DPM 300Digital pocket microscope

The new DPM 300 digital microscope offers multiple magnification modes, up to 200x, making it suitable for most quality inspection work. The characteristic of a microscope is the use of an integrated LED lighting source, which can be turned on or off according to the application. DPM includes a high-resolution color camera that provides clear images. When capturing images, simply press the red button above the microscope. This microscope can be used in various applications, such as checking printing quality, paper structure, paint, textiles, plastics, etc. By using a special polarizing filter, DPM 300 is the right choice for dealing with high glare materials such as coatings, plastics, and metals.

Typical applications

Printing and Paper Industry
Point and Satellite Peaks
The "Dot" function measures the number of fixed points, average area size (mm2), and coverage area (%), as well as data corresponding to satellite peaks detected within a defined area.

line
The "Line" function automatically describes the characteristics of the leading and trailing edges of the line in terms of angle, blur, roughness, as well as line width (mm) and contrast according to the ISO 13660 specification.

outline
The "Shape" function automatically describes the area (mm2), width (mm), height (mm), and circumference (mm) of the target object within the defined area.

blank
If white or unprinted dots appear within the fully black area, a 'Void' can be detected. The blank must be within the range specified by the blank parameter. The DPM software can calculate the detected blanks within the selected area.

Spotted and granular
This feature describes how the full-color printing area can be uniformly displayed in front of the human eye. For "Graininess", high-frequency changes are described by small images (blocks) ranging from 0.042mm (0.0018mm2) to 1.02mm, while also being segmented into more small images (counts) by smaller blocks. Then, the variation between small images within a specific size grid is calculated according to the standard deviation (S.D.). After Zui, these small standard deviations are averaged into a single 'population' number.

Mottling "describes low-frequency patterns, where only a single 1.27mm grid is used to calculate deviation. According to the ISO 13660 standard, the minimum selected area should be 161mm2 (12.7mm x 12.7mm), and the DPM instrument must be installed on a bracket to obtain the patterns of 100 calculation blocks.

Paint and coating industry
Thickness of destructive coating
The V-shaped incision of the byko cut multi-purpose dry film inspection instrument can be easily saved as an image in mm as the unit of coating thickness. Measure and calculate the coating thickness based on the angle and width of the incision.

Coating Adhesion Test
Used to evaluate the adhesion of coatings. Save the image to the database of DPM software, observe the incision on the screen, and evaluate the edges, lines, shape, and defects of the grid image.

Brinell indentation
The Brinell indentation test is the most reliable testing method for evaluating the indentation resistance of plastic modified coatings. After testing, evaluate the length using the Distance Tool and convert the values using the Brinell indentation table.

Flexibility and elasticity
