Product Overview
The Qili UT600 Ultrasonic Thickness Gauge utilizes the pulse reflection ultrasonic principle and is professionally designed to measure the thickness of various materials that can conduct ultrasonic waves, such as metals, plastics, ceramics, and glass. Equipped with a professional timing chip, the instrument offers a high resolution of up to 0.001 mm. It enables rapid thickness measurement by simply placing the probe on one side of the object under test, making it suitable for various fields including industrial manufacturing and quality inspection. It is a reliable partner for thickness measurement.
Product Features

3. On-Demand Gain Switching: Users can select the appropriate gain based on material type and thickness, enabling multi-material measurement with a single device.
4. Ultra-Wide Measurement Range: Capable of measuring thicknesses from 0.8mm to 800mm, delivering fast and precise results.
5. QC Judgment Function: Determines whether the tested object is qualified based on preset upper and lower limits, enabling rapid quality inspection.
6. Statistical Function: Automatically calculates the maximum, minimum, and average values of measurements, providing clear and concise data overview.
Working Principle
The ultrasonic thickness gauge operates on the pulse-echo ultrasonic principle for measurement. It works by emitting an ultrasonic pulse into the material being tested through a probe and receiving the echo reflected from the opposite surface of the material. A specialized timing chip within the instrument precisely calculates the propagation time of the ultrasonic wave through the material, thereby determining the material's thickness.

Operating procedures
1. Power On/Off: Long press the OK button to turn the device on or off. Alternatively, use the "Shutdown" option in the menu. The device will automatically shut down after a set period of inactivity.
2. Baseline Calibration: Upon startup, enter the baseline calibration interface. Follow the on-screen animation instructions or skip this step. Calibration is recommended if the instrument has not been used for an extended period.
3. Measurement: Apply couplant to the surface of the material being tested. Press the instrument probe firmly against the material surface with the couplant and keep it still to measure the thickness. A symbol on the screen indicates good coupling.
4. Settings and Calibration: In the powered-on state, briefly press the OK button to enter [System Settings]. Use the directional keys to select functions such as [System Settings/Sound Speed Settings/Baseline Calibration/Shutdown].
5. Aviation Plug Connection: The aviation plug of the probe features a spring locking mechanism. Avoid forceful rotation or pulling when inserting or removing it.
Precautions
• Sound velocity is a key parameter in ultrasonic thickness measurement. Only by setting the correct sound velocity can valid thickness values be obtained. It is recommended to use a material of known thickness and the same as the object under test to set the sound velocity.
• The probe should be kept at the center of the test point, and the outer edge of the probe should not hang over the surface being measured.
• The opposite surface of the material being measured must be parallel or coaxial to the measured surface. For coarse-grained materials such as cast iron, significant scattering of ultrasonic waves may occur. If abnormal values appear, it indicates that the material is not suitable for measurement with this instrument.
• The probe is prone to scratches on rough surfaces. Minimize sliding on rough surfaces, and replace the probe promptly if it is severely worn.
• When the instrument operates for extended periods, it is recommended to perform baseline calibration to avoid the influence of external environmental factors.
• After use, clean the probe and standard test block to prevent corrosion.
