What Hot Disk Sensor Technology AB does
Hot Disk Sensor Technology AB (Hot Disk AB, doing business as Hot Disk Instruments) is a Swedish precision scientific instrument manufacturer headquartered in Gothenburg that designs and sells thermal conductivity meters, measurement modules, and sensors based on its proprietary Transient Plane Source (TPS) technique. Invented by co-founder Dr. Silas E. Gustafsson in 1989, the TPS method uses a thin metal-foil double-spiral sensor that functions simultaneously as a heating element and a resistance thermometer, enabling simultaneous measurement of thermal conductivity, thermal diffusivity, thermal effusivity, and specific heat capacity from a single transient heat pulse within seconds. The company's product platform comprises eight instrument models (ranging from the portable M1 educational unit to the flagship TPS 3500), more than ten measurement modules (including Isotropic, Anisotropic, Slab, Thin Film, Low-Density, Structural Probe, Single-Sided, Specific Heat Capacity, Automation, and Thermal Effusivity modules), and five sensor families (Kapton, Mica, Teflon, Hot Strip, and Hot Cell), supported by Hot Disk Desktop App software and a global network of distributors in more than 20 countries.
The company operates a B2B enterprise field-sales motion targeted at R&D laboratories, quality-control departments, and industrial manufacturers across battery, automotive, aerospace, polymer and composite, electronics/semiconductor, construction, and advanced-materials research end-markets, as well as academic institutions. Pricing is quotation-based with no public list prices, and revenue is generated through hardware sales of instruments, sensors, and accessories, recurring software updates, and professional services such as training, contract testing, and customer adaptations. The TPS method is codified as international standard ISO 22007-2 (2008) and ASTM E3088-25, and is referenced in over 6,000 peer-reviewed scientific papers, with more than 2,000 instruments installed worldwide since the company's founding in 1995.
