Product Details
Low Temperature Tensile Tester
Brief Introduction
The ZONSKY Low-Temperature Tensile Tester measures how well wires, cables, and insulation sheaths maintain their mechanical strength and flexibility in freezing environments.
Highlights / Outstanding Features / Characteristics
- Subzero Performance Testing: Evaluates material integrity, stretching capabilities, and cold-weather resistance.
- Key Metrics Recorded: Accurately measures yield strength, ultimate tensile strength, and ductility (flexibility).
- Versatile Applications: Ideal for testing wires, cables, rubber, plastics, and protective insulating jackets.
- System Requirement: Note: This instrument requires an external low-temperature chamber to handle subzero cooling.

Equipment structure
1. Control and Stretching Parts
- The machine is divided into two sections: a control panel and a stretching unit.
- During testing, the stretching unit is placed inside the low-temperature chamber, while the control panel remains outside.
2. Clamps & Fixtures
- The stretching device contains two sets of clamps: one fixed and one movable.
- The fixed clamps hold the samples in place, while the movable clamps apply the tensile force.
