The Focustronic Mastertronic is a standalone automated water testing machine designed for saltwater aquariums. It accurately measures critical parameters including nitrates, phosphates, magnesium, calcium, alkalinity, and organic matter using advanced colorimetric technology. This system eliminates the guesswork of manual testing by handling the process automatically while recording data for trend analysis.

Equipped with high precision stepper and DC pumps along with a state-of-the-art colorimetric photosensor, this device ensures reliable readings within tight tolerances. Users can control and monitor the unit via an easy-to-use iOS or Android app with WiFi connectivity for cloud access. It features seamless wireless communication with other Focustronic products like Alkatronic, Dosetronic, Solartronic, Powertronic, and smart sockets to automate dosing and equipment control based on live measurements.

This automated solution is best for advanced reef keepers who demand precise water chemistry management without the daily hassle of manual testing kits. It suits hobbyists seeking a fully integrated ecosystem where test results directly trigger corrective actions through compatible dosing controllers and power outlets. Please note that specific test kit reagents are sold separately and a smartphone running iOS or Android is required for operation.
