UNI-T UT387E – Professional detector of wires and structural elements in the wall
UNI-T UT387E is a smart detector of wires, metal, and structural elements located in walls. It is an indispensable tool for electricians, installers, builders, and DIY enthusiasts who want to avoid accidentally drilling into installations or damaging load-bearing elements. The UT387E model combines detection precision with simple, intuitive operation and a clear LCD display.
Detection of wires, metal, and wooden structural elements
The UT387E detector allows for effective detection of:
- live wires (AC)
- metal elements (iron, steel, copper, etc.)
- wooden structural elements (e.g., beams, frames)
Thanks to digital signal processing (DSP), the device analyzes data in real-time and presents an accurate result on the screen. Built-in LED indicators and sound and graphic signals help to precisely locate the detected object.


Readable screen and intuitive markings
The UT387E model is equipped with a backlit LCD display, which shows in real time the type of detected object and its depth (for metal and wood). The screen is supported by a built-in LED signaling and sound alarm, which makes it easier to precisely locate installations in the wall, even without visual contact.
Accuracy and safety of operation
Thanks to the applied technology, the UT387E allows for the detection of:
- live wires at a depth of up to 50 mm,
- ferrous metal – up to 100 mm,
- non-ferrous metal (e.g. copper, aluminum) – up to 80 mm,
- wooden elements – up to 20 mm.
These are sufficient parameters to safely plan drilling, chiseling, or other installation work in most typical walls (plaster, concrete, brick, wood).
