Geocorp: A Thermocouple Manufacturer

Since 1989, we have built a reputation of doing whatever is needed to take care of the customer.

Thermocouple manufacturing begins

In the first few years, we expanded rapidly and decided to start manufacturing thermocouples. This gave us more control of product availability, allowed instant purchase order acknowledgement, and provided the best material for the client's application.

Thermocouple wire braider purchased

In 1999, we placed an order for our first thermocouple wire braider. Now we have over 95 braiders that overbraid fiberglass, vitreous silica, and ceramic fiber insulations.
