Four terminal electrode measuring instrument VE-D 991

　　Product Introduction:

　　The four terminal electrode measuring instrument VE-D 991 can test the body resistance of conductive and anti-static material samples using the four terminal method (Kelvin) according to the ASTM D 991 standard.

　　Main functions:

　　The four terminal electrode measuring instrument VE-D 991 is specially developed for testing the body resistance of conductive and anti-static samples through the four terminal method.

　　The electrode structure follows the standard ASTM D 991.

　　The device structure allows the cross-sectional area of the testing cable to be between 0.1 mm2 and 100 mm2.

　　The special structural design of the electrode makes the connection of the test sample simple and firm.

　　Connecting the testing instruments Milli-TO 3 and TO 3 makes precise measurements in the low ohmic domain possible.
