The ENM Hour Meter/Counter T39FC49 is ideal for any application that requires recording both time measurement and event count for maintenance schedule. The two displays meter can operate independently or in parallel. This compact tamper-proof meter is protected from the environment to provide years of service. Accumulated time hours and counts are stored on powerless non-volatile data backup using CMOS EEPROM technology, where small space and reliable meter is required with memory that does not rely on battery.
