Isotropic (Standard)
All-round testing of bulk samples
Our foundational and powerful Isotropic Measurement Module allows the Hot Disk® Instrument user to measure the Thermal Conductivity, Thermal Diffusivity, Thermal Effusivity and Specific Heat Capacity of any isotropic bulk sample, whether a solid, liquid, granule, powder, paste, gel, foam or insulator, with high accuracy. The Hot Disk® sensor is clamped between two identical sample pieces. Sample thickness ranges from several centimeters down to sub-millimeter format.

Anisotropic (Add‑on)
Testing samples with direction dependent properties
With our add-on Anisotropic Measurement Module, the Hot Disk® Instrument user can measure the direction dependent Thermal Conductivity, Thermal Diffusivity, and Thermal Effusivity of an anisotropic sample, whether a crystalline or polycrystalline material, laminate, fiber material, adhesive, film stack, foil stack, insulator, etc. Samples with 2D or 3D anisotropy, i.e. of an uniaxial or biaxial medium, can be analyzed.
Works with Hot Disk® Instruments:
- * Can handle samples with 3D anisotropy

Slab (Add‑on)
Testing highly thermal conductive slab or sheet samples
With our add-on Slab Measurement Module, the Hot Disk® Instrument user can accurately measure the in-plane Thermal Conductivity, Thermal Diffusivity, and Thermal Effusivity of a highly thermal conductive slab or sheet sample. The slab or sheet can be a metal plate, graphite sheet or laminate, semiconductor wafer, silicone film, metal foil, etc. Sample thickness ranges from several millimeters down to micrometers.

Thin Film (Add‑on)
Testing thermal insulating thin film samples
With our add-on Thin Film Measurement Module, the Hot Disk® Instrument user can easily measure the through-plane Thermal Conductivity of a thermal insulating film or coating, with thickness in the micrometer range. The film can be a plastic, paper, flexible glass etc., while the coating can be a sprayed polymer, sputtered dielectric, spin-coated ceramic, etc.

Low-Density / Highly-Insulating (Add‑on)
Testing the lightest and most insulating samples
With our add-on Low-Density / Highly-Insulating Measurement Module, the Hot Disk® Instrument user can confidently measure the Thermal Conductivity of ultra-low thermal conducting materials such as aerogels. Applying special routines to carefully correct for the heat loss via the sensor leads during a measurement, samples with Thermal Conductivity as low as 0.01 W/mK can be determined with high accuracy.

One-Dimensional (Add‑on)
Testing rod-like samples
With our add-on One-Dimensional Measurement Module, the Hot Disk® Instrument user can measure the through-plane Thermal Conductivity, Thermal Diffusivity, and Thermal Effusivity of a rod-like sample, with width down to 1.5 millimeters and length down to 4 millimeters. This module comes in handy when sample amounts are limited, for example regarding precious metal bars or ingots, graphite pellets, and spark-plasma-sintered materials.

Structural Probe (Add‑on)
Identify defects and structural changes inside samples and components
With our add-on Structural Probe Measurement Module, the Hot Disk® Instrument user can measure the Thermal Conductivity as a function of depth into relevant samples, ranging from sub-millimeter up to plural centimeter formats. This unique capability offers a powerful tool for QC testing, as homogeneity, defect detection or analysis of inhomogeneous substances, inside a sample or component, can thus be tested non-destructively. Examples of components include rubber tires, brake pads, and graphite-epoxy structures.

Single-Sided Testing (Add‑on)
Rapid production line QC testing
With our add-on Single-Sided Testing Measurement Module, the Hot Disk® Instrument user can measure the Thermal Conductivity, Thermal Diffusivity, Thermal Effusivity, and Specific Heat Capacity with high precision, while not being required to clamp the Hot Disk® sensor between two identical sample pieces. Instead the Hot Disk® sensor, together with a thermal insulating background support, is placed on the surface of a single sample piece or component. This allows for quick QC measurements of adequate precision at a production line assembly.

Specific Heat Capacity (Add‑on)
Testing Cp of complex samples and batteries
With our add-on Specific Heat Capacity Measurement Module, the Hot Disk® Instrument user can directly measure the Specific Heat Capacity (Cp) of complex samples and components with high accuracy. These include solids with non-flat surfaces, components with largely varying sizes, liquids, and pastes. Further examples of components are batteries (button-, cylindrical-, prismatic-, and pouch-cell batteries). Precise measurements are conducted using our dedicated Cp cells (metal containers with a Hot Disk® sensor attached). Measurements without a Cp cell is also possible for bulk samples with high thermal conductivity (>5 W/mK)
Works with Hot Disk® Instruments:
- * Only measurements without a Cp cell.
