Import 500x 2.0megapixels Usb Digital Microscope Kln — Buy in Bulk from Supplier in China

The KLN-series USB digital microscope offers a magnification range of 50x to 500x through a 2.0 megapixel colour CMOS sensor, outputting via USB 2.0 to Windows-based computers. Still image resolution scales from 320 x 240 up to 1600 x 1200 pixels in JPEG format, while video records as AVI or WMV at 640 x 480 and 30 frames per second. Manual focus adjustment spans 0mm to 80mm, and eight white LEDs with manual brightness control provide oblique illumination for reflective or translucent specimens. The unit draws power entirely from the USB port, eliminating external adapters. Kalinu Technology Co., Ltd. manufactures this instrument in Ningbo, Zhejiang province.

The 2.0 megapixel sensor delivers a native resolution sufficient for screen display and basic documentation, though it falls below modern 5MP or 8MP inspection cameras for fine-detail metrology. The 30fps frame rate at VGA resolution supports real-time focusing and manipulation without significant lag on USB 2.0 bandwidth. Manual white balance and auto exposure compensation are provided; professional applications may require calibrated colour reference targets to assess accuracy. The 98mm length and 30mm radius cylindrical body fit the supplied stand with holder, allowing hands-free positioning over circuit boards, textiles, or biological samples. Standard industry practice for USB microscopes in this segment includes software with measurement calibration, though the exact feature set should be confirmed with the supplier.

Target buyers include PCB assembly houses, textile quality labs, educational institutions, and collectors requiring macroscopic examination of stamps, coins, or jewellery. The Windows-only software support, including Win7 32-bit and 64-bit, should be verified against current operating systems if deployment on Windows 10 or 11 is intended. The 55-inch (approximately 1.4 metre) cable allows flexible positioning between microscope and computer. Packaging ships 20 units per carton with gross weight 7.2kg and carton dimensions 49 x 33 x 35cm. Individual unit gross weight is 320g with retail box size 20 x 13 x 9cm. Incoterms, lead time, and minimum order quantities are not stated and require direct negotiation with Kalinu Technology Co., Ltd.

Kalinu Technology Co., Ltd. is registered at 252 Hujiata, Xiaogang, Beilun, Ningbo, Zhejiang, 31580, China. The supplier holds imported-tier status with harbour trust level on the platform. Response metrics show 0.00% response rate and zero average response hours, indicating no recorded inquiry activity or unavailable tracking. The address places the company in Ningbo's Beilun district, an industrial zone with established manufacturing and port access, though the profile does not confirm owned factory versus trading office.

No establishment year, registered capital, employee count, factory floor area, or annual revenue figures are provided. The listing does not cite ISO 9001, ISO 13485 (medical devices), or optical instrument-specific accreditations. Buyers should request a business licence, any existing quality system certificates, and evidence of in-house assembly or original design manufacturing (ODM/OEM capability). The KLN model designation appears to be a Kalinu house brand, but trademark registration should be verified if exclusivity is sought. Direct communication with the supplier is essential to confirm production capacity, sample availability, and whether engineering support is offered for custom software or hardware modifications.
