UNI-T UT387E – Professional Detector of Wires and Structural Components in the Wall
The UNI-T UT387E is an intelligent detector for wires, metal and structural elementslocated in walls. It is an indispensable tool for electricians, fitters, builders and DIYers who want to avoid accidentally drilling the installation or damaging the load-bearing elements. The UT387E combines detection precision with simple, intuitive operation and an easy-to-read LCD display.
Detection of wires, metal and wooden components
The UT387E detector can effectively detect:
- live (AC) cables
- metal components (iron, steel, copper, etc.)
- wooden structural elements (e.g. beams, frames)
Thanks to digital signal processing (DSP), the device analyzes the data in real time and presents a precise result on the screen. Built-in LED indicators and audio and graphic signals help to accurately locate the detected object.


Easy-to-read screen and intuitive signage
The UT387E is equipped with a backlit LCD display that shows the type of object detected and its depth in real time (for metal and wood). The screen is supported by built-in LED signaling and an audible alarm, which makes it easy to precisely locate the installation in the wall, even without visual contact.
Accuracy and safety
Thanks to the technology used, the UT387E allows you to detect:
- live wires at a depth of up to 50 mm,
- ferrous metal – up to 100 mm,
- non-ferrous metal (e.g. copper, aluminium) – up to 80 mm,
- wooden elements – up to 20 mm.
These are sufficient parameters to safely plan drilling, forging or other assembly work in most typical walls (plaster, concrete, brick, wood).
