The Modutek C1115 MICROTEMP Process Controller Timer is a microprocessor-based instrument for precision timing and temperature regulation in industrial thermal bath applications. It delivers three-mode (P.I.D.) control of bath temperature, programmable countdown and count-through timer functions with pre-warn capability, and dual four-digit displays for simultaneous monitoring of process temperature and elapsed time. Safety is enforced through two independent thermocouple high-limit controls plus a dedicated thermal switch mounted on the quartz vessel; any safety threshold triggers automatic system shutdown. The unit interfaces via 10-key membrane keypad for parameter entry and displays operational status through eleven discrete LEDs.
