*The main, ring and opposed electrodes are sold separately.
Resistivity Chamber 15042
The resistivity chamber 15042 is a shield 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.
By combining with the accessories, the 15042 can measure the insulation resistance of not only sheet-shaped materials but also electrical components.
In addition, the LID signal terminal is mounted in consideraton of safety.
Four types of electrodes according to the JIS and ASTM standards are optionally available.
