BT-1600 Image Particle Size Analyzer

 

BT-1600 image particle analysis system is multi-functional including image distribution test and particle shape analysis. The integration of the traditional microscopy and advanced image processing technology, it consists of optical microscope, CCD camera, image acquisition system, computer, printer, etc. The basic operation is performed by firstly taking the picture of the image in microscope by a special camera, secondly transmit the image obtained to the computer by image acquisition system, thirdly process and analyze the image in special particle size analysis software, finally output the result through monitor and printer. It is characterized by direct-image, direct-view, accuracy, broader range, automatic recognition, statistics and quantification. In addition to examining the shape of the particle, it gives particle size distribution and the ratio of length to diameter (L/D), etc. therefore it becomes a new method for particle size test in scientific research and production field.

Principle

Calibration Method: Calibrate the size of each pixel by standard special graduated scale of the microscope, after that measure the size of the image by calculating the number of pixels. The unit is um. Test principle: Through the statistics of the number of the particle and the number of the pixels occupied by each particle, the area of equivalent circle and the volume of equivalent sphere are obtained, therefore diameter of equivalent circle area, diameter of equivalent sphere volume and L/D, etc. are obtained. How does BT-1600 measure size of particles: It uses 100 pixels as one unit for convenient calculation. Table 1 shows particle diameter of 100 pixels under different objective amplification
