The panel mounted Digital Temperature Monitors (DigiTemp 2310N) are designed to interface with any specified RTD or T/C sensor. In addition to temperature indication in °C, they incorporate provisions for alarm outputs which can be tailored by the user, at site, to suit HI/LO and Fail-safe/Nonfail-safe alarm requirements.
