Introducing the revolutionary Smart Tester – an advanced device for testing key water parameters in marine aquariums. This fully automated and accurate tester provides instant and accurate results of the selected parameter, which are easily accessible through the Smart Reef app. With the ability to schedule measurements and easily replace reagent cartridges, the Smart tester makes monitoring tank parameters a breeze. The device is designed so that calibration is rarely performed and cleaning is automatic, offering unparalleled convenience. From now on you can not only automate the testing of the selected parameter PO4, NO3, Mg, Ca, but also, using actions that integrate the Smart tester with dosing pumps, automate the maintenance of the selected parameter at a certain level.
