TDS Meter, Water Quality Tester Filter Pen, Accuracy Testing Water Quality for Drinking Water Purity Test, Swimming Pools, Aquariums, Etc.

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.

Quick cheap way to measure water quality through measuring TDS. The instructions to use the device are clear and it comes with couple of spare batteries and ability to store measurements in device memory.

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...

All that's needed is 1" of water in a clean cup to test TDS. Works as expected.

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.

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.

Very easy to use and the price was good. I use it all the time especially to keep an eye on the quality of the distilled water I use on carnivorous plants! 🌿

Buen producto. Sirve lo básico para el hogar.

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

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
