Water analysis using your smartphone - the new generation
Note: The test strips are only intended for one measurement each. A repeated scan of the strip leads to different values, since the strip goes on reacting indefinitely.
During the analyses "Aquarium Freshwater" and "Water" the current CO2 content in the water is calculated as an additional bonus. Depending on the analysis results in the sections “Aquarium Freshwater” and “Garden Pond” individualized recommendations and hints are given as to which JBL products can help to set the ideal/optimal water values.
How accurate is this measurement method?
Since smartphones provide an automatic white balance, the color reading is more accurate than if we compare colors with our eyes! If the test is performed correctly, the result is absolutely reliable. With the nitrite result, experience shows that an additional drop test measurement (with JBL PROAQUATEST NO2 Nitrite) is a good idea if the JBL ProScan result does NOT show 0, as this value needs to be 100% reliable (nitrite is fatally toxic for fish from 0.4 mg/l).
Possible errors during use:
When removing the test strip from the water, do not shake it vertically, as the wet colors will then run into the other color fields. It needs to be drained off HORIZONALLY and carefully. Without dripping off, the drops on the color fields reflect the light too strongly and lead to inaccurate results. Photographing the test strip on the color chart should ideally be done in daylight. But even more important is that the incidence of light is uniform and does not show partial shadows and partial sunlight. If this were the case, the colors on the color chart would be illuminated differently.
