Connectors: 4x individually shielded electrical feedthroughs with BNC plugs
1x miniature thermocouple plug
2x 6 mm stainless steel tubes for gas supply
Maximum Sample diameter: 20 mm
Maximum Sample thickness: ca. 20 mm
Maximal temperature: 550 °C
Short circuit impedance: (set-up resistance with 2 m coaxial BNC cables at room temp)
Two wire configuration: ca. 2 Ω
Four wire configuration: ca. 5 · 10-2 Ω
Temperature Measurement withthermocouple Type S (optional Type K)
Leak rate is typically: 5 · 10-4 mbar · l · s–1
Open circuit impedance measured at room temperature gives ca. 1 · 1013 Ω and ca. 1 · 10-12 F for the resistive and the capacitive part respectively. The inductive part in the impedance spectra, if visible, generally depends on the connected measurement BNC cables between the impedance analyzer and the Plug&Probe.
The Plug&Probe Green consists of a metal flange in a blue cover and a removable glass test rod with an interior glass test interface using platinum wiring. All parts are spring mounted to prevent breaking and ensures a stable electrical contact between the electrodes and the specimen. The heated part of the Plug&Probe Green only consist of glass and platinum to ensure no outgassing and to prevent any reactions between specimen and sample holder. In case you cannot use platinum in your experiment, you may want to change to another test station with different contact materials. In case you want to contact other sample geometries or specimens with more electrodes or you need information regarding other sample holders please contact your local sales person or Huber Scientific.
