8507型数字式金属热电势分选仪经过多年改进,于1987年6月10日在京通过部级鉴定。 该分选仪具有温差控制,因此对环境温度的变化不敏感,在0～40℃范围内对同一合金的测试结果基本相同,检测数据的稳定性和重现性亦较好。分选仪具有两级温差(55℃和85 After years of improvement, Model 8507 digital metal thermopower separator passed ministry-level appraisal in Beijing on June 10, 1987. The sorter has temperature difference control and is therefore insensitive to changes in ambient temperature. The test results for the same alloy are basically the same within the range of 0-40 ° C, and the stability and reproducibility of the test data are also good. Sorters have two temperature differences (55 ° C and 85 ° C)
