The Panasonic SUNX EX-F61-PN leak detection sensor utilizes capillarity to reliably detect even the smallest leaks of liquid and viscous substances. Its compact size and PFA enclosure provide excellent chemical resistance, making it suitable for environments with exposure to chemicals like sulfuric acid, hydrochloric acid, or ammonia. The sensor's design simplifies installation and maintenance, requiring only a simple wipe-down for reset and eliminating the need for component replacement. It's a robust and efficient solution for industrial leak detection applications.
