Zero Span Tensile Tester is used to test the zero tensile strength of laboratory paper sheets. Dry or wet laboratory sheets are made from the slurry, and the measurements can be made wet (undried), dry (humidified), or remoistened. The specimen is clamped on the tensile strength tester with zero clamping distance, and the specimen is stretched until it breaks. Determine the maximum value when the sample breaks, and calculate the zero-span tensile strength and tensile index.

● The instrument adopts high-precision load cell, ball screw and three guide shafts, and the transmission is stable and accurate.
● Adopt closed-loop stepping motor, low noise and precise control
● Cotex-M4 ARM processor, 24-bit imported analog-to-digital converter, improve the response speed and test accuracy of the instrument.
● Sudden power failure data storage function, the data before the power failure can be retained after power on and the test can be continued.
● Real-time display of the tension-displacement curve during the test.
● Test data can be exported to USB flash drive.
● The system and screen software can be upgraded through the network or USB flash drive.
● Supports a variety of communication methods, online software (purchased separately) can be WIFI or USB communication.
● Test data can be uploaded to cloud server, and paper test data can be monitored in real time with QMS paper quality management system (purchased separately).
