KH KEEPER PLUS – Smart Wi-Fi Alkalinity Analyzer for Continuous KH Monitoring in Marine Aquariums
Reef Factory KH Keeper Plus is an advanced electronic device that automatically and precisely monitors alkalinity (KH) in marine aquariums using pH electrode titration technology. With up to 12 programmable tests per day, it provides real-time KH tracking and stores results in the Smart Reef cloud system, accessible via smartphone, tablet, or browser.
The unit draws aquarium water using built-in pumps, adds a diluted reagent, and performs an automated KH test. If the alkalinity value falls outside your predefined range or changes drastically, the system repeats the test and sends immediate alerts via SMS, push notification, or email.
Visual feedback is given through an LED status indicator: green means values are within range, red signals an issue, and blue indicates an ongoing measurement. When combined with Reef Factory dosing pumps (sold separately), KH Keeper Plus can automatically correct KH levels, providing a fully automated alkalinity management system.
