Dennerle CO2 long-term test Correct

Description

The CO₂ long term test Correct + pH enables you to control the CO₂ content of your aquarium in a save and exact way. The level of CO₂ in the aquarium can be read directly from the six-colour scale in milligrams per litre. This provides an absolutely simple and reliable means of setting the correct CO₂ supply level.

Conventional long-term CO₂ tests are filled with a mixture of aquarium water and indicator. This involves various disadvantages, one being that the acids which are present in all aquarium waters (e.g. humic acids, nitrate, etc.) can lead to incorrect test results. The DENNERLE CO₂ long-term test Correct employs a ready-to-use special CO₂ indicator which is used on its own, rather than in a mixture with aquarium water.

Features

• Simplicity – No additional measurement of carbonate hardness is necessary. Only a single colour-matching scale is required.
• Safety – The CO₂ long-term test Correct +pH indicates the CO₂ content correctly at all times – independently of other acids in the aquarium water (e.g. humic acids).
• Accuracy – The CO₂ long-term test Correct allows direct determination of the CO₂ content in millilgrams per litre – avoiding the need for additional water measurements and the laborious practice of converting values in tables.
