laboratory automatic seed counter

automatic seed counter   Concise intorudtion:   Automatic seed counter for the determination of the weight per thousand kernels of seeds and for the preparation of samples for germination and cultivation tests. It fits for seeds size from the smallest to biggest sample. From onion seeds to soybean, corn seeds.
Features:    1 Count Range: Small and middle sample: 0.7~4 mm×0.7~12mm   Big sample: 3~10mm×3~12 mm  2 Count Accuracy: Big and middle sample: 2/1000 small sample: 4/1000                      3 Count Speed: ≥1000 /3min (it's based on level 2, if you want fast you can turn to level 3-7)  4 Count Capacity: 1~99999    Working principle:   The feed container is held in place by an electromagnet and vibration induced during counting. The material to be counted reaches the outlet and falls into the receptacle through a photoelectronic counter.    Operation tip:   The Counter selects its counting speed automatically dependent on the size of the material to be counted. This guarantees optimum use of the counting capacity and reduces counting time to a minimum whilst maintaining count accuracy. Shortly before counting is completed the counter reduces its counting speed so that no more seeds are counted than have been preset. Counting speed may also be manually adjusted. The instrument can recognize when the receptacle or the feed container is absent, stops counting and reports the fact on the display so that no operating faults occur. Particles which are significantly smaller in size are not counted. Thus, for example, rape seeds in a sample of peas drop into the receptacle without being counted. By manually adjusting the seed size it is possible to control the counting of particles. 
    The display shows in automatic mode the preset quantity and the count so far. In manual mode it also shows the counting speed selected and the seed size. The keyboard is used to select various modes of operation, such as summation counting and differential counting.   Photo reference:
