Focustronic Mastertronic

Mastertronic (MT) is the latest addition to our product range for automated water testing equipment. MT will be able to communicate with our other products such as Alkatronic, Dosetronic, Solartronic (patented dynamic lighting fixture), and Powertronic (smart power strip). Above photos are for reference. We are in process of making the tooling to resemble the generic design of Alkatronic with door opening for access with rounded corners.

Basic Specification:

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

  • High Precision Stepper and DC Pumps

  • State of the art colorimetric photosensor

  • Simple to use iOS and Android App (Wifi). Focustronic App (all in one)

  • Communicate with Alkatronic/Dosetronic/Solartronic/Powertronic: local wifi via router

  • Nitrate (NO3)Accuracy / Precision (+/-) : 0.5 mg/l / 0.1 mg/l

  • Phosphate (PO4)Accuracy / Precision (+/-): 0.01 mg/l / 0.005 mg/l

  • Magnesium (Mg) Accuracy / Precision (+/-): 20 mg/l / 20 mg/l

  • Calcium (Ca) Accuracy / Precision (+/-): 6 mg/l / 6 mg/l

  • Alkalinity (dKH) Accuracy / Precision (+/-) 0.1 dKH / 0.05 dKH

  • OLI – is our own derived parameter which measure the organic matter in water. Can indicate when users should run or replace carbon

  • Ammonia (NH3) Accuracy / Precision (+/-) 0.01 mg/l / 0.01 mg/l

  • Iodine (I)* Accuracy / Precision (+/-) 0.01 mg/l / 0.01 mg/l

  • Iron (Fe)* Accuracy / Precision (+/-) 0.005 mg/l / 0.005 mg/l

  • Nitrate Compensation

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

Feature Highlights:

  • Ability to auto adjust Ca and Mg dosing levels in Dosetronic as sometimes even balanced dosing will require adjustments. This will be done via ODA.

  • MT will pass test data to Solartronic and user can select auto intensity adjustment based on either PO4 or NO3. This will be a unique feature in our product range and not available with any other lighting brands.

  • When Powertronic is released, we will include features to trigger on/off or even timer for the sockets. For example, algea reactor light, currently running 12 hours. If nutrient (ie: PO4) gets too low, reduce by 10% to 11 hours).

  • For ULNS, dosing PO4 and NO3 can also be regulated via Dosetronic.

  • Expect new feature in Dosetronic for daily feeding and could also be adjusted based on data.

  • Considering offering an autofeeder for dry fish food. Lower nutrients will auto increase feeding frequency


Specifications may vary in end product upon release.

Alkalinity test is limited to 1 test per day and will not carry out actions like in Alkatronic. For multiple tests, best to use Alkatronic

Iron test in marine water should yield a 0 mg/l or very close to 0 mg/l.

Ammonia test in Mastertronic is focused in freshwater system. You can still test for ammonia but this may only be needed for new setup.

Nitrate Compensation is a NO3 test that takes NO2 into account. This is useful and provide a true NO3 reading if your low and/or have high NO2 values. When in doubt, it is best to use this mode for all NO3 tests.
