Photometric analysis and diagnosis of water values with your smartphone. *** TO USE THIS APP YOU WILL NEED THE JBL PROSCAN SET AND THE ENCLOSED PROSCAN COLORCARD *** • Fast readout, precise analysis, innovative colour detection technology • Parallel analysis of the most important water values for the aquarium, pond and other water with the help of your smartphone • With detailed evaluations of the individual water parameters incl. background - knowledge and recommendations for action in the app • Unlimited use of the app for recording the 7 most important water values with display of the last measurement - even without a myJBL profile • With your own myJBL profile – storage of analyses to compare your last five measurements • Creation of several profiles for the waters (aquarium / pond / water) • Scan reminders individually adjustable (days, weeks, time) • Simultaneous use of different devices using the same myJBL profile possible Here's how it works: Start the app and experience a fast and precise analysis with innovative technology for analysing water values in aquariums - to date only available from JBL. Use the specially calibrated JBL PROSCAN ColorCard enclosed and follow the instructions in the app. Under “Analyses” you can manage your aquariums and ponds and compare the measurements in a graph. You can now access this data from anywhere in the world via your myJBL profile - even without a smartphone. Without the myJBL profile, the last measurement is only locally saved in the app. The measurement and evaluation with recommendations for action is also possible here without restrictions. The following water types are available in the app: "Aquarium", "Pond" and "Water". If you select aquarium and water, the app calculates the current CO2 content from the pH and KH values measured with the app as a bonus. Depending on the values measured and the type of water, you will receive specific recommendations for action and info on which JBL products will help you to re-establish the ideal/optimal water values. In “Water values”, the app gives you a simple overview of the results without any notes and recommendations. The myJBL profile provides you with numerous additional features such as reminders, tips and graphical evaluations. Important notes: • The analysis strip continues to react constantly. A strip may only be scanned once. Repeated or late scanning will result in different values. The colour fields darken from as early as 70 seconds after immersion. • Excess water on the test strips causes reflections. The surface must not be reflective. A sheet of kitchen roll is the ideal underlay for use. • Do not shake the test strip in the air. This causes cross-reactions of the individual measuring fields. Solution: tap the strip at the side of the sheet of kitchen roll. • Choose bright daylight or artificial light to carry out the analysis strip reading using the ColorCard. Avoid direct sunlight, flashlight or direct light sources, as these can create shadows that disturb the reading. • Depending on the provider, additional charges may apply when connecting to the internet. • To read the ColorCard accurately, always hold the smartphone vertically above the ColorCard.

I used now two stripes and the app write me error messages... ### 5/5 — Happy *2025-01-28, version 4.0.5* Happy with the product once I learnt how to use correctly. I.e. put the bit that you hold at the bottom of the card. ### 1/5 — Log out! *2025-01-25* Ужасно! Каждый день выходит из аккаунта и приходится повторно ввести логин и пароль! Почините! Про качество тестов скажу 5 с минусом. От профессионалов часто слышу что тест полоски ерунда. Нет, тест полоски удобно и точно. Но нужно ровно минуту держать, 15-30 секунд дольше и точности уже не будет. Так что не смотря на низкую оценку самими тестами доволен. Сравнивал с реагентами, расхождения минимальные. **Developer response:** Hi Igor, please contact us on www.jbl.de/support regarding your issue. We will have a look on it and find a solution! ### 5/5 — Den Teststreifen richtig auf die Farbkarte legen, dann klappt es auch mit der Messung *2024-12-30* Auf der ColorCard sind Hinweise für oben "top" und unten "bottom" angegeben. Nimmt man nun den Teststreifen in die Hand, wird automatisch zur Seite "bottom" gegriffen. Es ist die Seite, die unten keine Analysefelder auf dem Streifen hat. "top" hat die Analysefelder bis zum Rand. Sollte eine Fehlermeldung in der App erscheinen, wurde der Analysestreifen verdreht auf die ColorCard gelegt. Korrigieren Sie einfach die Positionierung. **Developer response:** Hi BusybeeST, danke für dein Feedback. Oft sind es nur Kleinigkeiten, wie beispielsweise die Positionierung, welche das Ergebnis beeinflussen. :-) ### 1/5 — Nul *2024-12-28* 20 balle la boîte de test et impossible de scanner. Allez à la concurrence vraiment le scan marche au moins. **Developer response:** Hi sspaari, thanks for your feedback. It is often only small things that influence the result. Please contact us on www.jbl.de/support regarding your issue. We will have a look on it and find a solution! ### 2/5 — Buggy *2024-12-20, version 4.0.5* There’s a bug where, if it loses connection, even for a second, you need to login again. Unless you have an absolutely rock-solid internet connection, expect having to re-login over and over and over and over…. ### 2/5 — Dysfonctionnement *2024-11-09* Bonjour, J’utilise l’application depuis plusieurs mois et au début ça allait très bien puis elle me marque que la bandelette est mal positionnée sur la carte alors que c’est bien centré… Combien de bandelettes j’ai jeté pour recommencer et avoir les données archivées Vraiment pas cool alors que le concept est génial Ce serait sympa d’avoir un remboursement mais ce sera jamais fait **Developer response:** Hi Kivala31011, please contact us on www.jbl.de/support regarding your issue. We will have a look on it and find a solution! ### 1/5 — Arnaque *2024-10-18* Cela ne fonctionne pas avec iPhone 13 Pro **Developer response:** Hi Arnaque, please contact us on www.jbl.de/support regarding your issue. We will have a look on it and find a solution! ### 5/5 — Super Prinzip *2024-09-03* Ihr solltet es einfach mal ausprobieren. Für 20 euro inkl. 25 teststreifen und app macht man nichts falsch. Sehr gut ist: -speichern der Messungen -kritische Werte werden erklärt inkl. Hilfe für Beseitigen der Probleme -gerade für Anfänger sehr gut zu bedienen Bis gerade hatte ich einige Werte garnicht im Blick. Und die Referenzkarte zum analysieren ist wasserfest. Eventuell sollt man diese auch nachbestellen können und mindestens Jährlich tauschen und dunkel geschützt aufbewahren! Nochwas , was ich ändern würde: nach der messung sollte eine automatische speicherung erfolgen. Ich habe das „speichern“ drücken zweimal verpasst und die werte sind dann weg. Nachträgliches löschen sollte möglich sein. **Developer response:** Hallo Mir33241, danke für deine Bewertung. Deine Wünsche haben wir vermerkt! ### 3/5 — Ansich gute Idee aber bugs nerven *2024-08-28* 1. Mit meiner ersten Registrierung kam die App nicht klar, auf der Homepage ging es immer Erst als ich einen 2. Account gemacht habe ging, irgendwas war nicht sauber. 2. die App loggt sich ständig aus , vor allem wenn er gerade eine Messung macht und das Handy ausersehen gesperrt wurde kommt dann der login screen so das dann ein streifen wertlos ist. Das nervt extrem Mit freundlichen Grüßen **Developer response:** Hallo Blizzord, vielen Dank für deine Rückmeldung. Kannst du uns sagen, seit wann circa das Problem des erneuten Logins besteht? Gerne möchten wir dies nachprüfen. Ein Re-Scan ist bewusst ausgeschlossen, da der Teststreifen nach Abschluss der 60 Sek binnen 10 Sekunden erfasst werden muss. Andernfalls stimmen die Werte nicht mehr, da der Teststreifen weiter reagiert. Gerne kannst du dich unter www.jbl.de/support mit einem Ticket melden, damit wir das Problem individuell nachprüfen können. ## Frequently asked questions about JBL PROSCAN ### What is the JBL PROSCAN app?
