Description
The ST-711 an inline single-channel ORP sensor that is specifically designed to simplify installation, calibration and operation in process, industrial, waste and cooling water applications. This sensor offers an embedded transmitter and can be utilized in both 4–20mA or RS-485 Modbus formats. When used in RS-485 format, the ST-711 also provides a temperature output signal. These features dramatically improve application possibilities allowing the ST-711 to be directly connected to most OEM controller, PLC or DCS systems.
The ST-711 has an oversized platinum disk for ORP that increases resistance to highly turbid waters and contamination. The enlarged salt bridge design with large junction capacity also ensures a long sensor life with minimal maintenance. This device is ideally suited for “hard-to-measure” waters where conventional ORP sensors would otherwise fail or require high maintenance costs. The ST-711 does NOT require electrode change-out or Potassium Chloride (KCl) re-fill, and is designed to be used until the end of life and then completely swapped out.

Reverse Osmosis & Desalination
Reverse Osmosis (RO) desalination is a cutting-edge water treatment process. It removes dissolved salts, minerals, and contaminants by forcing water through semi-permeable membranes under high pressure. RO has become a critical solution for transforming seawater and brackish sources into usable water. Applications include municipal, industrial, and commercial grade systems.
Pyxis Lab delivers advanced inline sensor technology, smart analytics, and plug-and-play monitoring systems. Designed specifically for the challenges of RO desalination, our innovative solutions empower operators with real-time insights. In addition to reliable data to drive system efficiency, protect assets, and achieve superior water quality at every stage of the process.
