The SpillGuard leak-recognition system (photo) instantly alerts users when a leak is detected. This FM-approved technology is placed within the sump of a spill-containment device, or near the equipment to be monitored, and alerts users with an audible and visual alarm for a minimum of 24 h when contact is made with a liquid. Designed for use with all essential and common liquid hazardous substances, the explosion-proof SpillGuard features intelligent sensor technology in a highly resistant, electrically conductive housing. It is suitable for use at temperatures from 32 to 104°F, and has a red LED light to indicate that the unit is operating safely. It is ideal for use with containers and sumps of all sizes and types, as well as along pipelines, next to heating or cooling systems, beside hydraulic equipment, near industrial washing machines, adjacent to pump stations or anywhere that liquids are used or stored. — Denios Inc., Louisville, Ky.
