Product description:

Product Name: Electronic Accumulating Counter 711A
Working principle & Introduction: The model 710A is newly developed to meet the needs of Chinese market on the base of Germany Hengstler product. It adopts highly-integrated chip components with small space usage and strong counting ability and conducts high-frequency counting under the drive of voltage pulse, a proximity switch, a photoelectrical switch, a shaft encoder or a mechanical contact switch. This counter can be reset both by the front panel and by the external electrical signal, simple for use. Its unique internal memorizer can keep the data for ten years without batteries during power failure or power off. The 6-bit red nixie tube (LED) display is high in definition, easy to be identified and hard to be impacted by temperature and light, and applicable to interrupted zero restoration counting, such as statistics counting, mechanical revolution, currency counting, flow counting, and group counting in packaging, textile, mechanical and dying industries.
