LBT-ZF-631 Protective Clothing Acid-Resistant Performance Tester

It is primarily used to evaluate the acid- and alkali‑resistant performance of breathable acid‑ and alkali‑resistant protective garments by allowing a test solution to flow over the sample surface, assessing whether the solution is retained or penetrates the material, and calculating the acid‑ and alkali‑resistance efficiency index.
