邯郸市自动化仪表厂和清华大学联合研制的型砂有效煤粉量测定仪用于测定型砂中有效煤粉含量和各种制造材料的发气性。应用单片微机处理,直接打印出有效煤粉含量和最大发气量数据属国内外首创,达到目前 Handan City, Automatic Instrument Factory and Tsinghua University, jointly developed a sand-type effective coal dust detector for the determination of the effective content of coal in the sand and a variety of manufacturing materials of the gas. Application of single-chip computer processing, direct print out the effective content of coal and the maximum amount of gas data is the first at home and abroad, up to now
