Located in room A2550, The Novocontrol Broadband Dielectric Spectrometer (BDS) model Concept 40 system features high performance dielectric, conductivity, electrochemical, impedance and gain phase measurements in the frequency domain. The permittivity, conductivity and impedance of nearly all materials or components including special functions can be measured broadband and over a wide temperature range without changing sample geometry or sample cells. It have the Alpha-A measurement systemm, Quatro Cryosystem with BDS 1100 chamber and BDS 1200 standard sample cell electrode assembly. Temperature range −160 °C ... 400 °C Temperature ramps from 0.01 °C/min .. 20 °C/min 0.01 °C temperature stability Low nitrogen consumption, typically 1 l/hr at T> −100 °C Temperature overshooting after setpoint step typically < 0.2 °C Stabilization times typically < 8 minutes (for 0.1 °C stability) Automatic adaptation of controller parameters (self tune) 4 loop microprocessor with 24 bit ADC and GPIB communication port Vacuum-isolated cryostat and nitrogen line
