The horizontal photovoltaic welding tape peeling force tester uses a PC and an interface board to collect, save, process and print test results. It can calculate: maximum force, tensile strength, elongation at break, maximum peel force, minimum peel force, average peel force, maximum peel strength, minimum peel strength, average peel strength, range, ring initial adhesion, unwinding force, puncture force, puncture strength, bag sealing force, adhesive strength and other parameters; it can perform multi-curve processing, multi-sensor support, graphic interface, flexible data processing, MS-ACCESS 2003 database support, making the system more powerful. Supports multiple languages to switch at will. The database field display name of the test data is automatically translated with the selected text, making the data easy to browse in the local text, meeting the use of the test machine all over the world; supports 3 types: SI international standard unit, kg-cm unit, Lb-Inch imperial unit, 6 common units: N-mm-MPa, kN-mm-MPa, gf-cm-kgf/cm, kgf-cm-kgf/cm2, Lb-Inch-kpsi, kP-Inch-kpsi, easy to switch units. Meet the use of standards in different regions.
