Sanitary napkin absorption speed tester CSI-018H Shanghai Chengsi- operating principle of use

Sanitary napkin absorption speed tester Sanitary napkin absorption speed tester consists of
a standard test module, an arc specimen holder, an automatic dosing device and an automatic timer.

Detection principle: sanitary napkin sticks to the arc specimen holder of the absorption speed test race, the standard test module is placed in the absorption area of the sample surface, the automatic dosing device adds a certain volume of standard synthetic test liquid to the standard test module, and the timer records the time when the sanitary napkin completely absorbs the standard synthetic test solution, indicating its absorption speed
.
