High-quality components and precise control algorithms enable the device to deliver extremely accurate readings, even with a precision of 0.01 points. If KH changes too quickly between measurements, the device will repeat the test, and if the result is confirmed, it will notify the user. The aquarist can set a specific measurement difference value to widen or narrow the notification threshold.

• No central computer required.

• Advanced yet easy-to-use control.

• All Reef Factory devices are controlled and displayed in the same application.

• WiFi connectivity and smart reef system management.

Alerts are sent via text message and email when KH levels fall outside the selected range or change too rapidly, either increasing or decreasing.

KH Keeper Functionality

KH Keeper takes water samples directly from the aquarium and tests alkalinity. Readings can be scheduled as frequently as every hour, up to 12 times per day. KH status is displayed in the Smart Reef application panel, alongside historical readings. Alerts are sent via text message and/or email when KH readings fall outside the selected parameters.

Additional Features

• Historical readings available from 1 day up to 1 year back.

• Uses a reagent for testing; reagent sizes available in 1 liter and 2.5 liters.

• Reagent mixing ratio: 1L reagent / 9L RO water.

• Testing sample size: 7 ml.

• 1L of reagent provides approximately 1,429 tests, with a cost of less than 0.05 cents per test.
