This test device meets the requirements of UL-1581 heating deformation test, and is used to measure the deformation test of the wire under a certain temperature and load. Need to be used in conjunction with the aging box. The device is equipped with a tray, which can be filled with weights of corresponding weight as required.

Main parameters:
1. Diameter of the upper end of the pressure rod: Φ19mm
2. Diameter of the lower end of the pressure rod: Φ9.5mm
3. Total weight of pressure rod: 250g
4. Test station: 3 groups
5. Load weights: 3 each of 50g, 100g, 200g, and 300g.
