Upcoming Training Sessions


We are pleased to announce that our longstanding on-site training has returned to its regular progression. A first session took place in November 2023 at the Hot Disk International Distributors’ Meeting in Munich, Germany, and a second will soon take place on April 17-18, 2024 here at our facilities in Gothenburg, Sweden. There are still available seats for this event. If you are interested, please don’t hesitate to reach out to us at info@hotdiskinstruments.com

We recommend that students (i.e. M.Sc. and Ph.D. candidates) successfully participating in one of our Training Sessions be awarded one (1) ECTS point.


At Hot Disk AB, we are proud of the quality and durability of our offered instruments and auxiliaries. As a standard feature and matter of course, we offer one year’s guarantee to all of our hardware components (standard-issue conditions and terms apply). This while our affiliated software is regularly updated free of charge; reflecting novel features, setup expansions and resolving of minor bugs. We also offer optional extensions of our instrument warranties, up to three calendar years. Please consult your local sales representative for relevant warranty quotes.


We offer our extant clients a range of instrument model upgrade options at favorable cost. This opportunity has been widely appreciated over the years. As laboratories grow and new applications ask for added performance and range, we are happy to accommodate our clients with suitable novel instrumentation. Configurations will be tailored precisely to your new circumstances and measurement wishes. Please contact your local Hot Disk representative regarding instrument upgrades.


As a result both of our successful upgrade program and the longevity of our instrumentation, we can to a limited extent offer new clients refurbished instruments at attractive prices.

Contract Testing

Contract testing is often offered by our Distributors and Business Partners for their local markets. Regarding more challenging applications, clients are invited to inquire via the Support Inquiries Form with the Hot Disk AB Head Office in Gothenburg, Sweden. Our Head Office has the full range of Hot Disk® instrumentation, temperature control accessories, and auxiliaries ready at hand. Our Application Specialist staff will consult contract testing clients carefully beforehand, and thereafter conduct the measurements according to agreed plan. Upon finishing the work, they will supply a comprehensive report, including sample description, relevant sensor model, instrument employed, accrued and tabulated measurement data, and finally an informed discussion of garnered results. Depending on the time constraints and volume in question, variations in the availability of contract testing may occur.

Customer-Collaborative Adaptations

Over the years, we have engaged in numerous projects with our clients, both within industry and academia. We have helped with the adaptation and integration of our testing equipment and capabilities in novel and complex application scenarios. Many of these applications have called for facilitating high-throughput QC testing for near-line or on-line production, involving simultaneous multiple-point QC testing and robotic QC testing. Successful applications have also been arranged for material research under harsh conditions and/or limited-space environments.

Hot Disk is always interested to explore such win-win collaborations. For Hot Disk they have frequently resulted in updated hardware, improved software, and new accessories, bringing benefits to all parties involved.


  • A QC-testing project called for the development of a customized fixture for the Hot Disk sensor, as well as for a thermally insulating background support. These, once fashioned to reliable standard, allowed for robust single-sided testing with a robotic arm.
  • Another QC-testing project prompted the development of a Hot Disk TPS 2500 S instrument with dual Hot Disk sensor ports. Once devised to exacting standard, these allowed for accurate, simultaneous dual-point testing.
  • A harsh-environment testing project involved the necessary modification of the regular Hot Disk sensor design. This, once achieved, allowed for related testing under extreme-pressure conditions inside a high-pressure tube.

If you need assistance or wish to consult with us in adapting or integrating our equipment to specific applications, please don’t hesitate to contact us! We naturally accept and encourage NDAs whenever wished for, while eager to align our instrumentation and TPS method to novel and topical applications.

Joint Research Projects

Hot Disk has long been involved in research projects with clients and partners, both within academia and industry, with topics ranging from advanced material research, novel product development, to new analytical practices. These projects concern both informal and formal collaborations, where several parties are at times involved. The projects in question are often co-funded by the partners, including Hot Disk, and frequently also by national or international funding agencies.


  • Within material research, an on-going collaboration between Chalmers University of Technology and Hot Disk toward the development of new synthesized thermoelectric materials, produced by Hot and Cold Pressure, Spark Plasma Sintering, and Crystal Growth technologies.
  • Regarding product development, an on-going European-Union-funded project titled “Hybrid and Organic Thermoelectric Systems” (https://cordis.europa.eu/project/id/955837 ), toward the development of organic-based thermoelectric materials and their implementation in devices. The relevant consortium consists of several academic and industrial partners, of which Hot Disk is one of the latter.
  • Concerning analytical technology development, a project involving the structural analysis and mapping of pathologies of equine hooves, with the University of Gothenburg. Farriers have traditionally been compelled to drill and gouge horse hooves to establish the extent of relevant damage. By contrast with the Hot Disk structural probe technique, the ambition is to develop a non-invasive, less debilitating and relatively inexpensive method of analysis.
  • If you believe Hot Disk can be a valuable partner in your research project, please don’t hesitate to reach out. We will be happy to jointly assess our potential role with you, on the assumption that our leading TPS method can be of assistance in your R&D efforts. Where you strive to fashion new products and services with our aid, Hot Disk conversely stands to gain new markets for its analytical acumen.
