ENM’s Series T39 LCD, 6-digit hour meter and up or down counter is ideal for any application that requires recording both time measurement and event counting in scheduled maintenance applications. Performing regular, scheduled maintenance extends the life of your equipment and reduces costly down time. The two displays can operate independently or in parallel. This compact, tamper-proof meter is epoxy encapsulated to IP67 and protected from the environment to provide years of uninterrupted service. Accumulated time hours and counts are stored on powerless, nonvolatile data backup using CMOS EEPROM technology, where small space and reliable meter is required with memory that does not a battery. Now available in AC voltage.
