Innovative thermal test systems with a range of -100 to 300°C for rapid, precise thermal cycling of electronics, chips and, IC's as well as semiconductors.    Low- and ultra-low temperature chambers and plates with a range of -185 to 500°C for rapid, precise thermal testing of components, sub-assemblies, and materials.
Low- and ultra-low temperature process chillers with a range of -100 to 300°C for continuous, reliable, process cooling in demanding applications.   ULT freezers, medical grade refrigerators, and biomedical cold storage products ranging from small and portable up to powerful, large-storage, -86ºC freezers to covering the entire range of cold chain storage.


Our broad portfolio and technologies allow us to deliver a temperature control system that matches your application. At inTEST Thermal Solutions, we don't force fit you into a singular product or technology. We leverage decades of experience and the industry's most comprehensive thermal toolkit to provide solutions that perfectly match your needs. It's what sets us apart.

Our thermal expertise expands across mechanical refrigeration, cryogenics, conduction, convection, liquid cooling and gas cooling — with temperature ranges from -185 to +500°C and anywhere in between.

inTEST Thermal Solutions is founded on a bedrock of engineering excellence. Our breadth of in-house capabilities allows us to be a single-partner-solution for thermal test and process cooling needs.

Our engineering expertise includes:

  • Controls Engineering
  • Electrical Engineering
  • Embedded Systems Engineering
  • Mechanical Engineering
  • Thermal Engineering
  • Software Engineering
Our four brands: Temptronic, Sigma Systems, Thermonics, and North Sciences combine for nearly 150 years of thermal system design and manufacturing. Today, we are at the leading edge of compressor-based refrigeration, cryogenics, conduction, convection, liquid cooling, gas cooling, resistive heating, thermoelectric technologies, and cold storage solutions. Proudly, we are one of the few companies in the world to achieve -100°C cooling without the use of cryogenics; but make no mistake, cryogenics are firmly within our competencies. Collectively, our portfolio of products offers an unmatched diversification of thermal test and process cooling solutions including:

  • Air Forcing Systems
  • Biomedical Cold Storage Solutions
  • Direct Contact Thermal Cyclers
  • Process Chillers
  • Thermal Chambers
  • Thermal Plates
  • Thermal Enclosures
With a broad range of products and engineering expertise at our fingertips, we regularly solve the most demanding thermal test and process cooling challenges including:

  • Exotic Heat Transfer Fluids
  • Extreme Temperature Ranges
  • Fluid Pressure and Flow Control
  • Frost Migration
  • High Ambient Operating Conditions
