LinkPhysics (Shanghai Keshun Technology) does not present itself primarily as a SaaS or enterprise software provider. Instead, its main business is the manufacture of scientific research instruments and solutions focused on low temperatures, magnetic fields, and probe stations. Founded in 2008, the company shifted toward independent R&D and production after 2018, providing semiconductor test systems and low-temperature research equipment for universities, research institutes, and high-end manufacturing R&D centers.
Its product line is fairly broad, covering liquid-nitrogen high/low-temperature probe stations, 4K closed-cycle cryogenic probe stations, low-temperature high-magnetic-field probe stations, superconducting magnet systems, liquid-helium/liquid-nitrogen cryostats, Hall effect measurement systems, 3D magnetic field test platforms, low-temperature temperature controllers, sensors, cables, and cryogenic accessories. Some models disclose fairly detailed specifications. For example, the PSM-LN2 series provides an 80K–800K high/low-temperature vacuum testing environment and supports external electrical measurement instruments for testing voltage, current, resistance, IV curves, and more. The 4K closed-cycle probe station emphasizes low vibration, no liquid helium consumption, and wide-temperature-range testing.
The website does not provide standard packages, subscription pricing, or online purchase configurations. Overall, it appears more like project-based equipment procurement. Its service center highlights non-standard customization, solution confirmation, production acceptance, on-site installation and commissioning, operation training, and after-sales maintenance based on customer needs. This model is reasonable for scientific instrument procurement, but budget evaluators will still need to contact sales for quotations, lead times, warranty terms, and optional accessory lists.
The advantages are a comprehensive product matrix covering low temperatures, magnetic fields, probe stations, Hall testing, and an accessory ecosystem. The company also discloses certifications such as ISO9001 and has service touchpoints in Shanghai, Beijing, Hefei, Shenzhen, and Sichuan, making it suitable for domestic research customers in China. The drawbacks are that this is not a SaaS product and lacks key enterprise software information such as team collaboration, permissions, cloud deployment, data security, and API platforms. Some content involves represented brands and general instrument Q&A, so the boundary between self-developed and distributed products should be confirmed before procurement.
It is suitable for laboratories in semiconductors, quantum devices, condensed matter physics, magnetism, superconducting materials, and related fields, for electrical, optical, Hall, and magnetotransport testing under low-temperature vacuum and magnetic-field environments. The website has an ICP filing and domestic contact information, so access from China appears to be directly available.
