Introduction: The model EA108 adopts the up-to-date electronic counter cover and 8-bit LCD display with zero hiding for digits above units, and features strong anti-interference and convenient application. It is driven by voltage pulse, a proximity switch, a shaft encoder or a mechanical contact switch. If the power supply is interrupted, the data will be stored in EEPROM (storage) which can keep the data for at least ten years without power. When the power supply restores, it continues counting.
