Conductivity Type Tester :HS-HCTT
       It is strictly designed according to the requirements of the hot-probe thermal EMF conductivity type test  in standard ASTM F42: Standard Test Methods for Conductivity Type of Extrinsic Semiconductor Materials.
       A temperature controlling heating element is installed inside the hot probe so that the hot probe is heated automatically and its temperature is maintained in the range 40-60℃. The sign of thermal emf generated between the two probes is amplified by the integrated computing amplifier, the result is displayed on the liquid crystal display in the form of letter N or P directly.
