- A special indicator instead of aquarium water permits direct measurement of the CO level in mg/l.
- 20 25 mg/l CO is ideal.
- Replace the indicator only every 3-4 weeks = lasts a total of 9-12 months.
- Indicates the pH value (6.4 7.8) in addition to the CO level.
- Mode of operation: The CO diffuses from the aquarium water into the air column within the permanent test casing and from there into the indicator liquid. As a result of the diffusing CO the pH value of the indicator changes and consequently also its colour, which is then compared on the colour scale. In this way the CO level and also the pH value can be read.
- If however the pH value in the aquarium has been influenced by other factors (peat, pH-Minus), then the indicator of the JBL permanent test cannot react because these acids cannot diffuse into the indicator via the air column. The indicator always merely displays the pH value which is reached due to CO.
- The displayed CO level of the JBL permanent test is always correct, independent of any substances in the aquarium waters that are affecting the water.
