The Level Pro LD-01N leak detection switch is an advanced, all plastic, corrosion-resistant liquid level sensor that designed to detect conductive liquids providing a SSR relay pulse alarm. 

These sensors are ideally suited for monitoring the interstitial area between double wall tanks, tank retention dikes, secondary containment sumps, and areas where process pumps and valves are utilized. The LD-01N sensor has been engineered to withstand aggressive and electrically conductive corrosive chemicals while including features designed to optimize performance and reduce maintenance.
