Abstract: In order to calibrate the performance of model 3936 scan mo bility paticle sizer, the testing principles of this instrument were present ed and out the factors influenced on its performance were pointed out. Then, the flow rates and the accuracy of particle size measurement was studied through experiment methods. The study indicated that using stan dard particles to calibrate the accuracy of particle size measurement was a good method to evaluate the performance of this instrument, the calibra tion results satisfied the measurement demands. Some useful informations for the evaluation and calibration of thistype instrument were provided.
