Uni-T UT387S Wall-Mounted Scanner

The Uni-T UT387S wall-mounted scanner is a professional-grade detection device engineered to identify hidden objects behind wall surfaces. This versatile tool integrates multiple functionalities, including the detection of ferrous metals up to 100 mm, non-ferrous metals up to 80 mm, wooden studs up to 38 mm, and live AC electrical wiring up to 40 mm. Beyond its primary scanning capabilities, the device incorporates a wood moisture meter with a range of 6% to 40% and a built-in laser rangefinder capable of measuring distances up to 40 meters. Featuring a 2.4-inch color display, voice guidance, and a rechargeable Li-ion battery, it provides a comprehensive solution for construction, electrical, and renovation tasks.

Advantages

The primary advantage of the Uni-T UT387S is its multi-functional design, which reduces the need for carrying multiple separate tools. By accurately locating structural elements and electrical conduits, it significantly minimizes the risk of accidental damage during drilling or wall mounting, thereby enhancing workplace safety and preventing costly repairs. The inclusion of a laser rangefinder and a moisture sensor adds significant value for carpentry and interior finishing projects. The intuitive interface, combined with voice prompts and a high-contrast color screen, ensures that users can operate the device efficiently even in challenging lighting conditions or complex environments.

Suitable for

• Locating metal pipes and structural steel behind drywall
• Detecting wooden studs for secure shelf or cabinet installation
• Identifying live electrical wires to prevent drilling accidents
• Measuring wood moisture levels for carpentry and flooring projects
• Calculating room dimensions and distances using the integrated laser rangefinder

When it may not be suitable

This device may not be suitable for scanning through extremely thick concrete, dense masonry, or metal-clad walls, as these materials can significantly interfere with sensor accuracy. It is also not intended for industrial-grade geological surveying or deep-earth scanning applications.

How to use

To begin, power on the device and select the appropriate detection mode based on the material you are searching for. Place the scanner flat against the wall surface and move it slowly across the area of interest. The device will provide visual feedback on the color screen and audible voice prompts when an object is detected. For the laser rangefinder and moisture measurement functions, switch to the respective mode and follow the on-screen instructions to obtain precise readings. Ensure the surface is clean and free of debris to maintain optimal sensor contact.

What to consider before purchase

• Verify that the detection depths meet the requirements of your specific wall construction type.
• Ensure the device is charged using the provided USB cable before initial use.
• Consider the environment; the device is designed for standard residential and commercial wall structures.
• Check that the measurement units align with your regional standards.

Usage recommendations: Always calibrate the device according to the user manual before starting a new scanning session to ensure maximum accuracy. Avoid wearing metal jewelry or touching the wall surface near the scanner during operation to prevent interference with the sensor readings.
