The invention relates to the technical field of sample concentration measurement, in particular to a measurement method combining a scattering turbidimetry and a transmission turbidimetry. The randomerror epsilon and the offset f of each turbidimetry are combined, the total error TE of the two turbidimetry is obtained respectively, then the two total errors are compared, if the two total errors are different, the measurement method with the small total error is selected as a quasi value, and if the two total errors are the same, the mean value of the measurement values of the scattering turbidimetry and the scattering turbidimetry is taken as the quasi value. The measurement method is high in measurement accuracy. 本发明涉及样本浓度测量技术领域，尤其涉及一种联合散射比浊法和透射比浊法的测量方法。它结合每个比浊法的随机误差ε和偏移f，分别得到两个比浊法的总误差TE，然后将两个总误差相比，若两个总误差不相同，则选择总误差小的测量方法作为准值，若两个总误差相同，则取散射比浊法与散射比浊法两者测量值的均值作为准值。这种测量方法测量准确性较高。
