CO2 Indicator Orb Checker

The Orb Checker is an elegant and unobtrusive CO2 continuous test made of glass for permanent monitoring of the carbon dioxide content.

The ball is filled with a few drops of the test liquid supplied and then carefully attached upside down to a pane in the aquarium (below the water level). Please ensure that the test liquid is not spilled and that there is enough air in the glass so that the water in the aquarium does not come into direct contact with the test liquid.

After about an hour, you can compare the color of the test liquid with the color scale and read the corresponding pH value. The test liquid is set for a KH 4 and should be renewed every 4-6 weeks.

Delivery includes 100ml test liquid, color scale and suction cup for attachment. Diameter of the ball approx. 3cm
