Tensile Tester

The LB-KZY series computer tensile strength tester is used to measure the tensile strength of paper and paperboard:Tensile strength, tensile strength, elongation, breaking length, tensile energy absorption, tensile index and tensile energy absorption index.

The instrument can automatically calculate the above test results, and through the printer to directly print the test results data, test sensitivity, high precision, accurate and reliable, use the vertical tensile measurement method, ergonomic design, intuitive user interface.

Product features

Using high precision force sensor, the factory accuracy control in <0.5%, better than the standard ISO + 1%, using stepper motor, precision ball screw drive, in addition the reasonable design, precision machining, to ensure that the instrument of high repeatability, durable, the company specializes in the design of programming can be used later to upgrade equipment, to ensure the leading level of the instrument.

LCD Chinese display, friendly man-machine interface operation, fully automatic test, with test data processing function, micro printer output.

The preset clip distance and test speed make the test faster and more efficient.

The force sensor is connected with the upper collet at the upper part, and the user or the measuring and calibrating Department (third party) hangs the standard weight on the upper collet, so that the instrument can be calibrated easily.

Test description

Sample with uniform sampling equipment from the sample cut from the prescribed standards such as toilet paper for the longitudinal and transverse width of each 10, (15 + 0.1) mm, the test length is 50mm, set the initial speed to 5mm/min + 1.25 mm/min to make a prediction test selection can make the fracture time of not less than 5 seconds and not more than 30 seconds to test speed, determination of the longitudinal and transverse 10 valid data (data invalid fracture distance within 10mm clip, and report the results from) three significant digits.

Note: different papers are carried out according to the test requirements specified by the relevant standards.
