Product Specification

Description:

    The pHionics STs SeriespH is a dual-output sensor that pairs with a datalogger or RTU for real-time water quality monitoring.  A narrow diameter allows the STs Series to go where other sensors cannot while a durable, chemical-resistant housing ensures many years in-use.  

    All parts, including the cable, are easily replaceable without tools usingpHionicspatentedpHiConnSystem, saving frustration and money.

    In addition, isolation, differential amplification, and shielding ensure a strong signal with high signal-noise ratios, all while remaining low-power.

    These features make our pH sensor well-suited for applications such as groundwater monitoring, wastewater treatment, aquaculture, pollution monitoring, etc.
