Measures PO4 / NO3 / Ca / Mg / NO2/ dKH* / OLI / NH3 / I / Fe / NO3 COMP

Mastertronic is an auto tester which performs the most important water tests with a push of a button or based on defined schedules.  The ability to perform tests will yield live data and much more accurate results as water chemistry can change over time or even hours.


Dimension: 31.5 (L) x 22.5 (W) x 35.0 (H) cm

What Mastertronic tests for

Focustronic All in One App (AIO)

The dashboard of the AIO app shows the user the latest records of tests from the Mastertronic, Alkatronic and even light schedule of the Solartronic.  A simple and intuitive view of the system’s current state.

OLI Testing

OLI stands for (Organic Level Index) and is derived by Focustronic and is only available in Mastertronic.  This measures the yellowness of the water in the system and gives a trend.  When level is higher than normal, it indicates the tank may require some maintenance such as water and/or carbon change.
