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.
Product features:
1, high precision: the use of high precision pressure sensor, accuracy control in < 0.2%.
2, superior technology: the instrument can measure the traditional sense of rupture value, which is of great significance to the production and research departments.
3, good sealing, durable: first-class copper cylinder and precision design and processing make the test system has good sealing and durability, precision screw drive, ensure the durability of the instrument.
4, easy to use, easy to operate: can automatically complete the test, with the test data statistical processing function, micro printer output.
5, the test process is quickly completed, the result is accurate: high precision pressure sensor, imported chip control.
6. Easy to measure and calibrate: the calibration procedure is specially set inside the instrument, which is convenient for the measurement and calibration department (the third party) to calibrate the instrument.
7. Variety of unit selection: Users can switch between kpa, psi (Lbs/in^2) and kgf/cm^2 according to their needs.
