Photometer Pool-Lab for professional water analysis in private swimming pools and spas. With this testing device, you can quickly and accurately measure the 11 most important pool water parameters. The operation of the PoolLAB is very simple. The built-in but interchangeable cuvette allows for quick sampling by simply immersing the waterproof PoolLab (IP68) in the water. After that, the zero adjustment (only needed once per measurement series) is performed by pressing the zero button. A reagent tablet is crushed and completely dissolved in the cuvette using the plunger. After pressing the button for the corresponding parameter, the result appears on the display within seconds. The tester can connect via Bluetooth to software and/or an app on your phone. The measurement values can be saved and printed, and dosing recommendations for water care products can be entered.
