Vendeur: iivs_123 (812) 99.1%, Lieu où se trouve: kyustendil, kyustendil, Lieu de livraison: Americas, Europe, Numéro de l'objet: 222319726936 JBL CO₂/pH Permanent Test SetPermanent direct measurement of CO₂ and pHA special indicator replaces aquarium water and permits direct measurement of the CO₂ level in mg/l. 20-25 mg/l CO₂ 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 CO₂ level.Mode of operation: The CO₂ diffuses from the aquarium water into the air column inside the permanent test casing, and from there into the indicator liquid. As a result of the diffusing CO₂ the pH value of the indicator changes, and as a consequence its colour also changes. This is then compared on the colour scale. In this way both the CO₂ level and the pH value can be indicated.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 only ever displays the pH value created by CO₂. The displayed CO₂ level of the JBL permanent test is always correct, and is independent from any other substances which may be affecting the aquarium water.brand new without box Condition: original box missing, Type: Test Kit, Test/Treatment Parameter: CO2, Water Type: All Water Types, Brand: JBL, MPN: 2539200, Country/Region of Manufacture: Germany
