Description

automatic seed counter, seed counter, seed counters, vacuum seed counter , vacuum seed counters, LCD seed counter, lcd seed counters, auto seed counter, auto seed counters Product introduction Working theory: The seeds are arrayed and sent through electromagnetic vibrating box, then it drops into photoelectronic convertor and photoelectronic pulse is formed. Later it is sent into counting circuit and LED digit tube display the value. Pre-set please use disc switch. When the counting number reaches the pre-set value, the instrument will stop feeding and counting. Self-adjusted frequency is set for checking the accuracy of circuit and pre-setting.
