3. Calibrate KGA with known piece of 18K, set meter to center of white zone.

4. Test items

5. Replace Cap to Wand and Turn KGA off when done.

Changing the battery:

2. Remove protective rubber cover.

3. Remove the two Phillips screws.

4. Gently pull KGA apart

KEE Gold Analyzer Instructions



  • Plug red lead wire into either "slot E or slot G" on the meter.
  • Plug black lead wire into "slot F" on meter.
  • Turn on meter at location "B".
  • Calilbrate meter "C" to center of 18k zone, while testing a known peice of 18k
  • Polish gold to be tested with tip from testing probe "P".
  • Place gold on integrated test plate "D" or clip with allligator tip "L".
  • Place contact tip of pen "Q" on gold at (3) three different areas,
    concentrating on a "high wear area".
  • If you get different readings each time, use the polishing tip or file and retest.

Gold Karat and Alloys

Because gold can come in so many forms, there is a grading system designed to alert the goldsmith and the buyer how valuable the item is, and what it is made of. Because pure gold is extremely soft, other metals are mixed with the gold to make the piece more durable, less expensive, and to alter it's color.

  • 24K 100% pure gold.
    No other metal has been mixed
  • 18K 75% pure gold.
    Contains 18 parts gold and 6 parts of one or more additional metals.
  • 14K 58.3% pure gold.
    Contains 14 parts gold and 10 parts of one or more additional metals.
  • 12K 50% gold.
    Contains 12 parts gold and 12 parts of one or more additional metals.
  • 10K 41.7% gold.
    Contains 10 parts gold and 14 parts of one or additional metals.
    Minimum karat that can be called "gold" in the United States.

When metals are added to the gold the result is an alloy, a blended mixture of metals that will read somewhat differently on the meter scale. This does not mean that a 14k mixed with nickel is worth more or less than 14k mixed with copper. It simply means they will read differently by a small margin. They will both contain the same amount of gold, "58.3%".

It is also possible that a 14k piece reading at the low end of the 14k scale will read very close to or the same as a 10k piece reading at the high end of the 10k scale. This is because the alloy in the 14k reads more resistance than the alloy in the 10k. this is rare but possible.

Frequently asked questions

How do I calibrate my meter?

Calibrating your meter is easy. All you need to do is test a piece of known 18k gold, and while testing, turn the adjusting knob until the meter needle is centered in the white 18k zone.

Why won’t my meter calibrate to 18k anymore?
 When your meter will not calibrate to 18k, it normally means the battery needs to be replaced. Please follow the directions for “replacing battery” in the Q&A section. It can also mean the probe needs replaced this will depend on usage and probe care. Always replace battery first. (Note: If the probe is left with cap off, this will greatly reduce the life of the probe.)

How do I change the battery?
 First remove the black rubber protective case from the meter body. Remove the 2 phillips head screws from the back of the case. Replace the single AA battery and reassemble. (Note: because of the unique operating system of this meter, use only new, fully charged batteries!)

How Long will my testing probe last?
This all depends on use. We expect the test probe to last several months. If the meter is only used occasionally, the life span will be increased. Leaving the cap loose or off will greatly reduce the life of the probe.

Why is this meter analog instead of digital?
Although digital is the latest technology, it is not always suitable for all conditions and jobs. Because of the delicate nature and variables of testing gold, we at KEE Gold decided that a quality analog meter movement is a better fit for this job. Analog movements show all the different variables that can be found testing gold and gold plate. This gives the user an easy to see needle, that can become very quick to read and understand.
