Diamond test pen

Specification: 16.5 * 4 cm

 Is dedicated to the identification and imitation diamond designed a kind of instrument, precious stones in the highest thermal conductivity for diamond, diamond at room temperature of the thermal conductivity from Ⅰ type 100 w / (m °C) changes to Ⅱ type a 2600 w / (m °C) of the seeds for corundum, its 40 w / (m °C). Recent synthetic moissanite its thermal conductivity is high, second only to the diamond in the instrument next also have reaction. Thermal conductivity meter is using diamond this thermal properties to identify the diamond and in addition to synthetic moissanite outside of the diamond imitations. Operation more convenient, results are intuitive. The typical diamond thermal conductivity meter by measuring head and control box of composition, measuring head metal tip for electrical heating, when heating metal tip penetration diamond surface, temperature drops obviously, electric sensing will be Beeping.

Thermal conductivity meter is according to the diamond thermal conductivity performance and the design and manufacture of specialized is used to identify the diamond true and false of an electronic instrument.

1, control needle

2, 3 color display lamp

3, power light

4, prepare light

5, power switch/adjustment knob

6, battery cover Technical

characteristics:

1, pocket with then handheld.

2, nondestructive testing, easy operation accurate.

3, working power supply: DC9V battery.

4, physical size: 160 * 40 * 22 mm weight: about 110 g

Operation method:

1, open the power, the power indicator light, instrument began to preheating and a few seconds later the instrument can be used. 2, will be measuring naked drill into the support tray appropriate concave hole, and its mesa up. Already inlayer need not put tray hole, and hand the can.

3, according to measured true and false diamond weight and measurement site temperature adjustable light several light emitting diode.

4, take down probe sheath, handheld instrument, right index finger touch instrument back cover conductive plate; Make probe vertically

The work effect : identify true diamond of a kind of electronic instruments

Notes:Precision electronic instrument please don't try to open in addition to the battery cover outside of the anything! In order to avoid damage the instrument!
