3 Terms and definitions

The following terms and definitions as defined in GB/T 17446 apply to this document.

3.1 Automatic particle counter automaticparticlecounter; APC

An instrument capable of automatically counting and measuring the size of particles of a certain size range suspended in a liquid.

Note. The automatic particle counter is at least a particle sensor, a device that delivers a specific volume of liquid sample to the sensor according to the controllable flow, a signal processor, and a sensor

The size of the individual particles is converted into a composition of the particle size distribution analyzer and a device for outputting the particle size distribution results. Typical particle

The principle of dimensional measurement has the principle of scattering and shading.
