Elongation tensile tester

Performance Characteristics of Product ◆Executive standard: GB/T4074.3-2008/IEC60851-3; Inspection standard: JB/T4279.3-2008 ◆Used to test elongation (ductility) of copper wires covered with φ0.100-φ3.000mm enamel, silk or other insulation materials and other metal wires with tensile strength ≤2000N; ◆Application of SCM control allows for fast operation and strong anti-interference capacity; ◆Preset elongation of samples with two-digit toggle switch and, when the preset value is reached during test, motor and counter would automatically stop action and display results; ◆The instrument is capable of measuring elongation while also the tensile force and holding the maximum tensile force value during stretching; ◆Clamps are designed according to characteristics of various wires to prevent samples from breaking at clamp jaws, easy to load samples and, after samples are compressed, enamel can be automatically broken; ◆While sample is broken, movable clamp would automatically stop moving, with error between displayed and actual elongation value less than 1%; ●Optional Model: ◆SC-5C elongation and tension tester (copper-clad aluminum conductor) ◆SL-A elongation and tension tester (microwire, maximum load 5kg) Major Technical Parameters Start distance between two clamps (200mm or 250mm) ±0.5mm two modes adjustable Stretching speed of sample 300±60mm/min Maximum elongation testing range ( displacement distance of movable clamp) ≥80﹪(≥160mm) Display of elongation Three-digit LED automatically displays test results with accuracy of 0.1% Display of tension value Four-digit LED automatically displays test results with accuracy of 0.2% Input power AC220V±10%  50Hz Consumed power ≤200W Overall dimensions L×W×H  640×400×420mm Weight 45kg   ●Optional range of sensor: ◆Microwire:  20N, 50N, 100N, 200N and 500N ◆Medium and large wires: 1000N, 2000N, 3500N and 5000N
