ST-30C type sensitivity level can be adjusted handheld needle detector , this model is our latest product launch of a hand-held needle detector has low sensitivity, a key regulatory function, the detection sensitivity is extremely high. Particularly suitable for metal buttons, metal zippers ferromagnetic check job ( over needle ) ; demanding for testing children's clothing, underwear applies. Which handheld portable needle detector using magnetic induction principle, be able to effectively and accurately detect the needle and other iron items specific location . For the thin parts and is ideal for testing small items . For large needle detector , this hand-held needle detector can help you find exactly small ferromagnetic metal needle or the exact location .

 
Main features :
Has a low sensitivity a key regulatory function , sound and light alarm simultaneously ;
Made of high quality carbon fiber anti-static conductive plastic production carton ;
Easy to operate , lightweight and easy to carry, high sensitivity detector ;
The use of imported high-end digital chip , performance is more stable and durable ;
Can accurately identify the needle ( metal ) location ;
Continuous long-term work , no heat , no overload ;
Supply voltage less than 6V will produce more than a continuous chirping sound , it means lack of electricity should be replaced.

Use Scope :
1 .  can be knitting, clothing , socks , clothing , leather, shoes and so thin, small pieces of products for breakage detection, can quickly find the right iron needles falling off decapitation .
2 .  can be used for hardware buttons and other apparel accessories for inspection of ferromagnetic impurities , high sensitivity is equivalent to the so-called 8-10 grade, low sensitivity level equivalent to 5-8 Needle ( high-sensitivity detection of 0.5 ~ 0.8mm suitable for textile inspection , low- sensitivity detection for applications requiring a low 0.9-1.2mm metal zippers and buttons shoe , leather, nail class detection probe used ) .
3 . the pharmaceutical , food , chemical raw materials detection of ferromagnetic materials .
4 . can be of wood , walls, tables inside the nail , steel , pipe inspection presence .
5 .  can be on the human body , animals and other work-related injuries , cuts, crushing, and other parts for inspections whether its internal iron infiltrated the harmful substance .
6 . can be used to inspect the border customs posts , public servants being seized rapid search of hidden weapon .
