Introduction: PME-type grain counting instrument can count all kinds of main grain crops, such as rice, wheat, sorghum and corn grains automatically. In the agricultural college (agricultural college), seed system, grain department, Thousand grain weight is widely used. Technical Parameters: 1, counting varieties: PME type: (1) the size of the length × width less than 12 × 4 mm (small particles); (2) Size L × W <12 × 10 mm (Large particles) PME-1 type Size length × width less than 12 × 4 mm (small particles) 2, counting accuracy: ± 4/1000 with speed. (standard deviation) 3, counting speed: small particles greater than 1000/3 minutes; large particles 500/3 minutes 4, counting capacity: 1 ~ 9999 direct reading by the four LED digital tube. 5, self-school frequency: f = 1 ~ 2HZ f = 10 ~ 20HZ. 6, preset self-stop: 1 ~ 9999 any value, set 0000 does not count. 7, external power 220 ~ ± 20V ~ 50HZ power is less than 20 watts, good grounding. 8, instrument size: 304 × 234 × 180 mm. 9, the working environment: atmospheric pressure: 750 ± 30 mm Hg. Ambient temperature 0 ℃ ~ 40 ℃ Relative humidity: less than 80% at 20 ℃ Continuous use of time: more than four hours.
