DJ-CA100 Cleanliness Analysis System
High-performance Technical Cleanliness Inspection System
Applications
DJ-CA100 Cleanliness Analysis System full compliance with the requirements of VDA 19.1-2015, ISO 16232, ISO4406 and ISO 4407, QV11111 and customer-defined standards. Adopted optical polarization technology, manually rotate the polarization device, the metallic luster reflection properties of all pollutants on the entire filter can be determined by two scans. At the same time, according to the morphological definition of fiber in VDA19.1 (stretch length/maximum inscribed circle diameter>20, maximum inscribed circle diameter≦50 microns), the classification and classification of the following four types of particles can be quickly and automatically completed within a few minutes. Size measurement: reflective particles, reflective fibers, non-reflective particles, non-reflective fibers.

standards can be entered for automatic Testing of cleanliness and particle size; fiber statistics can be performed; The system regularly updates the latest standards.
Scanning sample and settings diversified
Supports scanning areas of various shapes: rectangular area, circular area, etc., supports multiple scanning paths to meet the needs of various applications;
Auto-capture, positioning, and retrospective remake
Auto-capture in the scanning process, auto-save, progress is visible in real time; photo information save to the database and simply to inquire;
And the information and pictures of the sample can be encrypted to prevent unauthorized viewing and modification. Provides the viewing and checking function of the field of view pictures, which can realize the functions of Positioning backtrack, fixed-point view or re-photograph of each field of view.
Innovative automatic polarized light technology, scanning the filter once, realize the identification of metallic and non-metallic reflective particles
The cleanliness testing system adopts innovative automatic polarized light technology. It only needs to scan the filter film once to appraisal the metallic and non-metallic reflections of the particles on the filter film. Compared with the traditional polarized light technology, the filter film needs to be scanned twice (1 time under orthogonal polarized light and 1 time under parallel polarized light), the scanning Testing time is doubled.
The system can auto-set the prescribed exposure time and threshold in compliance with VDA19.1-2015
It can auto-set the prescribed exposure time and threshold, perform sample testing to meet the requirements of the above-mentioned standards. At the same time, the functions of manual exposure and manual threshold are still retained, and users can freely choose according to their needs.
In order to make the analysis results comparable,VDA19.1-2015 has clearly stipulated the threshold parameter of the image gray scale of the optical microscope that uses the polarization to distinguish between particles and the background of the filter film.: the maximum gray value of the filter film background must be set At 55%±5% of the entire gray value (by adjusting the light source brightness and camera exposure time), the binary threshold is set at 70% of the maximum gray value, and the part on the left side of the gray threshold is recognized as particles.
Supports super-large particles across the field of view and auto-calibration the offset, so that pictures can be seamlessly stitched.
The system auto-recognizes particles, auto-analyzes particle types, auto-counts particle parameters, and supports modification of particles; provides multiple statistical analysis tools: particle list, statistical results, etc.;
Measurement statistics and analysis
The system auto-recognizes particles, auto-analysis particle types, and auto-counts particle parameters. multiple statistical analysis tools can be provided: particle list, statistical results, etc.;
Cleanliness Testing Report (VDA19)
Support template report generation mode, including statistical data, rating, filter picture, maximum particle photo and other information; Multiple report modes are available.
