PDT-01 Paper Dirt Tester

PDT-01 Paper Dirt Tester is made according to GB/T 1541“Paper and board-Determination of dirt”. The degree of dirt is the amount of dirt with a certain area per square meter of paper and cardboard, or the equivalent area (mm2) of dust on paper and cardboard per square meter.

Significance

Dust is a type of defect of paper appearance, which can be inspected by eye, hand, and nose. It is impurities such as black, yellow, dark yellow, yellow brown, or brown dots that are significantly different from the color of the paper.

A high degree of dirt will reduce the printing quality. In the printing of coated paper, cardboard, and white cardboard, especially in color printing, the effect of the degree of dust is particularly obvious, affecting the printing quality.

The PDT-01 Paper Dirt Tester Application

The PDT-01 Paper Dirt Tester is a soil pH test kit that comes with 100 test strips with a range of 3.5–9. The strips should be used within 90 days of opening and have a shelf life of two years.

Touch the litmus paper to the soil-water solution
Match the color of the litmus paper to a pH chart
If the soil fizzes when vinegar is added, it might be acidic
If the soil doesn’t fizz when baking soda is added, it might be more alkaline
