Key Features UNI-T UT387C Stud Sensor Wall Detector

• Three Detection Modes — Wood Stud mode (up to 38 mm), Deep Metal/Rebar mode (up to 76 mm), and AC Live Wire mode for complete wall scanning coverage.
• AC Wire Detection Safety — The device identifies live 50/60 Hz AC electrical wires behind walls before drilling, preventing dangerous electrical accidents on every job site.
• LED Bar + Audio Alert — A multi-segment LED indicator bar and audible beeping tone guide you to the exact center of any stud or object, removing all guesswork.
• Auto-Calibration Technology — The UT387C calibrates itself automatically against the wall surface, so every scan starts accurate without manual adjustment.
• Deep Scan Capability — Metal detection reaches 76 mm depth, making it effective on concrete walls, timber-framed structures, and thick plasterboard common in Bangladeshi construction.
• Ergonomic One-Hand Design — The compact, lightweight body fits comfortably in one hand, reducing user fatigue during extended scanning sessions on large walls UNI-T UT387C Stud Sensor Wall Detector
• Clear LCD Display — The backlit LCD screen shows detection mode status and signal strength in real time, even in low-light environments.
• Battery Indicator — A low-battery warning prevents unexpected shutdowns mid-project, ensuring reliability throughout the workday.

 

Frequently Asked Questions (FAQ) UNI-T UT387C Stud Sensor Wall Detector

Q1: What materials can the UNI-T UT387C detect behind walls?

The UT387C detects three types of hidden objects. It finds wood studs and joists in wood-framed walls up to 38 mm deep. It locates metal objects including steel pipes, rebar, and conduits up to 76 mm deep. It also identifies live AC electrical wires carrying 50 Hz or 60 Hz current up to 76 mm behind the wall surface UNI-T UT387C Stud Sensor Wall Detector

Q2: Does the UT387C work on concrete walls common in Bangladesh?

Yes. The deep metal and rebar detection mode specifically targets reinforced concrete construction. In Bangladesh, where RC-frame buildings dominate urban housing, the UT387C locates rebar positions accurately to depths of 76 mm, making it highly relevant for local construction conditions UNI-T UT387C Stud Sensor Wall Detector

Q3: How does the auto-calibration feature work?

When you press the detection mode button, the UT387C scans the wall surface at the starting position and sets that as the baseline reading. Subsequently, as you slide the device across the wall, it compares incoming readings against the baseline and triggers the LED and beeper when it detects a significant change indicating a stud or object beneath UNI-T UT387C Stud Sensor Wall Detector

Q4: Can a non-professional DIY user operate the UT387C?

Absolutely. The auto-calibration removes the need for manual setup. The LED bar indicator and audio beep provide clear, intuitive feedback that requires no technical training to interpret. Most users achieve reliable results after just one or two practice scans on a test area.

Q5: What battery does the UT387C use and how long does it last?

The UT387C uses one standard 9V battery (6F22 or 6LR61 type), widely available in Bangladesh. Battery life depends on usage frequency. The LCD screen displays a low-battery warning icon before the battery dies completely, giving you time to replace it before your next project.

Q6: Is the UNI-T UT387C suitable for tile and brick walls?

The UT387C works best on drywall, plywood, plaster, and similar smooth surfaces. On tile and brick walls, results vary depending on material density and surface irregularity. However, the metal and AC wire detection modes remain functional through these materials when the target is within the detection depth range.

Q7: What is the warranty on the UT387C from ASTZBD?

ASTZBD provides a 1-year manufacturer warranty on every UNI-T UT387C unit sold through the platform. The warranty covers manufacturing defects and functional failures under normal use conditions. ASTZBD also provides dedicated after-sales support throughout the warranty period. UNI-T UT387C Stud Sensor Wall Detector

 

Applications UNI-T UT387C Stud Sensor Wall Detector

Construction & Civil Engineering

Contractors use the UT387C to locate rebar and metal conduits inside reinforced concrete before coring or drilling. Moreover, civil engineers map structural members in load-bearing walls to plan safe anchor positions UNI-T UT387C Stud Sensor Wall Detector

Electrical Installation

Licensed electricians scan walls before chasing cable routes to avoid existing live circuits. The AC wire detection mode provides an essential safety check before every cut.

Interior Design & Furniture Mounting

Interior designers and carpenters locate wood studs to mount heavy shelving units, TV brackets, cabinets, and artwork securely. In addition, the wood mode confirms stud spacing for even load distribution.
