Custom RTD Manufacturer in Los Angeles

AS9100D and ISO 9001:2015 custom Pt100 and Pt1000 RTD assemblies

Thermometrics manufactures custom RTD sensors, RTD probes, Pt100 assemblies, Pt1000 sensors, platinum resistance thermometers, and complete temperature sensor assemblies for industrial, aerospace, defense, process, sanitary, OEM, and machine protection applications.

Our Northridge, CA facility is in the City of Los Angeles, giving aerospace, defense, research, and industrial buyers local access to an AS9100D and ISO 9001:2015 certified temperature sensor manufacturer near El Segundo, Hawthorne, the South Bay aerospace corridor, and DCMA-driven supplier quality environments.

Custom RTD work usually starts when a catalog probe does not match the drawing, process connection, lead exit, temperature range, documentation package, or replacement fit.
