HDL series digital universal tensile testing machine

HDL seriesDigital universal tensile testing machine

1、 Main purpose:

HDL seriesDigital universal tensile testing machineSuitable for tensile testing of materials such as rubber, plastic, textiles, waterproof materials, wires and cables, mesh ropes, metal wires, metal rods, metal plates, etc., with additional attachments for compression and bending testing. It has functions such as digital display of test force, continuous adjustable test speed, automatic shutdown of sample breakage, and peak value retention.

Function and Features:

1. Using a high-precision, fully digital speed control system and precision reducer, the precision screw pair is driven for testing, achieving a wide range of speed adjustment during the testing process with low noise and smooth operation.

2. The universal joint adopts a cross pin structure and has a swing angle limiting function. On the one hand, it is convenient for sample clamping, ensuring the concentricity of the test, and on the other hand, it effectively eliminates the influence of irregular samples on the sensor.

3. Touch key operation mode, real-time display on LCD monitor. The display interface can display the test method selection interface, test parameter selection interface, test operation and result display interface, and curve display interface, which is convenient and fast.

4. It can adjust the fast and slow lifting of the crossbeam during sample clamping, and has protective devices for overcurrent, overvoltage, overload, etc..

5. Optional microcomputer interface, which can be connected to an external microcomputer to control the experimental process and store and print data.
