🌊 Ultimate 5-in-1 Water Quality Test Meter for pH, EC, CF, TDS, Temperature - Backlight, Wall-mountable, Rechargeable - Ideal for Aquariums, Hydroponics, Pools, Fish Tanks, Ponds, and Drinking Water Review

Price wise these are the best pH meters on the market. After the second calibration I thought that both my pH meters were broken and didn't read anything, but it turned out that my extension cord was switched off, so they died, wrote a bad review, bought a pH meter three times more expensive, got one Seller's response. that I'll probably have to plug them in and now they work great and I can travel 300+ meters!

I bought 2 of them. After each performance, I quickly realized that they couldn't be adjusted. On one Ph, on the other EU. I did a Revain exchange and got 2 different ones. Both worked immediately, but after 5 weeks both stopped. Once again, one side died on one side and the other side died on the other. I didn't think they would go to the manufacturer for a warranty, so now they're useless and on the shelf, and I'm $160 poorer.

Well that's crap, ec dongle wasn't read right out of the box. The EC fluid they gave me was 12.33 and 1413, well according to the instructions I set it to 12.33 and calibrated the key. Putting it in 14.13 reads 4.23 a bit, so I didn't make it that big, but it should work. Another issue is the PH button floating up and down after I calibrate it. Came in the next morning, I know I set ph @ 6.22 but I came in and read 6.70, hmm, can't quite trust that.

Everything was easy to set up and calibrate but when I tried to measure the pH it was below 2.3 which is clearly wrong. It was 6.3, tried to calibrate the pH side again and it never went above 4.5, so I understand the pH sensor is broken EC and TEMP were working fine :( UPDATE: I found out about my problem, the pH sensor was broken and I didn't notice it, I contacted support and they suggested charging the device fully which didn't work, then they said to try another sensor to check if the…

I had high hopes as I had previously bought 2 others of the same brand and had no problems with them other than having to adjust the EC/PH more often as I got older. This is to be expected, the batteries will die over time. This device was completely inaccurate out of the box which was not uncommon, the device did not set the pH above 6.22, I used a reference liquid of 7 and 6.86. I charged the device overnight and still couldn't set it up any further. Packed and returned. It's a shame, I…

Everything was easy to set up and calibrate but when I tried to measure my pH it fell into the 2.3 range which was clearly wrong. Got tested the same water with another meter and it was 6.3, tried recalibrating the pH side and it never went above 4.5 so I understand the pH sensor is faulty, broken and I didn't notice that I contacted the support and they offered to charge the device fully which didn't work .Then they said to try another sensor to check if the device is not bad, the problem is…

Yesterday I unpacked this meter for the first time. I'm about to build a new one and wanted to try out a new measuring device. I followed the instructions, the PH probe and the adjustment screw work fine. EC/PPM sensor and adjustment screw are not working. I turned it left and right several times and it doesn't change the EC calibration settings. I contacted the seller's support to claim the one-year manufacturer's warranty. They asked me to send them a video which doesn't work (which I did)…
