Klixon® Narrow Differential Control thermostat probes are designed to provide reliable, consistent performance over a long cycle life in the harshest environments. These probes provide accurately open and close with a narrow 2°F to 8°F differential, providing tight temperature control. Based on the M2 Series thermostat, these devices have outstanding vibration and shock resistance, with a temperature range from 0°F to 240°F.

These characteristics enable users to closely control the temperature in applications like aircraft environmental control systems or travelling wave tube (TWT) coolant systems.
