Fivota pH and TDS Meter Combo, 0.01 pH Accuracy pH Meter with ATC 0-14 pH Test Range, Temperature and TDS Test Meter Range of 0-9990ppm, 3 Meters Combo Ideal for Various Water Test Requirements

Testers to check your home's drinking water is safe to drink. There are 3 digital testers included, one is a pH meter and the other two are TDS meters. The TDS meters test the total dissolved solids levels in water and the pH meter tells u how acidic or alkaline the water is. The tap water in my area sometimes has a smell and taste like chlorine and I was concerned if it was safe to drink at that time. It also leaves a lot of scale in my kettle so wanted to check it because of that reason too. The meters are easy to use by following the simple instructions and will give u the precise level of pH & TDS by showing it in the digital displays after testing. They come already fitted with a battery in each testing device and they are small enough to take with u when u travel to other places to check the safety of drinking water. They are also suitable for scientific testing in laboratories so u can rely on the accuracy of the results.

Seems to be accurate enough. I tested the TDS tester against a lab quality tester we use at work and it gave identical readings on several water samples. I use it at home to test the purity of the filtered water I use to make a salt water mix for my marine aquarium and it gives me real peace of mind that I'm not polluting my tank. Very easy to use and a great price for 3 digital testers.

I have purchased this to be able to accurately test the PH levels of my hot tub. I've always been good at maintain the chlorine levels, but I've always struggled with the PH levels. Prior to using this I measured my PH levels with coloured test strips, which I always felt were difficult to read accurately, making it difficult to maintain a good PH level. Since I've been using this, I can now see a digital reading of my PH level, so it's much easier to know how much PH Plus or Minus to add to the hot tub when required.

The kit came with 2 TDS meters and both read different values out of the same cup.Tried with tap, filtered and bottled water and reads 50-100ppm difference between the 2 devices.Now I need to compare both of them with a known sample to see which is more acurate.I guess at this point will use the average value of both readings 😂It is ok to use as a guide by measuring bottled/distiled water and using that for reference.

PH pen broke after a dayBut apart from that the others work fine very well packaged comes in a box with pH testing solution very good value for money however the pH pen doesn’t work plus tds pens say two different readings with the exact same water

The PH tester failed in a single day. The TDS + Temp meter is nowhere near accurate. The TDS meter is still working, so that's something, but I would suggest just buying a proper TDS meter on its own and avoiding this cheap rubbish.

The media could not be loaded.  Does the job as expected. Nothing additional is needed so everything is within the price including buffer powder.Can't complain for the price and accurate as it gives the same readings as my other ones.

What a great testing kit . I'm always testing my water as it ain't that good . ..I was very pleased as they all.came with batteries fitted..so ready to straight of of the box
