<p>To facilitate evaluation of a measurement condition in order to set an optimum measurement condition for each sample. A particle size distribution measuring device is provided with: a device main body 2 that measures a particle size distribution of a sample; and an interface device 3 that receives an input from an operator to perform drive control of the device main body, and receives a measurement result from the device main body to display the measurement result. The interface device 3 displays, in a graph, a relationship between values of operational parameters, which are to be set to treasure the particle size distribution, and values of evaluation parameters obtained by using the measurement result from the device main body, which correspond to each of the values of the operational parameters. The operational parameters may include for example sample circulation rate, intensity of an ultrasonic wave or refractive index of the sample. The evaluation parameters may include for example mean, median or mode particle diameter. The device main body 2 may be of a diffraction or scattering type (Fig. 2).</p> |
