Isotech North America is a small, Colchester, Vermont-based specialist in temperature metrology, focused on designing, manufacturing, and applying precision calibration standards. With more than 30 years of experience, the company supplies both metrology laboratory equipment and industrial calibration tools used in the field. Its offerings include devices such as thermometry bridges, standard platinum resistance thermometers, and fixed-point cells, along with portable dry-block calibrators, liquid baths, furnaces, infrared calibrators, and thermocouple referencing systems. The operation includes an ISO/IEC 17025 accredited laboratory, delivering measurement uncertainties that are smaller than many national measurement institutes, and it provides NIST-traceable calibrations from its U.S. facility serving the Americas.

Customers include primary laboratories such as NIST and NRC, accredited laboratories, defense organizations, pharmaceuticals, and oil and gas companies, reflecting a broad, regulated-market focus. In 2021, Isotech North America signed a contract with the U.S. Navy to design and develop approximately 700 next-generation dry-block temperature calibrators, illustrating expansion of its calibration capabilities for large-scale applications.
