The Georg Fischer Signet ORP Sensor 3-2725-60 is a high-performance oxidation-reduction
potential (ORP) electrode designed for accurate and reliable water quality monitoring in
industrial process applications. Engineered by Georg Fischer Signet, this flat-surface ORP
sensor features advanced DryLoc® connector technology and a patented reference electrode
design for stable measurements, long service life, and excellent chemical compatibility.
The sensor is manufactured with a durable Ryton® (PPS) body and platinum sensing element,
making it suitable for harsh industrial environments and aggressive process media. Its flat-tip
design helps resist fouling and ensures reliable ORP measurement in applications involving
contaminated liquids, suspended solids, and difficult process conditions.
The 3-2725-60 ORP sensor is compatible with Georg Fischer Signet 2750 and 2760 sensor
electronics and integrates seamlessly with Signet transmitters including the 8900, 9900, and
9950 series. It is widely used in water treatment, chemical processing, cooling towers, and
industrial process automation systems.
