The RLE Technologies SD-RO1 spot leak detector is an economical solution for detecting fluids in small, confined areas such as A/C unit drip pans. The small footprint detector is designed with polymer coated sensing probes to detect conductive fluids at a single point. The height of the probes can easily be adjusted to the desired position by simply bending them. Units can be screwed or glued to the floor or drip pan for quick installation. All components are encapsulated against moisture. The detector is powered with 24 VAC or 12-30 VDC. It has a SPDT contact rated at 1A at 24 VDC. Electrical connections are made to its 14 foot wire leads. Units are new, unused and in their original packaging. Free shipping is included.
