Model: RD-PH

pH Sensor for Water

pH sensor for water, 0–14 pH, ±0.02 pH, for environmental monitoring, aquaculture and laboratory use.

The RD-PH is a pH sensor for water. It gives stable, fast pH readings for environmental monitoring, aquaculture and laboratory use. Its robust design is easy to install and maintain, so it suits continuous water quality assessment. It connects to a SpaceEcho station and reports to EchoCloud.

Combining water quality sensors

These three probes measure different parameters, so they are used together rather than instead of each other.
