เครื่องวัดความต้านทานบนผิววัสดุ Surface Resistance Tester BK485

Features:

This tester measures the surface resistance of the object and the surface resistance. It is convenient to repeatedly test conductivity,
electrostatic dissipation and insulation. This tester is adopted ASTM Standard D 257 Barcode Sensing Method. Using a high speed
OP-AMP integrated circuit, the classification is done automatically. The integrated circuit is linear, in Logarithm (10% per unit average). The up-conversion point is 1/2 decimal.
