AquaChek TruTest Digital Test Strip Reader For Pool and Spa Water Testing - Tests for Free Chlorine, Free Bromine, pH, and Total Alkalinity - Quick & Accurate Results Includes 25 TruTest Strips (Blue)

I continued to compare my accucheck to pool store tester and the accuchek is massively inaccurate. I am switching to a new system. Because of the inaccurate readings my pool wound up with black algae.

As a new pool owner, I wanted to be sure the pool water is as safe as possible for my family. I started with Aquachek and hTh test strips which were simple and quick. However, I noticed some variability and found the colors were sometimes hard to be sure of, particularly pH or higher chlorine levels. Having a scientific background, I wanted a more quantitative testing method, that was quite simple to do. I was very disappointed with this item as at times it seemed to be a random number generator with no match to the test strip done at the same time. For about a week, I tested simultaneously with the Aquacheck test strip, hTh test strip and the TruTest Digital reader. For the most part the HtH and Aquachek strips matched, except the AquaChek strips seemed more sensitive for chlorine and seemed to indicate a higher chlorine level than the hTh srips. Unfortunately, with the Trutest I seemed to have variations at least 50% of the time and frequently got error messages. pH was routinely higher than strips and chlorine was also variable. It seemed more reliable indoors than outside in bright sun, but even indoors I would have to repeat the test frequently and was left wondering if I should believe the regular test strip, or the Trutest read out. Sadly, I don't think the average person who is looking for digital testing is going to be happy. Generally, I would expect that a person buying a colorimeter for digital testing is going to be looking for a more objective testing modality than strips. Sadly, if that is the case, you may find this device very frustrtating. I ultimately bought the Taylor titrating test kit and found this much more acceptable. Taylor Service Complete Pool Water Test Kit K-2006C While it is certainly more complex than the test strip or colorimeter, this test is very easy to do, does not take much time and seems significantly more accurate than the stips or the TruTest technique. I still use test strips for a quick check, but use the Taylor for my weekly testing, or when the test strips don't seem to make sense. I gave up entirely on the TruTest device. I think the person looking for a more objective and quantitative test will be thrilled with the Taylor test kit.

This product is amazing. Their direction need to be thrown away first thing. The correct way to use it is written by Deborah and it is super easy.. Thanks Deborah your amazing... As Deborah says: Here is what you need to know: The top button on the unit is the on/off button. This is labeled "1" in the picture but never described. The middle button ("2") is to review old readings. The bottom button ("3") begins the test sequence; this button is not described either (at least in the instructions that came with my unit.) By the way, mine displays "2.2" when I turn it on, so these findings may pertain only to that version. Steps: *Press the Start (#1, or top) button. The unit will turn on, display "2.2", and then display "On." *Have a test strip and your water sample ready. *Press the Test (#3, or bottom) button. The display will count down "3, 2, 1, Dip." *Quickly give the strip a brief dip into the water sample. No swirling. *Quickly give the strip a quick flip to remove excess water. *Holding the unit horizontally, quickly lay the strip into the test slot, without sliding it. It must be all the way up to the top of the slot. *Cover the slot with the black sun-shield provided. *At this point you wait for the test to proceed. You have to have reached this point fairly quickly because the test will start whether you are ready or not. *When the test is completed, the unit will show the three readings on the display.

The printed instructions leave a lot to be desired. The sheet that came with my unit seems to be missing the first couple steps (at least in the English version.) Step #1 says "After the 3, 2, 1 display countdown..." What? How do I get the countdown started? Looking at the manufacturer's web site I found an old version that explained it better. Here is what you need to know: The top button on the unit is the on/off button. This is labeled "1" in the picture but never described. The middle button ("2") is to review old readings. The bottom button ("3") begins the test sequence; this button is not described either (at least in the instructions that came with my unit.) By the way, mine displays "2.2" when I turn it on, so these findings may pertain only to that version. Steps: *Press the Start (#1, or top) button. The unit will turn on, display "2.2", and then display "On." *Have a test strip and your water sample ready. *Press the Test (#3, or bottom) button.

No swirling. *Quickly give the strip a quick flip to remove excess water. *Holding the unit horizontally, quickly lay the strip into the test slot, without sliding it.

You have to have reached this point fairly quickly because the test will start whether you are ready or not. *When the test is completed, the unit will show the three readings on the display. You can compare to your last few readings by pressing the middle button. Be sure to wipe the slot clean with a Q-tip or the cotton swab provided. I've been using this unit daily for several weeks now. I have done all my testing indoors and the results are reasonably repeatable and compare favorably to my color-match test kit. I'd give it 5 stars if the instructions were better and the repeatability was better. But as I said, I think it's good enough to do the job and I'm glad I bought it.

Debbo dire che non era per nulla chiaro il suo utilizzo. Non capivo a cosa servissero le striscie colorimetriche. Inoltre non ero al corrente di quanto fosse importante la conoscenza dell'alcalinità dell'H2O. Se non viene regolata a valori tra 80 e 120, risulta complicata la regolazione del pH. E in aree come le mie (Emilia) con presenze elvatissime di carbonati e bicarbonati è un processo molro, lungo, defatigante. E non sono molti i metodi analitici rapidi. Questo è veramente pratico e veloce.

Franchement très satisfait de l'appareil sa me rend bien service précis et clair

Aufgrund so einiger schlechter Bewertung hätte ich mir das Gerät wohl nicht gekauft. Aber mein bester Freund hat es mir empfohlen, also dachte ich mir kaufen, probieren und ggf. zurücksenden. Viele Leute schrieben, die Wiederholbarkeit der Testergebnisse wäre nicht gegeben. Das kann ich absolut nicht nachvollziehen. Ok, bei einem Chlor-Wert oberhalb von 5 sind durchaus Messwertsprünge von bis zu 1 möglich. Aber oberhalb von 5 sollte sich ohnehin kein Poolwasser befinden. Unter 3 sind die Ergebnisse bei mir auf 0,1 bis 0,2 wiederholbar. Die PH-Wert-Messung ist bei mir auch sehr zuverlässig und stabil. Die Gesamtkalität konnte ich nicht prüfen, da mit hierfür eine Vergleichsmöglichkeit fehlte. Die anderen Ergebnisse habe ich immer mit Tabletten und einer Farbskala überprüft. Ich habe die Version 2.2 vom Gerät erhalten (Stand groß drauf) und Messe immer mit der schwarzen Sonnenlichtabdeckung, auch wenn die Sonne mal nicht scheint. Also: Wer nicht mehr Tabletten auspacken, auflösen, schütteln und vergleichen möchte ist mit dem Gerät meiner Meinung nach bestens bedient. Ein Teststreifen enthält alle 3 Tests auf einmal. Eintauchen, auflegen und einige Sekunden warten. Voila, das Ergebnis!

Tells you on a digital display all you need to know to keep your pool clean and clear all summer long. You just need to remember to wipe the glass where the strip is placed after every use other wise readings can become inaccurate.

The product comes with 25 expired test strips.. therefore data were wrong when you test your swimming pool water...had to increase the PH while the PH level was good...you need to buy additional strips on the side
