TDS Water Quality Tester Digital PPM Meter - Quick Accurate Testing for Drinking Water Pool Aquarium

Just got it today and started using it.Used a store bought distilled water and it was reading 002 ppm, which should be about correct since distilled water essentially is suppose to remove all impurities. Used it on our filtered faucet after water softener + filter and reading 377, and faucet without filter reading 406. Outside spigot (hard water) 460. These are PPM = mg/L. Dissolved 1 tsp of salt in 1 cup of water and reading 650 ppm but had a x10 symbol which means 6500 ppm. Using the distilled water as reference it seems to be pretty accurate. Will be installing a reverse osmosis filter instead. Will see what type of numbers this device will show.Very easy to use. Didn't really need to read the manual. Just remember the entire device is not water proof so don't try to dip the entire device into the water to measure.Update: 9/29/2019Installed the Brondell Reverse Osmosis filter today and got readings of 015, 025 while the regular sink without the filter was reading 356. This is softened water. Therefore, something must be working right. I've also notices some bottled or "natural spring" waters are reading in the 100 range which I assume contains some minerals, etc.So both the TDS meter and my RO filter is working. The RO filter is another story cause its leaking water.Remember: the TDS is total dissolved solids. It does not tell you what those solids are. I assume because of my water softening, its exchanging Ca+, Mg+ with Na+.Update: 10/4/2019Returned the Brondell, went to HD and bought the GE RO and didn't work, at least it didnt leak like the Brondell. Finally, Menards model worked. It was also the least expensive of the three. Easy install and worked like a charm. See photos of readings. Obviously the first is straight from the faucet with water softener while the second is through the RO filter.

I went to use this after having it for 2 months and it wouldn't turn on. Either the unit is bad or the batteries are dead, but the description says they should last up to 3 yrs. 2 months is a far cry from 3 yrs. After reading several other 1 star reviews I see that this is a common problem with this one. I will be buying a different one to replace it.

Easy to use and accuracy is okay.

I didn’t attempt to use this device until recently. I was saving as a backup. When I tried to use it temperature control worked fine but TDS read only zero. I’m very disappointed and would like a replacement but obviously it’s a little late. I’d love to have this passed on to seller.

I can’t comment as to the accuracy of this tool because I have no way to check it’s accuracy. What I can say, is that it is easy to use and seems to work well. When I first bought it I checked the water coming out of my RO system. It came up with 3ppm, 3 months ago I tested the water again and it them tested 8ppm. It has now been 1 year and time to replace the filters and the water is tested 12 ppm. So I guess it’s working like it should.

Pretty decent. Nice that you get a pleather case for the TDS meter. Comes with batteries installed. Nice and simple easy to read. I gave it 4 stars because the temperature is a little off like by 10 degrees. This was verified with 3 separate thermometers but if you are looking for a TDS meter because you need a thermometer then idk what to tell you. Overall I would recommend this product to anyone. This is one of the rare items that are really cheap in price but is excellent.

As received, the product did not work. The batteries were dead. After buying new batteries, which added more than 50% to the cost of the product, the unit worked as advertised.

Arrived w/ dead batteries ... no big deal, I have a bunch in my fridge. Neat that it's a thermometer too. No idea if it's precise, but it shows expected differences between city tap water, a friend's well water and distilled water ... so I trust it. I recommend!
