The Kh Keeper Plus by Reef Factory is a new and innovative device that measures Kh values in the marine aquarium. The unit features compact sizing, precise readings within a 0.01 range and integrates seamlessly with the Smart Reef mobile app. Compatibility with Reef Factory's intuitive app enables the user to view history, make adjustments, track analytics and monitor all aspects of the reef aquarium with ease without the need for external computers for operation. 

The unit is compact, but provides ample room for organization within. It comes with a large laboratory-grade probe and two stepper motors.
