1、Reinforcement mechanical connection residual deformation tester consists of two high-precision variable-gauge extensometers with the same sensitivity, forming a double-sided extensometer, directly measuring the average deformation of both sides of the sample, and the measurement results are accurate; 2、Two extensometers can measure the gauge length, the range is 50-260mm, the range is 5mm or 10mm; 3、Real-time display of the true deformation of two extensometers, the value is stable and reliable; 4、The elastic connection between the double-sided extensometer and the steel bar is convenient, and the sample is convenient to clamp and has a long service life; 5、Measure the diameter of the steel bar (mm): φ5-φ40 6、Measurement resolution value (mm):0.001 7、Testing power Precision:grade 1
