## Description

Product description Developed in Germany for the US market ACCURATE - Level 1 (L1) : The highest accuracy and repeatability performance level of a water testing device. Under laboratory conditions, the instrument-/reagent- and user related tolerances can be up to +/- 10 % of the actual value. For the parameter "pH" a tolerance of up to +/- pH 0.10 applies. How PoolWaterLAB works - Collect a water sample and fill the measuring chamber of the PoolWaterLAB photometer. - Add the required reagent — it reacts react with the target chemical compound in the water. - PoolWaterLAB then analyzes the treated sample and displays the concentration as a precise digital ppm result.

Review: An important tool if you are serious about taking care of a swimming pool. - I really like the pool, Lab 2.0 It works as advertised. There are a couple of features I wish it had. One is that you cannot exit the zero mode and go direct to testing. I found at times I inadvertently put the wrong chemical reagent in line for testing, and the machine had been already zeroed. As such I had to turn it off, pour out my reagents and start all over again. The second one is that the instruction manual is written in pictures, but wow, being brief leaves out important language that would be helpful to understand what they’re trying to teflect, especially when it comes to a double testing component within a single test, procedure thing done one right after the other in the same test chamber. Frustrating. Nonetheless, it’s a good tool and also dors a great job once you understand what they’re trying to tell you to do.
Review: Gentlemen, do not buy this, this is useless under any circumstances - I have tried everything with this, I have sensors all over the pool and no sensor comes close to these measurements. This does not provide a single correct measurement, neither from the pool water nor from the faucet in the house, I have 3 types of water on my property, that's why I bought it looking for a faster system at hand that would give me at least 3 measurements at the same time. REALLY A WASTE OF MONEY, IT WILL END UP IN A BOX IN MY GARAGE, IT DOES NOT WORK, DO NOT SPEND YOUR MONEY ON THIS DEVICE.

## Features

- NOT FOR EVERYONE — PLEASE READ FIRST If you're looking for a simple, “marketing-style” pool tester with basic strips and minimal setup, this device is not for you. Our photometer is built for users who are ready to move with the times, embrace modern precision technology, and spend a little time learning how the device works. Once you understand the basics, the testing process becomes incredibly easy, fast, and consistently accurate.
- PROFESSIONAL-GRADE DIGITAL WATER TESTING — NO GUESSWORK Get lab-accurate chemical analysis every time — PoolWaterLAB uses advanced photometric technology to deliver precise digital results instead of subjective color matching.
- PRECISE FREE CHLORINE & CYANURIC ACID (CYA) CONTROL Know exactly how effective your chlorine really is. Accurate CYA measurement prevents “chlorine lock” and helps you maintain proper sanitizer levels for safe, clear water.
- STOP WASTING CHLORINE & SHOCK TREATMENTS Most pool problems come from incorrect chlorine-to-CYA balance. With precise digital readings, you avoid overdosing, underdosing, and unnecessary chemical costs.
- SMART TRACKING VIA APP — SEE THE FULL PICTURE Sync via Bluetooth/WiFi to monitor trends, track chlorine stability, and make data-driven adjustments instead of reacting to cloudy water.
- COMPLETE WATER CONTROL — BEYOND TEST STRIPS Measure multiple key parameters including pH, Total Chlorine, Alkalinity, Calcium Hardness and more — with consistent, repeatable accuracy trusted by serious pool owners and pros.

*by N***A on September 22, 2023*

Complete starter kit. My personal advice to anyone who decides to buy it is to spend a little time studying the manual, after the third use I realized that it is very easy to use, despite the fact that it is a professional device, it has everything you need even much more. 👍
