Product Introduction
The four terminal electrode measuring instrument 4P-1 can test the resistance of conductive materials using the four terminal method (Kelvin) according to the DIN EN ISO 3915 standard.
major function
The four terminal electrode measuring instrument 4P-1 is specially developed for testing the surface resistance of conductive material samples through the four terminal method.
The special tool contact structure design of the electrode makes the connection of the test sample simple and firm.
The horizontally movable sample ensures that different positions of the sample can be tested without touching it again.
Connecting the testing instruments Milli-TO 3 and TO 3 makes precise measurements in the low ohmic domain possible.
The sample clip can also be connected to a megohmmeter to test high ohmic resistance
