Gold & Platinum Purity Tester GKS-3000 – 3000 g Capacity

GKS series evaluate gold (platinum) by measuring specific gravity (weight in air and weight in water).

Easy, quick, accurate, shows Gold K9 to K24 & %(percentage).

No stain, no scratches, no chemical for testing.

High capacity model
GKS-3000  Measuring range 0.01 - 3000 g 

Minimum sample weight 10 g Gold K9 - 24 & Purity 99.9% Platinum Pt600 - 1000 & Purity 99.9%

Features:

1. GKs can check purity to confirm if marked stamp on gold (platinum) is correct or not.

2. GKs are very useful to check most common type of fake gold: lower purity than marked stamp on gold (platinum).

3. Gold (platinum) which outside covered real gold, and inside with oter metal can be detected.

4. Non-gold (platinum) metals can be distinguished.

5. Can be measured scrap gold at time and show average purity.

6. Also function as a normal gram scale and Densimeter.

7. Display Gold K9-K24 & % (GKS Series: 99,9%)

8. Display Platinum/Silver:600-1000 & % (GKS Series)

Precious metals that cannot be accurately tested with GKS devices:

• Hollow items
• Items containing stones (stones must be removed before testing)
• Materials with a density close to Tungsten

Note:
For testing bars, the use of an additional device such as a BarScreenSensor is recommended.

Easy operation in 20 seconds:

1. Measure weight in air

2. Measure weight in water

3. See display for result.
