Water testing is very easy with this app and the electronic water analyser from Velda. The AquaTesterPro is a water test device that measures the most important water values and sends the results via Bluetooth to the app. You will receive a complete diagnosis and advice to improve the water quality. All test results are saved in order to monitor developments of the GH, KH, pH, NO2, NO3 and more important water values.

How does it work? The new way of water testing:
1. Dip the indicator of the water analyser into the water sample.
2. Slide the indicator through the device and read the test results.
3. Download the measured water values via the app and link them to the source.
4. Find out what the parameters say about the water quality of your pond, aquarium or pool.
