This product focuses specifically on the detection of gold K-value, with targeted optimization of the detection algorithm, achieving higher detection accuracy and faster detection speed for gold alloys. Its ±0.1% detection accuracy fully meets the daily testing needs of gold jewelry processing shops and retail stores, avoiding errors in gold K-value identification that affect product pricing. The simple one-button operation design eliminates the need for professional technical training, allowing even novice users to master the operation method quickly. The compact size and light weight make it easy to place on the counter of jewelry stores, solving the pain point of slow and inaccurate manual K-value testing for small gold trading businesses.

The device has an overall size of 160mm × 70mm × 32mm, with a net weight of 0.9kg excluding the battery. It supports detection of gold alloys from 8K to 24K, with a detection range of 33.3% to 99.99% gold content. The 2.4-inch LCD screen clearly displays the K-value, gold content percentage and detection time, and it supports one-click export of test reports. It is equipped with Bluetooth 4.2 module, supporting wireless data transmission to mobile phones or computers for record keeping. The built-in standard K-gold blocks can be used for quick calibration, and it supports automatic shutdown after 5 minutes of inactivity to save power.

This specialized detector is mainly applicable to gold jewelry processing shops, gold retail stores, gold recycling stations and individual gold traders. Typical use scenarios include rapid testing of newly processed gold jewelry, identification of the gold content of recycled gold raw materials, and price valuation of gold products in retail stores. It can also be used for on-site testing of gold products during gold trading negotiations, providing accurate data support for both buyers and sellers to reach a fair transaction.
