Pneumercator ES825-200XF Solid-State Discriminating Leak Sensor, Polysulfone Body - (SKU: ES825-200XF) is an advanced electronic leak sensor for regulated tank containment and environmental compliance. This non-moving, solid-state sensor detects liquid presence and distinguishes between fuel (product) and water leaks using both electro-optical and conductivity principles.

Discriminates Between Product and Water: Delivers fast response for hydrocarbons or water. Electro-optical detection senses any liquid presence, while a conductivity probe confirms water, enabling environmental controls and alarms to distinguish leak source for compliance and action. Ideal for critical containment, sumps, dispenser pans, and double-wall tank interstitial spaces.

Extended Temperature, Fault Monitoring, Rugged Build: All wetted parts are FEP Teflon and polysulfone, enabling chemical resistance to fuels and solvents. FEP-jacketed, 25' (7.6 m) 22 AWG, 3-conductor cable with fault detection supports field runs to 4000 feet when used with Pneumercator LC2000 and TMS series. Wide temperature range of –65°F to +185°F (–55°C to +85°C).

Applications: Use for tank sumps, piping sumps, annular spaces, and dispenser pans requiring distinction of water vs. hydrocarbon leaks with industrial reliability, even in extreme climates and hazardous locations.
