Information
Details
A compact and robust design for long term use and specially designed to fit the Seta-Shell 4 Ball Testers. Temperature control is achieved using an integral control thermocouple for external connection to a Seta Temperature Control System (19830-5). Hoses are connected via quick release valved connectors for convenient handling. A separate safety overtemperature thermocouple and controller is linked to the 4 Ball and will shut off the drive motor in the event of coolant flow failure. A knurled cap allows for easy hand tightening.
