Key benefits — why you need this detector Rapidly locate tiny ferromagnetic metal needles and fragments to reduce product defects, prevent customer injury and avoid costly recalls. Simple, one-button adjustment and clear sound-and-light alarms let operators find needles quickly and confidently, even on small or thin parts. Lightweight, portable and designed for continuous use without overheating or overloading, so you can use it across multiple production or inspection points. Main features High sensitivity detection: precisely finds small ferromagnetic metal needles and accurately indicates their position. One-button adjustment: fast setup and operation — ideal for use by production staff or quality inspectors with minimal training. Sound and light alarm: simultaneous audible and visual alerts make locating detected metal quick and unambiguous. Stable, durable performance: built with an imported high-end digital chip for consistent, reliable operation over time. Portable, hand-held design: compact and easy to carry for spot checks, line inspections or field use. Magnetic induction principle: detects the specific iron position of needles and other ferromagnetic parts using magnetic induction for accurate localization. Continuous operation: engineered to run for long periods without overheating or overloading. Compatibility and suitability Best suited for ferromagnetic metals (e.g., iron/steel needles and fragments). Designed for thin parts and small items where precise positioning is required. Works in a variety of environments and inspection scenarios where handheld, high-sensitivity detection is needed. Practical applications (3 typical scenarios) Textile and garment inspection: quickly find broken or lost sewing needles in finished garments, linings and trims before shipping. Small parts quality control: locate tiny steel fragments in shoes, leather goods, toys or assembled components during production or final inspection. Workshop and field checks: handheld scanning of thin panels, small assemblies or finished products to confirm absence of ferromagnetic hazards. What sets this detector apart Combines a highly sensitive detector and imported digital chip for long-term stability and repeatable results. One-button adjustment and dual sound/light alarms simplify use and reduce human error. Portable, lightweight construction makes it practical for on-line checks, spot inspections and off-site use without risk of overheating or overloading. What to expect in use Quick identification of the iron-containing position of needles and fragments. Easy handling for small or thin items thanks to its sensitive, hand-held detection head. Reliable alerts (audio + visual) for immediate localization and removal. Note: This product is intended for detecting ferromagnetic metal needles and fragments using magnetic induction; follow normal safety and inspection procedures when integrating into production or quality workflows.
