Proterm Handheld Tethered User Interface

The Proterm Handheld Tethered User Interface from Tinius Olsen is a familiar handheld controller that is tethered to the machine by an articulated arm. With its larger, tactile, sealed keypad, this controller is suitable for operators who use gloves to load and unload specimens and want a push button keypad. The controller can be used for standard operation of the tester and can start a test, but must be used together with Horizon software.

There are two tethered controller models: one designed for the operation with Tinius Olsen’s ST series testers, and one designed for operation with Tinius Olsen’s SL series testers.
