Dragino DR-PH01 Water pH Probe
The Dragino DR-PH01 is an industrial-grade water pH probe designed for continuous monitoring of water acidity and alkalinity across agricultural, industrial, and environmental applications. Featuring a double salt bridge reference electrode, automatic temperature compensation, and an IP68 waterproof construction, the DR-PH01 delivers stable, accurate pH measurements in demanding environments.
This probe requires the Dragino WQS-LB LoRaWAN® Water Quality Sensor Converter (sold separately), which supports up to three water quality probes—including pH, EC, dissolved oxygen (DO), ORP, and turbidity (TS). Once connected, measurements are transmitted wirelessly via LoRaWAN® and integrate seamlessly with Microclimates EnvOS® for real-time monitoring, historical trending, alerts, dashboards, and automation.
