DigiTrace was initially launched in 1985 to offer a much-needed control and monitoring system for the heat tracing industry. The norm at the time was to use bulb and capillary thermostats to provide crude on/off setpoint control. The DigiTrace 720 was developed to deliver industrial users a solid-state controller with state of the art monitoring, excellent reliability, lower energy and maintenance costs, and a tighter window of control for their electric heat tracing applications.
