Definitely a step up from my previous set up
I have several fish tanks and ponds which I need to occasionally monitor water levels in order to help diagnose a problem when I see it. This sensor is clearly geared toward pools, and so this might not be the best use-case since the chemical makeup of a swimming pool is much more extreme. Still, here are my insights:I’ve been using a very inexpensive model which seemed to do reasonably well at TDS, and this model agrees roughly with what my old meter was saying. There is some variance, but if you have two meters you can never really be sure which one is closest to being correct.I have also been very interested in monitoring PH over time. I typically use test strips, and I will only use a proper liquid chemical PH test if I want a very accurate reading. This electronic tester appears to out-perform the test strip in terms of accuracy (after a recent calibration), but it feels like the resolution is better with the liquid chemical tests. I am unsure how often I need to re-calibrate the sensor, so I won’t fully know if I can trust this until several months later.As for the salinity accuracy, I don’t typically test for salinity, so I have no idea how accurate it is. Usually I just consider salinity as part of my TDS readings.

Muy mala lectura de FAC
Cuando llega lo calibro pero resulta que por llevarme de los valores que daba del cloro libre gasté una cantidad de cloro increÃble cuando chequeo con el medidor de cloro de piscina manual el de las gotitas yo estaba súper mega pasado de cloro mientras que este medidor lo que me decÃa que mi piscina tenÃa 0.6 de cloro si alguien que lea esta opinión me puede indicar cómo pudo calibrar el fac esa opción que mide el cloro libre en la piscina porque en el que me llegó no funcionó ni tampoco trae manera de calibrarlo

Iâm a Water Detective Now (And Itâs Way More Fun Than It Sounds)
I received this 7-in-1 Hydrogen Water Tester and let me tell youâthings got weird in the best way possible. On my recent trip, I turned into a full-blown Water Detective, pulling out my trusty device to inspect every bottled water, juice, and even that âmystery spring waterâ I came across.Hereâs the thing: not all bottled water is equal. Like, some bottles looked innocentâuntil I tested them and discovered they were basically just flavored tap water in disguise. Iâve started silently judging waters now. If it doesnât pass the vibe test on this gizmo, itâs exiling to the âmehâ pile (and trust me, that pile is huge).The screen stays backlit for a good five minutes, which is clutch for hunting down the reads in dimly lit hotel rooms or stealthy airport lounge sips. Plus, the anti-roll design? A literal lifesaverâI stopped chasing the dang thing mid-sip when it threatened to roll into my coffee. Seriously genius.Honestly, this meter turned every sip into a mini adventure. Iâve crowned only a select few water sources as âworthy of my trustâ (five stars). The rest? Treated like pesky criminals in a lineupâtested, judged, and given the side-eye.If you’ve ever felt suspicious about that fancy spring waterâor even just wondered if your juice is as pure as it claimsâthis tester turns you into the hydration connoisseur your feeder always wanted you to be.

Not efficient for swimming pool service
Hard to see the screen outside doesn’t tell the right information for swimming pool maintenance. Would not recommend for that purpose

An Absolute Game-Changer for Maintaining Our Pool!
My husband and I have been struggling to keep our saltwater pool in pristine condition ever since we moved into our new home last year. We were constantly testing the water manually and making adjustments, but it was such a hassle. That’s when I decided to invest in this digital pool tester, and boy, was it worth every penny!The thing that impressed me the most was how easy it is to use. All you have to do is dip the probe into the water, and within seconds, it displays accurate readings for pH, salinity, temperature, and a bunch of other important parameters. No more guesswork or relying on those finicky test strips!One feature that’s particularly handy is the built-in temperature sensor. It’s a lifesaver during those sweltering summer days when we need to make sure the pool water isn’t too hot or too cold for comfortable swimming.My only gripe, and it’s a minor one, is that the display can be a bit difficult to read in direct sunlight. But hey, that’s what pool umbrellas are for, right?Overall, this digital pool tester has been an absolute game-changer for us. It’s made maintaining our pool a breeze, and we no longer have to worry about chemical imbalances or any nasty surprises. If you’re a fellow pool owner, do yourself a favor and get one of these babies!Btw the packaging was really nice too.

My Waterâs Pretty Great â But Now I Have the Data to Prove It
Iâll admit it, Iâm a water snob. But Iâm not chasing hydrogen magic or miracle ion balancing. I just want to know whatâs in my water. This little 7-in-1 tester gives me a solid readout on TDS, pH, and now ORP â the three metrics I actually care about.Surprisingly, my tap water scores really well. TDS is low, pH is neutral, and ORP suggests itâs not trying to kill me. Thatâs more than I can say for half the hotel faucets Iâve met. This thingâs especially handy when Iâm on the road and suspicious of whatâs coming out of the sink; it wonât tell you definitively whether somethingâs safe, but itâll give you enough info to raise eyebrows or breathe easier.Accuracy seems decent. No, itâs not a replacement for lab-grade gear. I wouldnât use this to certify a municipal water system. But for personal use? It punches well above its price point. The readouts are fast, easy to interpret, and donât require a PhD in chemistry.I havenât bothered testing the hydrogen function (not a metric that’s important to me) but everything else works as advertised. The unit is light, pocketable, and way better than guessing.Bottom line: If youâre the kind of person who asks waiters if the ice is filtered, this little gadget might just be your new favorite travel companion.
