Product Specification

Description:

    The pHionics STs SeriesDissolved Oxygen 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 using pHionics patented pHiConnSystem, saving frustration and money.
