Water Quality Monitoring
EvaraTDS
Water quality at a glance
Inline TDS monitoring at RO outlets, running 24×7 with temperature-compensated readings.
Some specifications for EvaraTDS are still being finalised and are marked accordingly below.
The problem
Why this exists.
Water quality is usually checked with occasional manual sampling, if at all. Users have no continuous visibility into whether their water is safe or within acceptable limits, and contamination or drift goes unnoticed until it becomes a problem.
The principle
How it actually works.
Sense
Inline sensors capture TDS and temperature continuously through the monitoring cycle.
Compensate
Local processing corrects for temperature, which otherwise skews conductivity readings.
Filter
A median across multiple readings suppresses sensor noise and transient spikes.
Stream
Processed values are transmitted for storage, live trends and out-of-range alerts.

How it works
EvaraTDS sits inline at the RO storage tank and measures total dissolved solids and temperature continuously. Readings are temperature-compensated and median-filtered on-device before being streamed to the cloud for trends and alerts.
Retrofit-first
Installs onto infrastructure you already own. No pipe cutting, no civil work, no permits.
