Specification:
Material: ABS

Power supply: 1 X DO 9V battery (not included)
Product size: 160*40*22mm

Maintenance and repair:
1. The instrument is very sensitive to the probe, so you must take special care to protect it, and put it on the sheath when not in use.
2. The prepared indicator is very dark, indicating that the battery will be used up, and the battery should be replaced in time.
3. Please remove the battery if the instrument is not used for a long time.
4. For accurate detection, it is recommended to calibrate once a year.

Tip:
When detecting a diamond, the indicator light shows more than 9 bars and makes a sound to indicate that it is a genuine product.
When the jade is detected, if the indicator shows more than 7 bars, it means it is genuine.

Note:
Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures. Thank you!
Please allow 1-3cm measuring deviation due to manual measurement.
