in demanding environments.

Accurate and Simple Calibration

The device delivers accurate readings in either inches or millimeters. Calibration is straightforward and can be done using a known thickness standard or by inputting the sound velocity of the material being tested.

Q&A

What materials can the UTG-4000 measure?

The UTG-4000 can measure metallic and non-metallic materials such as aluminum, titanium, plastics, ceramics, and glass, as long as the surfaces are parallel and suitable for ultrasonic testing.

Does the gauge require a couplant?

Yes, the direct contact pulse/echo method requires a couplant. Propylene Glycol is commonly used, but other compatible substances can also work.

Can readings be displayed in both metric and imperial units?

Yes, the gauge can display thickness measurements in either millimeters or inches after simple calibration.

Does the UTG-4000 support data output?

Yes, it can retain memory, output to printers, PCs, and portable handheld devices for data recording and analysis.

QUICK TIP:

Maintenance:

1. Keep the gauge, probe, and cable clean of dirt, dust, and fluids to prevent premature wear.
2. Avoid caustic liquids, alcohol, or viscous fluids to prevent corrosion of the cover and display window. Clean only with water.
3. Prevent scratches on the probe surface. A damaged probe can cause unstable readings.
