The Jumo EM-2 is a high-quality electromechanical thermostat designed for reliable temperature control and monitoring in a wide range of industrial and commercial applications. It operates on the proven liquid expansion principle, where a temperature change at the probe causes a volume change in the measuring system, which in turn actuates a snap-action microswitch. This robust design ensures high switching point accuracy and long-term stability. The EM-2 is suitable for use as a temperature controller (TR) or temperature monitor (TW), providing a dependable solution for thermal processes.
