## Common Questions (FAQ)

**What is a needle detector machine?**
A needle detector machine is an industrial safety device that uses magnetic induction technology to detect broken needle tips and other ferrous metal contaminants in garments, textiles, and manufactured goods. It's essential for preventing consumer injuries and ensuring product safety compliance for export.

**What sensitivity can needle detectors achieve?**
Our industrial needle detectors can detect ferrous metal fragments as small as 0.8mm in diameter through advanced magnetic induction sensors and digital signal processing technology.

**Why do garment factories need needle detectors?**
Three critical reasons: 1) Consumer Safety—prevent injuries from broken needle fragments, 2) Brand Protection—avoid costly product recalls and reputation damage, 3) Export Compliance—meet international buyer safety standards (WRAP, Sedex, BSCI).

**How often should needle detectors be calibrated?**
At least once every 6-12 months, or as required by buyer compliance standards. Regular calibration using standard test cards (0.8mm, 1.0mm, 1.2mm) ensures detection accuracy.

**Conveyor vs. handheld needle detectors?**
Conveyor detectors are stationary machines with moving belts for high-volume automatic scanning. Handheld detectors are portable wands for pinpointing exact contaminant location. Most factories use both together.
