According to the company, Camsizer 3D can carry out a 3D measurement of a sample using a ‘particle tracking’ function. This requires two cameras to capture several individual images of different orientations of the same particle as it moves through the measurement zone.
Microtrac says that this technology ensures that the true size and shape values are recorded – especially the length measurement of stretched particles such as extrudates. “This is a decisive advantage compared to conventional 2D particle analysis, where the particles are captured in arbitrary orientation and do not show their ‘true’ length,” a press release said. The 3D method also reportedly offers better accuracy for detecting defective or broken particles.
The dual camera system has a measuring range from 20 µm to 30 mm.
