*The dial gauge unit (CC051011) is sold separately.
Resistivity Chamber 15702
The resistivity chamber 15702 is a shielded box which is used together with an electrometer to measure the volume resistivity and surface resistivity of sheet samples such as rubber, polymer films and clothes.
The pressure of the electrodes can be varied according to the sample used, allowing the sample to be fixed firmly regardless of its hardness. Four types of electrodes are available optionally, compliant with the JIS and ASTM standards.
In addition, the 15702 is equipped with the LID signal terminal that outputs singnals by opening or closing the shielded cover in consideraton of safety.
Also, the optional dial gauge unit (CC051011) can be used to measure the thickness of the sample for calculating volume resistivity.
