The Mastertronic Info and Spec Page

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).

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 b    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

Basic Philosophy

Mastertronic is a standalone machine, that together with the appropriate reagents , will completely and automatically measure and record the values. It also has the inbuilt capacity from the beginning, to further increase the measuring palette for the future. We have also adapted Mastertronic to fit fresh water requirements by adding low range for Ca and Mg, and adapted scripts for nitrate as nitrate measurement differ some in fresh and marine.

Next important after KH are the nutrients Nitrate and Phosphate. Nitrate and phosphate are very crucial for the corals health as it ́s the nutrient for the zooxanthellae, that in turn gives coral their energy. The acceptable windows for what is optimal for the coral is quite small, as these elements at the natural reef are both very stable, and also normally quite low. In a tank, we have a closed system, which struggles to mimic the nature. It doesn’t require much at all to double or halve the nutrients just over a few days, and that will have a great impact on the corals. In most cases it ́s bad for the coral with these rapid changes, but the value itself is also so crucial. So for the first time, there is a machine, Mastertronic, that takes care of these crucial parameters for you and therefore raises the level of reefing to an outstanding level!

We also added the Calcium and Magnesium measuring possibilities. Normally Ca and Mg follow the alkalinity consumption, as it takes the same amount of calcium molecules to form the skeleton as it takes the amount of carbonates (KH). So, as long as you dose carbonates and Calcium in a ratio of 1:1 then the Ca value will follow the dKH. Therefore Calcium is not necessarily needed to measure that often. And up to the present date, almost all modern dosing recipes are balanced in this way. But with that said, alkalinity is involved in bacterial processes, where for instance nitrification consumes alkalinity and denitrification does the opposite. In normal cases this has a quite small impact, but in some cases in long term, the alkalinity and Ca can drift apart, despite you dosing in a balanced way. Secondly, your recipe may not be perfectly balanced after all. Therefore we actually also recommend to measure calcium from time to time. So therefore we have added both Ca and Mg in Mastertronic, to get this measuring palette complete for you.

Our Alkatronic is superior to measure the alkalinity. But despite that we have chosen to include a KH measuring function also in Mastertronic, to make it totally complete for all customers. Its very important to understand here the difference between a high-end ph electrode based dKH value, like we do in Alkatronic, and a colorimetric method based on color change.

The ph electrode based test (like in Alkatronic) is the only way to get that high-end reading that Alkatronic has, and that you need to also get the regulatory features. So the KH part in Mastertronic is a service to make Mastertronic 100% complete and superior, but should never be instead of a pH electrode based KH test (Alkatronic). In MT the alkalinity test is limited to 1 scheduled test per day, and therefore the KH from MT will not be able to control the DT.

Mastertronic is fine tuned based on the reagents we use versus high end lab reference fluids. That means we do not mimic the manual tests color charts, neither the reagent volumes, and thats one of many reason why Mastertronic gives a superior accuracy, precision and resolution compared to the corresponding manual tests.
