INTRODUCTION: This series of seed counters can count grain products, such as paddy, wheat, sorghum, maize and so on granules automatically. They're widely used in Academy of Agricultural Sciences, agricultural colleges, seed systems, food sector indicators such as seed inspection and measurement thousand seed weight.
Model BLH-6200B is suitable for small granues only like wheat; While BLH-6200A is suitable for both small granues like wheat and large granues like maize(corn).

TECHNICAL PARAMETERS:
1, Counting accuracy: Plus or minus 4 / 1000 in order to set the speed (standard deviation)
2, Counting speed: Small particles is greater than 1000 / 3min, large particles 500 / 3min
3, Counting capacity: 1-9999 by four LED digital tube direct reading
4, Self-calibration frequency: F = 1-2Hz f = 10-20Hz
5, Preplaced automatic stop: 1-9999 were arbitrary value, set 0000 does not count
6, External power supply: 220 plus or minus 20V, 50Hz
7, Power: <20W, a good grounding
8, Working environment:
8.1 Atmospheric pressure: 750 plus or minus 30 mmHg
8.2 Ambient temperature: 0-40 centigrades
8.3 Relative Humidity: 20 centigrades, <80%
8.4 Continuous using time: > 4h
