Mechanical Hour Run Meters are robust, electromechanical instruments used to record the total operating time of machines, motors, and equipment. Using a precision synchronous motor or electromagnetic counter mechanism, these meters provide permanent, tamper-proof tracking of run hours — ideal for maintenance scheduling, warranty monitoring, and performance analysis. Charter Controls supplies a complete range of mechanical hour counters designed for long-term accuracy and dependability in industrial and commercial control systems.
