NFC: Data transmission via chip
The passive NFC chipThe passive NFC chip in the Scuba3s ensures wireless data transfer to an external device with an active NFC reader (e.g. smartphone). It works like putting on your debit card when shopping:
Simply hold the mobile phone close to the Scuba3s - and everything is on the device. All data records are transferred simultaneously and are immediately available in the PoolAssistant app for evaluation. A data set includes the serial number and firmware version of the device, the name and number of the method, the dates and time of the measurement, the results and the units. A cloud is also available for data storage. -
The PoolAssistant app: Quick overview always & everywhere
The PoolAssistant app helps you to evaluate the measurement results. After transfer via NFC, up to 3 users can immediately call up the data for each control parameter for a maximum of 5 pools. The app also classifies the results as diagrams for you and gives you tools for the right pool care, the appropriate chemistry and water quality. In the FAQ section, all important questions about pool water care, water hygiene or Langelier index are answered. You can also get valuable tips here. -
Light signals for instant certainty
The light signals in the Scuba3s immediately show via the coloured backlight of the display whether the measurement result "fits" or not. If the light is green, the measurement result is within the ideal measuring range and you can start having fun in the pool. If the light is red, caution is advised: The measurement result is above or below the globally accepted measurement range for safe swimming. Also when evaluating data with the PoolAssistant app, the results are classified with green and red signal colours. The app also helps you to find the cause. -
More control parameters
With 11 tests, the Scuba3s offers even more possibilities to control the water quality in the pool based on the most important ingredients. For this purpose, choose with just a few button presses: chlorine (total, free, bound), bromine, pH value, alkalinity-m, calcium hardness, cyanuric acid, active oxygen, copper and phosphate provide information on whether the water quality in the pool is correct. The measuring process is now even faster. -
New design, more functionality
Its ergonomic design remains: The Scuba3s also fits comfortably in one hand. The back is flattened so that it cuts a good figure everywhere. With the screwable battery compartment, the electronic pool tester is guaranteed waterproof and joins in every pool fun with reliable results. With 4 multifunction buttons, you can easily find your way around the user menu on the larger display accompanied by intuitive animations and icons.
