TDS Meter Digital Water Quality Tester - PPM Meter with Temperature Test, 0-9990 ppm Range, Accurate TDS Tester for Drinking Water, RO System, Aquarium, Pool, Hydroponics

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: 9/29/2019 Installed 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: 10/4/2019 Returned 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.

Purchased this to further the quest to brew the perfect cup of coffee. The unit is pretty nice and reasonably accurate, especially for the super cheap price. The only downside is that there is no auto shutoff. Forgetting to manually shut it off seems to result in dead batteries in a day or two.

Love it! Use it every month

I have a few of these meters and got another to have on hand. this one is way off the money and I did not realize it until after the return window closed. The meter works at roughly a 10% higher reading. 200TDS water reads 227 when three other meters are within a point of each other 2 points between two of them and they all have an adjustment screw That i did not know about until I saw a youtube on it.SO all of my over 10 dollar ones have an adj screw and work and this one does not and is way off the mark. I need to dial in TDS for shrimp tanks so this is garbage for that. You might be able to find a use for it but my fear is picking it up by accident so in the garbage with it...

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.

Take the batteries out or else they probably will go flat like did mine. This was used once when I ordered it and came to use it again just now and it’s no longer powering on. Had I noticed this used lr44 watch batteries from the getgo I would have looked into other options. But I still can’t knock it for under $10 bucks this is still a bargain even if it’s to use one time and throw away. It’s almost more cost effective to do that since the cost of the batteries can sometimes be greater than or equal to the cost of the device! I’d like to see the next generation of these running on a single cell Li-ion battery which would surely help with wasted batteries

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.

I’ve tried it in different water qualities and the consistency is spot on. Good product would recommend

This item gave the wrong measurements, I compared it with a meter from the filter company and it was giving me much higher measurements. I returned it.

Buen producto. Sirve lo básico para el hogar.

Excelente producto me funciona excelente buena calidad

No gasten en este producto lo compre para una purificadora solo sirvió una vez y nunca más prendió lastima y tan caro que me costó
