Marlin Thermocouple Wire manufactures thermocouple wire and cable for power generating plants and utilities from our Westlake, OH facility.
Power engineering and generating plants use Marlin thermocouple and extension wire for turbine, boiler, and balance-of-plant temperature circuits, with connectors and jack panels for control rooms.
Industry buyers need constructions, documentation, and connectors that match process duty—not generic commodity wire.
We manufacture specialty thermocouple products, run a NIST-traceable lab, and sell to both end users and distributors across the United States.
