One of the best features is that it takes the guess work out of water testing. It uses a digital photometer to give you a precise readout of the test results. A photometer is an instrument for measuring the intensity of light, so the ColorQ will scan the reagent sample and that is how it gets the digital results.
This video details how the ColorQ Pro7 works and I also touch on some of the nice features of this particular test kit:
The ColorQ Pro 7 is a very versatile tester as it will check your pool or spa for all of the main test factors. So if you are a homeowner or a pool service professional it is the only test you will need. It comes with enough reagents for 144 test and 100 tablets for CYA testing.
The price range is higher than most testers mainly because of the ColorQ unit itself. Since it is a digital photometer there are some cost involved. But it comes with a one year warranty and has proven to be very durable and long lasting - some pool guys have the same unit after several years of continuous use. I like the ease of use with this kit. It is so simple anyone can use it to get accurate test results.
This video will detail how to use the ColorQ Pro 7 as I run it through all of the test factors:
I guess the main question then is how accurate is the ColorQ unit itself? After field testing it and comparing it with another digital tester you can see it is extremely accurate. I tested the Total Chlorine and the pH against the LaMotte Tracer and the results were excellent. Near the middle of the video here you will see me matching the results of the ColorQ against the Tracer. The Tracer Total Chlorine probe has a margin of error of +/- 10%, so in the video you can see both readings from the ColorQ and Tracer match up well. The Tracer has a margin of error in the pH probe of +/- 0.1 pH. The results also matched up good in the test.
So the ColorQ Pro 7 has many great features. It is easy to use, accurate and reliable. If you absorb the higher price point then I would suggest purchasing one for sure.
