Smart pH ORP Controller Aquarium pH Monitor Wi-Fi for pH/ORP/Temp Measurements in Water w/Calibration, 3 in 1 Nutrient System Dual-Plug Fit with CO2 Bottle & O3 Generator for Hydroponics Plants

The media could not be loaded. I am happy so far with this purchase because I don't have to do testing EVERYDAY. The calibration was simple to do and my numbers seem to hold, other than flow fluctuation. (I still do regular testing once a wk to make sure). I wish I would've found this baby months ago smh.

pH probe lasted 5 months before it stopped working and I had to buy another one. Conductivity probe has now gone out and will not calibrate. Cant replace it since its hardwired in. Dont recommend for saltwater tanks. Temp probe coating corrodes away fast and has copper as the base metal.

I just replaced my last aquarium dash board with this Smart Water Quality Tester meter. It's accurate. Follow the instructions and you are up and calibrated and running. The app works without problems. I can see my aquarium numbers on my phone. It's light and sticks on the wall with the alien tape from my previous dashboard. I think it's grand. Oh and one more thing, calibration on my janky old dashboard was accomplished by turning a very small screw with an even smaller screw driver. Like an animal. This dashboard has a button for calibrating and that makes it wonderful.

Once I got it calibrated I love that it sends the data to my phoneVital information at my fingertips at all times

For the price it's ok. I've had it a few months now. Used on a FOWLR marine aquarium, I was never able to get the app connected. Salinity reading is consistent and backed up by refractometer testing. The Temp/pH reads correctly when working but frequently switches itself from Fahrenheit to Celsius and when it switches to Celsius the readout gives nonsense: "pH 00.00 Temp 194°C " for example is what it currently reads at the moment of typing.

Will not hook up or link to wifi. Tried it several times , at home . Then two other individuals homes.. Got it for that entire reason.Maybe a bad. Unit. Don't know . But not wasting anymore time on the issue. You get what you pay for..

All I needed was a low cost meter, I have high quality probes and didn't need the control function plug-in portion.So I cut that off, added a 110 plug to the meter, and I have a great bench meter for my lab at a fraction of the cost of lab grade meters. So can't comment on probe function or pump control function.I was very pleased with the ability to calibrate using either the included reference standards, or the more common industry 4.01, 7, 10 solutions.

It came today a month earlier than the original estimated delivery date inside a hard plastic carrying case with a few accessories and instruction booklets I do have to say it's about 4x smaller then I expected, this thing is smaller then a Gameboy pocket. installation was incredibly simple and quick it probably took me longer to put the hanging nail in the wall then to get all the probes plugged in and placed where I need them. (I'm using this for an aquarium) I haven't turned it on yet because I'm still setting up everything else around it but it appears that it won't be much problem at all to calibrate
