Diamond Tester Pen - High Accuracy Jewelry Professional Selector Kit for Novice and Expert

Diamond Tester Pen with High Accuracy, Environmental Protection 9V Battery, Jewelry Diamond Tester features. When testing a stone, the diamond indicator will display if it is a real diamond (green light) and give a metal alert (continuous buzzing sound) if the user accidentally touches metal instead of the stone. The tester has a large/small switch for testing diamonds ranging from 1 to 8 points, an LCD display, and LED indicator. It is powered by a DC 9V battery.

To test a diamond, turn on the switch and ensure only one light is lit up on the scale. Wait for the probe to heat up until the Lamp on ready OK. Turn on the lights corresponding to the indoor temperature and diamond weight. If unsure, set four lights to be lit up on the scale. To start testing, use the diamond discriminator probe at a 90-degree angle with the object to be measured and observe the indicator light change. Apply some pressure to ensure full contact. If unsuccessful, repeat the process.

For result analysis using the Molo Diamond Tester Pen, if the lights are 9 or more with sound, it is a true diamond. If lights show 7 or 8, it is a true crystal. Lights indicating 6 or 7 correspond to true jade, and 4 or 5 to glass. It is important not to test metal and avoid wearing gloves. In a low-temperature environment, the battery discharge may weaken, so it is recommended to keep the battery temperature above 10 degrees Celsius.
