LCD Hourmeter, EEPROM Memory, Epoxy Encapsulated
T44 Series
ENM’s series T44 Hour Meter features a 6-digit, 7 segment LCD
display. The accumulated hours are stored on powerless, non-
volatile data backup using CMOS EEPROM technology, where
small space and reliable instruments are required with memory
that does not rely on a battery. The unit is ideal for maintenance
applications. Hour meter displays hour glass and decimal point.
