ST 13 full featured PN type identifier operation video

The ST-3 type conductivity type identification instrument is an instrument for identifying a semiconductor conductivity type (PN type) using a thermoelectric potential principle and a rectification method.
Complete set of instruments: The instrument consists of a main unit and two sets of probes. The conductivity type P or N is displayed by a digital tube. The probe is used by both cold and hot.
Advantage characteristics:
In the thermoelectric potential method, the thermal probe has a constant temperature adjustable function to meet the needs of a wide range of low resistivity conductivity type tests! Both cold and hot probes are plug-in for easy replacement.
In the rectification method, the apparatus of the semiconductor conductivity type is identified by the principle of the rectification method, and the function of testing the re-doping is also provided.
The key components of the instrument adopt special-purpose integrated circuit and adopt high-quality patch technology. The instrument has the characteristics of wide identification range, high sensitivity, good stability and convenient use.
It is suitable for semiconductor material manufacturers, semiconductor device factories, research institutes, universities and other places to test the conductivity type (PN type) of a wide range of low-resistance semiconductor materials.
