Is Digital Water Testing Accurate?

So are pool Digital Water Testers Accurate? The answer is yes, as long as they are calibrated correctly and it is a reliable brand. In this video I will show you results from various digital testers and match them against each other.

The benefits of a digital water tester are that you get spot on results and they can preform tests the reagents cannot, such as Total dissolved Solids (TDS), Salinity (Salt level) and ORP. Most have a small margin of error +/- or 1% in most cases. I use them on my pool route and as a homeowner you can benefit also from certain digital testers.

The number one tester I would suggest if you are a homeowner and have a salt pool is a Salinity tester. That way you will know the salt level and can maintain your pool properly. Even if your salt system displays the Salinity level – that reading can be effected by a dirty salt cell and can give you a false low salt reading. In that case you may add salt when it is not needed and raise the salt level to levels that are not recommended adversely affecting your pool. Simply using a digital Salinity tester can eliminate that error.

A pH digital tester can be handy also but the reagent test is cheaper and accurate so I would only recommend that one for a pool service professional looking to compare readings – especially at a commercial pool account to make sure the pH is within range of the local Health Department regulations. This can be very helpful for hotel and apartment spas where the pH tends to drift down rapidly. The digital pH reading is the most accurate one and some Health Departments use digital testers themselves also.

ORP is a great way to test if the water is at the safest level to swim in. Again, if you service commercial pools this would be a great digital tester to invest in. If you are a homeowner and your child gets frequent ear infections or has a lower immune system – an ORP tester would be a good thing to have. That way before the pool is used you can see if the level is high enough, 650 or higher, to insure the fastest kill rate against bacteria and viruses. To learn more about ORP see the video link below.

I used a combination of the HACH and the LaMotte Tracer testers to verify the results. I also used the Color Q Pro7 and a Pentair automation to triplicate some test results. As you can see from the video the results lined up with each other in all the testing. There are many other brands of digital testing, these are the two that my local supplier carry and both brands are very good.

Bottom line, digital testing is accurate and reliable.

I have many videos on digital testing and to learn more see the links below:

it's such a pleasure to watch ur videos. very informative! thanks again!

[IEraiderfan]

Thanks for your series of videos very educating.

I use the myron 6p and check the calibration on a weekly basis and keep the bulb wet with pH storage solution. There is also a myron 9p that does calcium alk and lsi.

[emoney]

Water sample from the very top of the water line. Lol 😂

[AereForst]

Which of the three would you recommend?

[whitemok]

so do like the hach or the tracer better?

There is a pattern to the tone of your speech. You start every sentence low and end high. Constantly. Without fail.

I love the color Q but the seem to break easy. Is there anyone who can repair them? Lamottes on my advise is to clean the cell with window cleaner and that doesn't help. The error message keeps showing up. Help, it's only 6 months old.

[ccrforever]

having trouble with colorq ph test. always reads lower than my Taylor kit. any ideas?

[krehbein]

Just keep in mind that these tester can get out of whack after a while and you need to re-calibrate. If I was in the business I would check them every couple weeks.

[nickgonzales]

i take care of about 45 pools a week and have been looking into trying out a digital test.
would you recommend the colorq or should i just stay with my taylor kit?

[cgoiugd]

Hello
I'm looking at adding pools to my line of services, I'm after a very simple quick device that I can take a sample of the water test it for
Salt levels and ph levels
So speed and ease of use
What would you recommend

[wowskaters]

hi Im building a swimming pool what system do you recomen sal water or regular

[whitemok]

is there a digital tester that test the four basic?
pH, chlorine, alkalinity, calcium

[gerardstuder]

Have you reviewed any floating pool chemical testers? Drop, Pool Sense, PHin, Poolsharkh2o, e Pool

[omCi]

is there a digital tester that will test for all the readings needed for the salt pool. Salt level, PH, Chlorine, Hardness etc, so that I don't have to deal with any other kits or strips?

[Adam-zwck]

Says gives an accurate pH reading with accuracy range of +/- 0.01-0.02. Shows 2 readings of 7.27 and 7.1 lmaoooo

[brucemoore]

These testers are not accurate I have tried and returned 3 of them use the strips
