Junkosha Leak Detection System
Early leak detection is essential in various industrial fields for minimizing serious accidents, environmental pollution, and loss of precious fuel resources that leaking fluid can cause.
Junkosha uses the advanced processing technologies we’ve developed over many years to manufacture leak detection systems with sensors using fluoropolymers with outstanding weathering resistance, chemical resistance, and water resistance.
