Yunda YD-TQD-A Paper Air Permeance Tester 0~2500mL/min

YD-TQD-A

Paper permeability Tester (7 inch screen)

Touch screen display in Chinese and English, using chips imported from the United States, commonly used in Encasement paper and cultural paper testing, with a test area of 10cm ² and a linear error of less than or equal to 1%.

Introduction

The computerized porosity Tester uses new technology and common testing methods to test the air permeability of paper, cardboard or other sheet objects. This instrument is a fully automatic instrument controlled by a single-chip microcomputer, which can meet the requirements of various test methods such as Schober, Bendtsen and Gurley. It is widely used in domestic (CN) papermaking, packaging and cigarette industries.

Standards

GB/T458, ISO5636/2, QB/T1667, GB/T22819, GB/T23227, ISO2965, YC/T172, GB/T12655.

Principle

Using the principle design of the pressure difference method, the pre-treated sample is placed between the upper and lower measurement surfaces to form a constant pressure difference on both sides of the sample. Under the action of the pressure difference, the gas passes through the sample from the high pressure side to the For low-pressure side flow, the air permeability of the sample is calculated according to the area, pressure difference and flow rate flowing through the sample.

Features

① Imported chips: The chips and sensors of the instrument are imported from the United States, with accurate test results, good repeatability and high precision.

② Exquisite design: The instrument adopts microcomputer technology, and the testing process is fully automated, fast and accurate. The touch screen LCD displays the results, and has data recording and processing functions, with printout.

③ Superior performance: Compared with the traditional air permeability meter, this instrument has a high advantage. For paper with low air permeability, a higher pressure difference can be set, while for paper with higher air permeability, it can be set Set a lower differential pressure for easy and accurate measurement results.

④ Easy to use and high automation: The traditional air permeability Tester is not only slow and laborious, but the test of the air permeability Tester is automatic and fast, and the accuracy of the test results is also guaranteed. Misoperation or low reproducibility of test results, which are caused by poor instrument design and manufacturing techniques, are effectively avoided in this instrument.

⑤ Wide range of application: The instrument has three models (Type A, Type B, and Type C), and its range covers all paper air permeability tests. Among them, type A is often used for wrapping paper and cultural paper (such as paper bag paper, filter paper, thermal paper, etc.), type B is often used for paper in the tobacco industry (such as cigarette paper, tipping paper, striped paper, etc.), and type C is often used for Perforated paper (eg, molded paper, tea filter paper).
