for insulating materials
The 2914 test cell measures dissipation factor, relative permittivity, and specific resistivity of solid insulating materials such as paper and plastic foils.
The test cell is equipped with a shielded measuring electrode which eliminates partial capacitances that influence test results.
Consists of a heatable, shielded plate capacitor (guard electrode capacitor)
Voltage: 2kV, 50/60Hz
Temperature is adjustable up to 250C
Test cell is protected by a bell jar
Safety switch only allows measurements to be carried out if bell jay is in place
