The Model 378 is a high performance industrial grade digital indicating single set point PROPORTIONAL /ON-OFF controller for use with type K, J, thermocouple. Thermocouple gain and cold junction are automatically compensated by internal electrode circuits. An accurate 1 mV per display count analog is provided to interface the instrument with a recorder,printer and so on.
