s-pH007 pH sensor

The LinkSens S-pH007 is an industrial-grade digital pH sensor based on electrochemical measurement principles. It determines pH value through a linear relationship established between a glass measuring electrode that responds to changes in the medium's pH and a stable reference electrode. Built around an industrial-grade electrode core, the S-pH007 supports a wide range of interchangeable probe types - including versions for ultrapure water, high-temperature, low-temperature, desulfurization/denitrification (FGD/SNCR) process water, and hydrofluoric acid-resistant applications. The sensor integrates automatic temperature compensation and digital signal conversion, and communicates over RS485 using the standard Modbus RTU protocol for straightforward integration with virtually any industrial network or monitoring terminal.

Why we like the S-pH007: it's built to be a “fit-and-forget” sensor for demanding field conditions - the all-in-one probe design means there's no separate transmitter to wire up, no glass bulb to babysit in a fragile housing, and the IP68-rated body shrugs off submersion, washdown, and humid plant environments alike. For OEMs and system integrators, the standard 3/4" thread on both ends and Modbus RTU output make it a near drop-in replacement for most existing pH probe sockets, which keeps integration time and engineering cost low.
