The 12704A resistivity chamber is a shield box which is used together with an electrometer to measure the volume resistivity and surface resistivity of sheet, filmy and platy samples. Samples can be set very easily, and it is provided with a volume/surface resistivity measurement switch and an applied voltage ON/OFF switch which turns on and off according to opening and closing of the cover.
Adhesion with the sample is excellent because all electrodes use conductive rubber.
