ESN Type 8434-RKS Electronic Thermostat

In view of the option to specify the trigger value and the reset value in steps of 1°C within a wide measuring range (this must be specified explicitly when ordering), these thermostats (temperature sensors) or the 8434 series are especially suitable for applications that place high requirements
concerning switching accuracy and reproducibility.
