SH series electric liquid crystal series digital counter, adopting 6-bit LCD driver liquid crystal showing, inner having the self-power (in lest lost power) The inner equipment sets manual zero reset (and plank zero reset), opt electronic isolating, having strong resistance to disturbance ability and adopting high-tech of slight-looser and slight-conductor, which can afford passive mechanic touch spot inputting specification according to clients requirement. When tested dynamic equipment rotated one time, the lasting time is just as the opening switch signal time of this equipment, through accumulated unit and frequency unit selectively accumulated as run time (hour), run frequency (single gauge, single accumulated, accumulated time and numbers, no-power input, voltage power) which can order according to customer requirement.
