Scope of application:
Paper breakage tester is developed and produced according to the international general Mullen (Mullen) method. It is a special instrument for testing the breaking strength of various kinds of paper. Its performance parameters and technical indicators are in line with 1S02758 "Determination of paper breakage" and GB454 It is applicable to the testing of the breaking strength of all kinds of paper, and can also be used for the testing of the breaking strength of non-paper sheet materials such as silk and cotton.
Features:
1. High precision: high-precision pressure sensor is used, and the accuracy is controlled at <0.2%.
2. Superior technology: the instrument can measure the bursting strength value in the traditional sense, which is of great significance to the production and research departments.
3. Good airtightness and durability: the first-class copper oil cylinder and precise design and processing make the test system have good airtightness and durability, and the precision screw drive ensures that the instrument is durable.
4. Easy to use and operate: it can automatically complete the test, has the function of statistical processing of test data, and can be output by a micro-printer.
5. The test process is completed quickly and the result is accurate: high-precision pressure sensor, imported chip control.
6. Convenient for measurement and calibration: The calibration program is specially set inside the instrument, which is convenient for the measurement and calibration department (third party) to calibrate the instrument.
7. Diversity of unit selection: users can switch among units kpa, psi (Lbs/in^2), kgf/cm^2 according to needs.
