Tinker & Rasors quartz Model QC controlled current interrupter allows synchronization of two or more interrupters at separate cathodic protection rectifier stations. The same accuracy can be expected as found in high quality quartz wrist watches. Simply select the time intervals, flip the switch, and the model QC will continuously cycle with precision.
Integrated circuitry assures long use under extreme field conditions. The instrument is housed in a rugged heavy duty aluminum case designed for easy battery access and with a protective cover for the panel controls.
