Electromechanical counters record the number of pulses received through an input, displaying the count with rotating numerical digits. These counters total the number of times a process runs and the time the process takes to run. They hold their count in the event of a power failure, are less affected by electromagnetic interference and are more durable than digital counters. Applications include manufacturing and automation, as well as office and medical equipment.

Digital counters record the number of pulses received through an input and display it on a screen. They total the number of times a process runs and the time the process takes to run. These counter timers are used in manufacturing and automation applications and office and medical equipment.
