Capabilities

Automatic EC control

Doses A+B when EC falls below target, then waits 30 seconds to mix before measuring again.

Careful pH control

Adds acid only after a high pH is confirmed 10 times — no overdosing on noisy readings.

The right order

Never adds nutrients while pH is high; pH is always corrected first.

Flow and temperature checks

Confirms water is actually flowing and tracks water temperature.

Mixing schedules

Set when mixing rounds run.

Front-panel display

An LCD shows targets and live values right at the tank.

Connections

The device reads the field, drives equipment, and sends data to the cloud.
