Dual-Probe Inline TDS or EC Water Meter

Compare two water-sample points on a dedicated display. These dual-probe meter options measure either TDS or electrical conductivity, letting you choose the parameter used in your monitoring routine.

✅ Compare inlet and outlet readings - Two probes provide separate measurement points in a compatible setup.

✅ Choose the parameter you need to follow - DM-1 is the TDS option, while DM-2 is the EC option.

✅ Keep a regular reading at the installation - The separate display provides a viewing point beside the monitored system.

Compare Like-for-Like Readings Over Time

A two-point arrangement can help you record changes across a compatible filter or water system. Place the probes according to the instructions and compare the same measurement type under similar conditions.

TDS and EC are different parameters, so choose the correct model rather than treating the labels as interchangeable. A reading does not establish drinking-water safety or reveal every contaminant. Follow calibration, probe and installation requirements before relying on comparisons.
