Instruments & Auxiliaries

Instruments

A wide range of Hot Disk® instrument models is available for testing and measuring Thermal Conductivity, Thermal Diffusivity, Thermal Effusivity and Specific Heat Capacity following ISO 22007-2. While typically generous of measurement spectrum, our top-of-the-line instruments are unique in monitoring ultra-short transient temperature readings, thereby tackling sub-millimeter-thick samples and highly-thermal conducting materials, beyond 1800 W/m/K. A further unique feature of our instrumentation is that it requires no external calibration. Our clients can confidently continue its employ, without worrying over the inconvenience of being obliged to return their instruments for re-calibration at regular intervals. Each Hot Disk® instrument includes two LEMO connector ports: one for the relevant Hot Disk® sensor, and one for the optional PT100 ambient temperature sensor.1 Please consult our interactive links below, to help determine which Hot Disk® instrument is best suited to your intended applications and needs.

Measurement Modules

Hot Disk® instruments can be tailored to specific testing needs not only by the selection of sensors, but also by the wide range of measurement modules available. These modules allow for the testing of samples of special geometries, thermal conductivity ranges and material types. The Isotropic Module is the standard module for measuring bulk samples, and is included in all instruments.2 The add-on modules in turn extend the capabilities of your instrument, for example to tackle anisotropic-, slab-, or thin film samples. Based on long client experience, Hot Disk conveniently offers its clients clustered configurations along with many instrument models, via grouping several modules of related interest together, or by providing for the full available range. In effect, this means Hot Disk customers have the option of ordering several add-on modules at a quantity discount. Please contact your local Hot Disk sales representative for available cluster options.

Sensors

We currently supply three different types of sensors to be used with our Hot Disk® instruments – configured in tandem with our range of Measurement Modules. All three sensor types make use of a TPS element – a patterned Nickel foil with electrically insulating cladding – that is used for simultaneous transient heating and precise temperature reading.

Our patented Hot Disk® sensor is our baseline sensor for measuring Thermal Conductivity and Thermal Diffusivity of isotropic samples. It is also used for testing 2D anisotropic samples, e.g. uniaxial crystals and layered composites with different properties in the in- and through-plane directions. Our patented Hot Strip® sensor is used as complement to our Hot Disk® sensor, primarily for testing 3D anisotropic samples, e.g. biaxial crystals and fiber composites with different properties along, across, and through the fiber orientation direction. Our Hot Cell® sensor is our newest type addition, developed in-house to measure the Specific Heat Capacity of materials or components (with focus on batteries) of arbitrary type, shape, and size.

Hot Disk® Sensors

Our patented Hot Disk® sensors are used for testing Thermal Conductivity and Thermal Diffusivity. They have a double spiral patterned Nickel foil, and come in three different claddings – Kapton, Teflon, and Mica. This encapsulation accommodates the Hot Disk sensor for a vast range of ambient temperatures, environments, atmospheres and surrounding media. The use of Nickel sensor spirals allows for very sensitive temperature readings, while the cladding provides electrical insulation, mechanical stability and durability.

Our sensors with Kapton insulation are designed to operate up to 300°C (or 400°C in oxygen-free environment), while our Mica-insulated ones function in the 300°C to 800°C range (or 1000°C in special cases). The Teflon-insulated sensors are in turn employed in acidic or corroding environments up to 250°C.

Hot Disk sensors come in radii ranging from 0.5 mm to 30 mm. Thus, small samples of high density as well as large porous samples of low density can be tackled with high accuracy. Our sensors are available either with or without cable appendages. Cables are offered in various claddings to suit the measurements in question: gray polymer for <50°C; red silicone for <180°C; or with white ceramic ring coils for demanding scenarios up to 1000°C. For cryogenic temperatures thin-diameter silicone-cladded cables are offered.

At temperatures above 500°C, our Mica-insulated sensors must be considered perishables, and are hence offered in bulk. Analogously, our Teflon-insulated sensors allow for measurements in corrosive environments/media, with lifespans correspondlingly limited. Finally, our Kapton-insulated sensors, handled with care and stored appropriately, typically offer years of reliable operation.

Our Kapton-insulated sensors are the most versatile in the Hot Disk® sensor portfolio, employed at temperatures from -253°C (20 K) to 400°C. They are mechanically highly flexible, and frequently attain a lifetime of several years when employed with care. The Kapton-insulated Hot Disk® sensors are available in seventeen models of different radii to date, catering to a wide range of sample sizes and topical applications.

Auxiliaries

To accommodate the testing needs of its clients, Hot Disk offers a spectrum of auxiliaries, either developed in-house or via trusted third parties. In this product category we offer solutions for temperature control via cryostats, bath circulators, convection-, muffle- and tubular furnaces. In addition, we arrange sensor switch units for scenarios where multiple-point and uninterrupted measurements are required from a single Hot Disk® instrument working with multiple Hot Disk®, Hot Strip®, or Hot Cell® sensors. We also offer a range of sample holders and sensor fixtures for all manner of sample geometries, types, and ambient temperatures. This as well as a wealth of practical items, such as sensor extension cables, PT100 ambient temperature sensors, and sample pressure control solutions. Hot Disk also offers a selection of verification samples, including ones of stainless steel, crystal quartz, and PMMA.

Temperature Control Units (TCUs)

We supply several third-party TCUs that together cover just about the complete sample temperature range of Hot Disk® instruments, which ranges from -253 °C (20 K) to 1000 °C. These TCUs have customized feedthrough for the dedicated Hot Disk® sensor cabling, and our accessories of Hot Disk® sensor interfaces and sample holders with inserts have been tailored to suit. They all have a temperature stability better than ±0.5°C, which is needed to perform measurements with high accuracy and precision using our instruments. The TCUs are automatically controlled via the Hot Disk® Desktop App to work in tandem with relevant Hot Disk® instruments.

It can, however, equally well be used for the testing of high viscosity liquids, pastes, gels, foams, and creams. For frozen samples, we recommend the use of our Kapton-insulated Hot Disk® sensor model 8563; this has a double-spiral diameter of 19.8 mm. For high-viscosity liquids, pastes, gels, foams, and creams, we advise Kapton-insulated or Teflon-insulated (for reactive samples) Hot Disk® sensors with somewhat smaller double-spiral diameters.

Hot Disk Sample Holder for Liquids
Sample Holder for Liquids
-60°C to 180°C

This sample holder is intended for testing liquids, including ones with very low viscosity (such as Toluene). Testing liquids is somewhat challenging, as the heating from the sensor can introduce natural convection in the relevant liquid, especially regarding low-viscosity liquids, which disturbs the measurement results. To minimize this disturbance the sample volume should be small, and hence the sensors will be of modest size. We therefore recommend the use of our Kapton-insulated Hot Disk® sensor models 5465 and 7577, having double-spiral diameters of 6.4 mm and 4.0 mm, respectively, for testing liquids. For reactive samples, our Teflon-insulated Hot Disk sensor models 5465 and 7577 (with some customization) can also be used.
