Product Overview
The Qili UT800 ultrasonic thickness gauge utilizes the pulse reflection ultrasonic principle, specifically designed for measuring 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. By simply placing the probe on one side of the measured object, it enables rapid thickness measurement. Suitable for multiple fields including industrial manufacturing and quality inspection, it serves as a reliable partner for thickness measurement.

Application Field
Industrial manufacturing, quality inspection
Compliant with standards
JJF 1126-2004 Calibration Specification for Ultrasonic Thickness Gauges
Operating Steps
1. Power On/Off: To power on, press and hold the OK button to enter the baseline calibration interface; to power off, press and hold the OK button or click "Shutdown" in the menu bar. The instrument will automatically shut down after reaching the set time without operation.
2. Baseline Calibration: After entering the "Baseline Calibration" interface, follow the calibration animation prompts or skip. It is recommended to calibrate when the instrument has not been used for an extended period.
3. Measurement: Apply couplant to the surface of the material to be measured, press the instrument probe firmly against the material surface with couplant and keep it still to measure the thickness. When the probe is properly coupled, the coupling indicator on the right side of the screen will remain steady, accompanied by a buzzer prompt.
4. Settings and Calibration: In the powered-on state, briefly press the OK button to enter [System Settings]. Use the up and down arrow keys to switch between [System Settings / Sound Velocity Settings / Baseline Calibration / Shutdown], and briefly press the OK button to select.
5. Aviation Plug Connection: Insert or remove the aviation plug of the probe. The aviation plug has a spring limit; avoid forceful rotation, pulling, or similar operations.
Precautions
1. 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 with a known thickness and the same as the object to be measured to set the sound velocity.
2. The probe should be kept at the center of the point to be measured, and the periphery of the probe should not be suspended outside the surface to be measured.
3. The other surface of the measured material must be parallel or coaxial with the measured surface. For coarse-grained materials such as cast iron, which cause significant scattering of ultrasonic waves, abnormal values indicate that this material is not suitable for measurement with this instrument.
4. The probe is easily scratched on rough surfaces. Minimize sliding on rough surfaces, and replace the probe promptly if it is severely worn.
5. When the instrument operates for an extended period, it is recommended to perform baseline calibration to avoid the influence of external environmental factors on the instrument.
6. After use, clean the probe and the standard test block to prevent corrosion of the probe and the standard test block.
