Product Overview
Based on ATST Electric’s core concept of “Precise Control, Safe and Reliable”, HM-2 Hour Meter is designed for recording the total operating time of electrical equipment. It accurately accumulates working hours when the device is powered, helping users monitor equipment usage and schedule maintenance effectively.
HM-2 is widely used in industrial and commercial systems where runtime tracking is essential for equipment management, maintenance planning and operational efficiency improvement. It provides a simple and reliable solution without complex programming or configuration.
With compact structure and standard panel/DIN mounting design, HM-2 can be easily integrated into control panels, distribution boards and equipment cabinets. It is suitable for long-term operation in harsh industrial environments.
