Dennerle Carbo Test Precision Small

Long-term CO2 test with pH measurement.
Long-term tests are made from high-quality crystal glass and are suitable for permanent, direct measurement of CO2 in the aquarium. The white inner tube makes it easy to recognise the colour of the indicator liquid at a glance, whatever the background. Thanks to its compact spherical shape, the test reacts quickly and reliably to fluctuations in CO2 in the aquarium.

As long as there are no other substances influencing the pH value in the water (e.g. humic acids, nitrates, pH minus preparations), you can also measure the pH value in the aquarium with the Carbo Test Precision (KH test required).
