Design efforts began on a line of monitoring devices for sensing the condition of three-phase power lines. Time Mark product lines have expanded greatly, as customers needs increased and requests were met. Time Mark Corporation products are distributed throughout the United States and exported to an expanding international customer base. Standard catalog products are marketed through a combination of local distributors, Time Mark representatives, and direct sales personnel. Time Mark products are marketed under two trade names: "Time Mark", which includes the basic lines of industrial controls, and "Signaline", which is a recognized brand name for all of our timing devices.
