Smart Pool Monitor, pH and Chlorine Tester for Swimming Pool, Salt Water Pool 7 in 1 pH Chlorine Salinity ORP EC TDS Temp Monitor for Inground Pool, Above Ground Pool, Spa, Hot tub

No measurement is really correct, I did everything indicated in the manual, what's more, look for videos about this product on YouTube and information on Google, which is very little. The product looks promising, BEWARE I BUY IT TO MEASURE THE CHLORINE LEVEL, I first tried the first one that came to me, it never gave me the chlorine level, it always gives you 0.1 MG/l which is 0.1 PPM, I did the test again reset and redid the measurement adjustment with the 4 bottles that come with the product, it kept giving wrong information. The PH is not correct either, if you have a PH of 7.4 it tells you 7.8 or when you open the application it shows you 6.8 and it goes up little by little until it reaches 7.8. As it can show you 7.2 in the PH and then it goes down to 6.8 or 6.9 in a few words, very little precision in its measurements.Now the ORP, I have an ORP of almost constant 700, and he just shows 493.SALT: This shows 1650 PPM of Salt which is also incorrect.Call amazon support as we well know amazon support is very inaccurate so they told me they would send a new item as a replacement but still i wrote to the supplier i wrote to them and they told me the equipment is completely accurate that it does not fail, and what the team is telling me is that my pool needs CHLORINE, my pool maintains CHLORINE levels of 3-4 PPM at all times because it is a pool that is not used and is maintained in that range due to maintenance weekly that is given, even so it caused me doubt, I went and measured the chlorine and it had 5 PPM at the time of the claim to the seller so according to the seller it should show the CHLORINE like this "" ---- "" I never saw it work well, anyway this product does not measure anything correctly.The positive, if it maintains its communication with the cell phone, its solar cell, if it charges the battery adequately, I think because both arrived with 50% batteries and I take them to 87% in less than a day, so if I consider that It is correct, but for the rest, I DO NOT RECOMMEND THIS EQUIPMENT TO ANYONE.

I gave it a 5 bc it was a good product but i had to send it back. It wouldnt link up with my 5ghz wifi...it needed to be on 2.4ghz. Oh well, seemed lime a good product.

The monitor is good. It does a good job for most of the things it monitors but not chlorine which it shows as -- (none) but test straps show it as the correct level 2-3ppm...For a quick daily check from anywhere it is a great deviceThings I would like to see improved:Chlorine sensor working.Leader included as if not tethered it will be stuck in skimmer and not be charging.From other reviews ti's item is a vit hit or miss with different people having different issues or none. I wish I had enough but not the case.

I bought three different ones, all looking identical, but interestingly, they were all different manufacturers??? And distributors?Each one of the three had something that wasn’t working, one wouldn’t sense, pH, one wouldn’t sense salts, one wouldn’t sense chlorine, you can calibrate them all day long, they would not take calibrations and could never get it to work. The sellers all harped that I must’ve forgot to take off the sensor covers, I find it hard to believe they think everyone is that dumb.It was very handy to check the temperature, and I really really like that feature but that was usually the only thing that worked. They are complete garbage. It is a shame because I would pay $500 for something that did all these things accurately and be able to connect to the Internet. It’s a shame.

Does not connect directly to an app. Will need more equipment to make this work. Beware

Con el kit de calibración que trajo no logre calibrar bien el PH ya que nunca bajo de 6 y 9 cuando la muestra del kit dice 4 y 7

Product support will keep leading you on until your past a certain return window. Then you will not get a full refund! Returning unit for same reason that most people do….chlorine readings not in range!Do not buy! Another note is that I purchased at $75.99 and now all similar units including theirs are all well over $200!

Terms and conditions are Chinese Communist Party controlled, and agreeing to the t&c means they can send data from the app on my cell phone to them!!No way i would have bought this had i known about this, good thing i read the t&c stuff.Just threw this device in the trash.
