1. FAST AND ACCURATE VERIFICATION: The accurate test pen features advanced thermal conductivity, can accurately distinguish carbon crystals from common artificials such as crystals or cubic zirconia
2. WITH PURPLE LIGHT: The professional version of the carbon crystal tester is equipped with built in purple light, which can reveal the fluorescence of carbon crystals and is an important key for verifying authenticity
3. FLUORESCENCE DETECTION: Different materials exhibit different responses under purple light, so this function can be used for more in depth assessment
4. EASY TO OPERATE: The carbon crystal tester features real time feedback with LED lights and sound. After preheating for 25 seconds, hold the conductive panel at the top with your finger and tilt the vertical carbon crystal 90 degrees. When a real carbon crystal is detected, the red LED will flash and the buzzer will sound
5. TRUSTED PLASTIC: Professional carbon crystal tester is made of excellent plastic material, water proof, light weight, and a good insulator
