Pyxis Lab ST-710 Series Industrial pH & ORP Sensors

Overview

The Pyxis ST-710 series of pH and pH/ORP combined sensors are specifically designed to simplify installation, calibration and in-use operation in process water, industrial water, wastewater and cooling water applications. These sensors are uniquely designed to offer an embedded transmitter and can be utilized in both 4-20mA or RS-485 Modbus formats. When utilized in RS-485 Modbus format, these sensors also provide a temperature output signal. These features dramatically improve application possibilities allowing the ST-710 series of sensors to be directly connected to most OEM micro-processor- based controllers, PLC’s and Distributed Control Systems. The ST-710 series oversized platinum disk for ORP and the flat pH bubble sensing elements increase their resistance to highly turbid waters and contamination. The enlarged salt bridge design with large junction capacity also ensures a significantly longer sensor life with minimal maintenance. These devices are ideally suited for hard to measure waters where conventional pH & ORP sensors would have otherwise failed or required high maintenance costs. The ST-710 series of sensors do not require electrode change out or Potassium Chloride (KCl) re-fill and are designed to be used until end of life and completely swapped out. Each sensor offers a six-foot cable 7-Pin quick adapter as well as a 1.5-foot flying lead wire with 7-pin adapter for rapid installation and replacement. The ST-710 series are provided with the ST-001 Pyxis standard ¾” NPT-CPVC installation Tee for in-line flow applications but may also be installed in submersed applications using the MA-102S Submersion Adapter Kit. Additionally, larger pipe size installation Tee’s are available from Pyxis Lab.

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.
