The G373 Liquid Sliding Penetration Comprehensive Performance Tester is a precision instrument designed to evaluate the liquid penetration performance of diapers and hygienic non-woven fabrics. It accurately measures strike-through, back-seepage, and overall penetration efficiency, simulating real-world liquid exposure to assess product quality and reproducibility. The tester integrates a solenoid-controlled funnel, adjustable sample holder, and automated data acquisition for precise and repeatable results.

Application

The tester is widely used in:

(1) Diaper and hygiene product manufacturing for evaluating absorbency, strike-through, and backflow resistance

(2) Non-woven fabric R&D for assessing liquid penetration properties of sanitary materials

(3) Quality control laboratories for verifying batch-to-batch performance of diapers and pads

(4) Third-party testing institutions for product performance certification

(5) Regulatory and supervisory agencies for monitoring compliance with hygiene and safety standards
