The Keysight (Agilent) 85070B High-Temperature Dielectric Probe Kit measures dielectric properties of liquids and semi-solids non-destructively across a wide frequency range and elevated temperatures. The probe immerses directly into material samples, eliminating preparation steps and special fixtures. It determines permittivity (dielectric constant), loss factor, loss tangent, and generates Cole-Cole plots for comprehensive material characterization.
Technical Specifications
• Frequency Range: 200 MHz to 20 GHz (nominal)
• Temperature Range: −40 °C to +200 °C
• Material Properties Measured: Permittivity (ε’), loss factor (ε”), loss tangent (tan δ), Cole-Cole plots
• Sample Type: Liquids and semi-solids
• Sample Preparation: Non-destructive; no preparation required
– Key Features
• Hermetic glass-to-metal seal construction resists corrosive and abrasive chemicals
• Rugged design for field and laboratory use
• Direct immersion measurement eliminates fixture complexity
• Temperature-compensated refresh calibration simplifies multi-temperature measurements
• Software generates frequency-dependent plots of ε’, ε”, tan delta, and Cole-Cole diagrams
• Tabular and graphical data output to printers and plotters
• Data export in MS-DOS ASCII or HP BASIC BDAT (HP LIF binary) formats
– Typical Applications
Dielectric characterization of coating formulations, food products, chemical liquids, and material process optimization where non-contact, real-time measurement across broad temperature and frequency ranges is required.
– Compatibility & Integration
Requires a network analyzer and controller to form a complete measurement system. Operates with MS-DOS software environment.
