Water Absorption Tester UP-4021

Product Introduction:

UP‑4021 Water Absorption Tester is professional footwear lab testing instrument for shoe insole performance test. It places test specimen on damp base plate and carries out repeated flexing under specified pressure, simulating the in‑service movement of shoe insoles during walking.

After completing preset test cycles, the instrument measures water‑absorbing property and water‑desorption property of footwear interior materials. It adopts touch‑screen control with counting mode and timer mode, meets the test requirement of footwear manufacturers, third‑party testing laboratories and footwear material R&D institutions.

Product Highlights:

1.Simulate real walking flexing status of shoe insoles under specified pressure Test water‑absorbing property (WA) and water‑desorption property (WD) of shoe insole materials

2.Dual test modes: Counting Mode & Timer Mode, real‑time running status display

3.Automatic water supply shut‑off & automatic test stop after preset cycles or time

4.Support manual jog operation and mechanism homing function; adjustable water flow for upper water tank

5.Compact structure, stable running, easy operation for footwear material laboratory
