86213 Ultrasonic Thickness Gauge
Non-destructive testing for metals, glass, ceramics, and plastics
The 86213 precision ultrasonic thickness gauge delivers fast, accurate measurements.
It features two measurement modes: QC Mode and Statistics Mode, a high-sensitivity dual-crystal probe, and switchable automatic gain.
The 86213 ultrasonic thickness gauge is user-friendly and operates on the principle of ultrasonic pulse reflection to measure material thickness. It is compatible with four probe types—standard, micro-diameter, coarse crystal, and high-temperature probes—and is ideal for measuring the thickness of metals (like steel, aluminum, copper), plastics, ceramics, glass, fiberglass, and other ultrasonic-conductive materials.With a dedicated timing chip, it offers a resolution of up to 0.01 mm.

Features
High-sensitivity dual-crystal probe
The probe uses a dual-crystal transducer, with two independent crystals separated by an acoustic barrier—one for sending ultrasonic pulses and the other for receiving them.It minimizes signal clutter, and its stainless steel housing ensures durability.
Four interchangeable probes with automatic recognition
The gauge works with four types of probes: standard, micro-diameter, coarse crystal, and high-temperature. It automatically identifies the probe type and adjusts the display interface accordingly.
Switchable automatic gain
For materials with weaker ultrasonic transmission, the gauge allows users to adjust the gain, amplifying signals to ensure accurate detection and measurement.
Precision timing chip for fast, accurate readings
The device calculates material thickness based on sound velocity and echo time. The precision timing chip ensures rapid and precise measurements.
Coating penetration measurement mode
When a coating or paint layer is present, the standard probe's special mode can measure the true substrate thickness without removing the coating.
Stores up to 999 data points
Up to 999 test results can be saved and accessed anytime, minimizing data loss.
Customizable storage of 18 sound velocity settings
Users can store and modify up to 18 sound velocities (9 each in "Set by thickness" and "Manual input" modes) for more convenient thickness measurements.
Set by thickness interface
Manual input interface
Bluetooth app functionality
The built-in Bluetooth module connects to a mobile app for expanded data storage and easy sharing of measurements.
High accuracy and resolution
With an accuracy of ±0.05 mm and resolution of 0.01 mm (for 0.8 mm–10 mm thicknesses), the gauge meets national metrology standards.
Measures a variety of materials
Suitable for both metallic (steel, iron, aluminum, copper) and non-metallic (ceramics, plastics, glass) materials, as long as the opposing surfaces are parallel or coaxial during testing.
QC Mode and Statistics Mode
QC Mode lets users set upper and lower limits, providing PASS/NG alerts. Statistics Mode calculates max, min, and average values.
Preloaded sound velocities for multiple materials
The gauge includes preset sound velocities for common metals (iron, copper, aluminum) and non-metals (plastics, ceramics, plexiglass), saving users time.
Ergonomic design with non-slip silicone keys
Encased in an ABS plastic shell with non-slip silicone keys, the device offers a comfortable, secure grip.
LCD Screen offers users relaxing reading
Inch/mm switchable
