Hot Disk M1
Heat conductivity measurement for the slim budget

The Hot Disk M1 is a basic Thermal Conductivity Meter which nevertheless offers high accuracy and measurement repeatability. With the M1, solids, powders and pastes in the thermal conductivity range of 0.03 to 40 W/m/K are readily tested.
Hot Disk TPS 500
The ideal system for the small-scale lab

The Hot Disk TPS 500 Thermal Constants Analyser rapidly and accurately measures the thermal conductivity, thermal diffusivity and specific heat capacity of a wide range of materials and is therefore an excellent step-in Thermal Conductivity Meter.
Hot Disk TPS 500 S
Flexible system with excellent price performance ratio

The TPS 500 S measures the thermal transport properties of solids, pastes, gels and powders and encompasses similar accuracy and sample size flexibility as the benchmark TPS 2500 S or workhorse TPS 1500 (the latter two instruments are designed according to ISO 22007-2).
Hot Disk TPS 1000
Hot Disk TPS 1000 – the most flexible, adaptable thermal conductivity instrument on the market – attractive price and compatible with ISO 22007-2

The TPS 1000 is aimed at users who process recurring questions in a defined area of application, as is the case in quality assurance, for example. It combines top performance with an affordable price and complies with the ISO 22007-2 standard.
Hot Disk TPS 1500
System for bulk samples with several options and upgrade possibilities – meets ISO 22007-2.

The precise and robust Hot Disk TPS 1500 is ideal for characterizing and testing building materials, insulation materials or any other type of large bulk samples. The TPS 1500 meets ISO Standard 22007-2.
Hot Disk TPS 2200
Universal Tool for R&D and QC for a broad range of different materials– meets ISO Standard 22007-2

This general-purpose R&D instrument is designed for precision analysis of thermal transport properties. The TPS 2200 covers a significant span of materials of various geometries and dimensions, including solids, pastes and liquids. I can run all optional measurment modules and meets ISO Standard 22007-2.
Hot Disk TPS 2500S
The Hot Disk TPS 2500 S is the flagship instrument in the system portfolio of Hot Disk AB and covers an extensive range of materials of various geometries and dimensions - meets ISO Standard 22007-2.

This general-purpose R&D instrument is designed for precision analysis of thermal transport properties – including thermal conductivity, thermal diffusivity and specific heat capacity. The TPS 2500S covers the range from 5 mW/mK to 1800 W/mK and with the possibility of very short measurement times you can run also very small bulk samples, thin films or coatings.
Hot Disk TPS 3500
Testing the extreme – when you have very small and very high conductive samples this is the ideal instrument for testing heat conductivity, thermal diffusivity and specific heat.

The capabilities of TPS 3500 go well beyond that of any other Hot Disk instrument to date, while retaining the documented precision of all TPS thermal conductivity meters. Short measurement times down to 0,1 second and high end electronics enables measurements on extrem good heat conducting as well as small samples - it meets ISO 22007-2.

HOT DISK - ISO 22007-2
The standard DIN EN ISO 22007-2
The hot disk measurement technique is described in detail in this ISO standard - you can find out what is important here

The official title of this standard is „Plastics - Determination of thermal conductivity and thermal diffusivity - Part 2: Transient plane heat source (hot disc) method (ISO 22007-2:2015); German version EN ISO 22007-2:2015“ - it can be purchased from the Beuth Verlag at the following link

Hot Disk Software
Easy to handle software package for experiment design and calculating the results

The Isotropic Standard Module is the core, featured in all configurations. The user defines here all parameters and the module is running the experiment. The standard module allows the Hot Disk user to measure the thermal conductivity, thermal diffusivity and specific heat capacity of any isotropic bulk sample, whether a solid, liquid, powder, paste or foam.
Hot Disk – Optional Measurement Modules
Optional Modules add new capabilities to your Hot Disk configuration

Hot Disk devices can be tailored to your testing needs also by the range of measurement modules available. These modules allow testing of samples of different geometries, thermal conductivity ranges and material types. The Isotropic Standard Module is the core, featured in all configurations, whereas the optional modules will add new capabilities to your Hot Disk configuration.
