1.0 out of 5 stars Cannot Calibrate, terrible directions
Reviewed in the United States on September 4, 2022

I will change this rating if somebody from the company can send me a link to something that better explains how to calibrate the EC on this.

I'm following the directions but can't get above 11.30 reading in the 12.88 solution. I've spent hours on this today trying to get it set up and trying to find online help. The only thing that's covered online is the PH calibration (I have the 6:1).

I really don't want to return this; I want it to work.

I'm beyond frustrated that I can't even figure out how to contact the seller to ask why this isn't working. There's no support website or email in the "directions" or on the box, or here on Amazon.

You're completely on your own when it doesn't work.

4.0 out of 5 stars Product works as advertised.

Product works as advertised. I'm using this for a medium sized home hydroponics system. The pH / temperature and TDS measurement precision is on par and even better than other hand held pH / TDS meters I have, but somewhat slow to converge. The probes are of reasonable quality, but I can see some rust in the TDS and temperature probes after two months of continued use. The device shows two temperature measurements, which is confusing. I wish all probes were removable and of the same quality.

2.0 out of 5 stars Inexpensive water monitoring solution
Reviewed in the United States on June 27, 2022
Verified Purchase
Bought this as a cheaper alternative to similar products offered by Blue Labs and honestly was a little skeptical because you usually do get what you pay for.

I have a bit of a unique situation. So, I built a DIY irrigation setup which collects pond reject water from a pond filter backflush valve. Rather than let that water go to waste, Its collected in a reservoir to be used for irrigation with the help of a pump and micro-irrigation.

I've always been curious about the water quality in this system since this is used for irrigation. I've looked at Blue Labs Guardian series water quality monitors but they're pricey and the "Connect stick" they offer isn't included and requires a dedicated PC to be running 24/7. I get the impression their products are more for professionals and commercial applications. Other inexpensive water quality monitors on Amazon only show the current reading and don't log data in "the cloud".

Anyways, I found this 6 in 1 monitor on Amazon that had Wi-Fi connectivity and logging of the data on a smartphone app. I hadn't seen this unit on Amazon prior to last week at the time of writing this review so I figured I'd give it a shot. This guy arrived yesterday, and I followed the instructions for setting it up. There are 3 packets of buffering powder and 2 vials of conductivity calibration solution Basically, you get 4 cups of water and fill them with 25ml of water and pour a packet into each cup (4th cup is just water for washing the probe off between calibrations) and follow the instructions. Easy to do. After that I set up the Wi-Fi with the smartphone app.

Each sensor has a suction cup for attaching the sensors to the side of a smooth surface under water. Just slide the sensor into the little ring on the suction cup and press it onto the surface where you want them. The main unit attaches to a tank or container using an included bracket though I accidentally dropped a small stone on the unit and while it survived, the two pegs on the back of the main unit that attach the hook clamp broke off :(

After all was set up and running, this device revealed how high the PH was in my reservoir! A quick Google search revealed the culprit. I run an aerator in my reservoir to provide oxygen to nitrifying bacteria that process organic waste from the pond filter. Apparently when water is aerated, carbon dioxide is offgassed which causes the PH to rise. (I'm NOT a chemist). It was at this point that I discovered another neat surprise that's not mentioned in the listing here, the Tuya app works with several smart plugs including the PowrUI ourdoor 4 outlet smart plug which I just happened to have my aerator plugged into. In the Tuya app I was able to explore the "Scene" section of the app and found that I can have it set to shut the aerator off when the PH rises above a certain level and resume operation when the PH comes back down (Much like IFTTT). I set this up last night and sure enough, when the PH rose above the parameter I had set in the Tuya app, the aerator shut off automatically. This morning I woke up and checked the app on my phone and sure enough, the PH dropped steadily throughout the night after the aerator had shut off. Once the PH fell back to ideal levels, the aerator came back on again automatically!

I did leave one star off though because the Wi-Fi signal is weak. I had to move this device around a bit to find a position that got me the best results. I initially wanted this on the side of the reservoir tank but got 0 bars in that location as well as a notification on the app that the device has gone offline and I moved it out a bit closer to where the router is, and while it does get better connectivity there, the signal is still weak. But it works in its new location although I still would prefer it on the side of the reservoir tank. Might need to buy a Wi-Fi extender and then try and move the main unit back to where I want it.

All in all, I'm very happy with this water quality monitor. I'd exceeded my expectations minus the one caveat.

UPDATE: I really should’ve waited to write a review because there are major problems with how this unit reports temperature! About a month ago I noticed my temperature climbing abnormally high. I contacted the seller regarding the issue and after numerous requests for detailed photos of the unit they sent me a new probe. Afterwords, I discovered that wasn’t completely necessary, because this unit doesn’t report the dedicated temperature probe readings over WiFi. Only displays those readings on the PH lcd. Instead, there’s a second temperature sensor inside the TDS sensor that this unit sends over WiFi. However, TDS sensors by measuring water conducting using an electrical current results in that sensor heating up and throwing the temperature readings way off! Right now the dedicated temperature probe is showing 81 degrees while the “main temperature sensor” is reporting 97 degrees! Seriously, why does this unit need two temperature sensors and why doesn’t this unit report the probe temperature instead of that of the TDS sensor? I’m sorry, but leave it to the China to design such a product! Shouldn’t be of any surprise though. Might end up looking at the BlueLabs Guardian kit after all!

I left 2 stars because the TDS and PH have managed to remain accurate. I would also like to thank the seller for at least attempting to fix the problem by sending a new probe. Unfortunately it does no good with how this device uses it.

Will not detect the 9.88 solution for the ph probe. So thats inaccurate. Calibrated to the ec/ppm solution they provided and it was off the next day. I'm giving it 2 stars because it came with everything.
