TDS Meter Digital Water Tester, KINCREA 3-in-1 TDS, EC & Temperature Meter with Case, 0-9999 ppm, Professional Water Quality Tester for Drinking Water, Aquarium and More JR021

I needed a dissecting kit for my A and P class. I don't know about other schools, but my bookstore charges an arm and a leg for just a scalpel and tweezers. So I always come to Amazon as my first stop. After researching price and quality vs instruments I may need. I chose this one and boy I'm sure glad I did. It came and I was pleasantly surprised. The quality is definitely there with the price of this kit. It cleans and sterilizes great. The case is a nice added feature to keep the tools all nice and neat. Fellow classmates are looking to purchase this kit to replace the kits they had previously purchased from the school. It's working out great for me and my children are also taking A and P next semester so I'll be able to pass it along to them. Thank you for such a great product and price.

Works great and I got my dad to buy one a few days later. It’s great for testing your water pitcher filter when new and again when the light comes on. Also is great for checking water in general. This is my 2nd one.

This kit is for the emergency first aid kit in my off-road Jeep (a .30 cal ammo can with both basic and some advanced supplies) ; I know it's not FDA rated for use on humans, but in a pinch, miles from help, it will do just fine and has enough tools do do a variety of jobs and then stitch the work up if need be (when used along side other items, by someone who is properly trained in field-expedient emergency wound treatment, don't try this at home, kids)..... The kit is nicely organized and packaged, the tools are of decent quality and can be sterilized , and for the price you get a good variety of tools in a nice zippered case that keeps it all together . it shipped quickly and the seller even followed up to make sure the items arrived on time and were satisfactory.

I'm on well water and although my water tests passed EPA guidelines, I was concerned about the TDS in my water. Shipping was quick and I was able to test my water minutes after opening the package. My initial tests were 275 ppm. One of the reasons I purchased this model was for the temperature adjustment feature. My hot water did test higher than my cold water, so it looks like the ATC feature works. Based on my testing, I purchased a Hydro Logic Stealth 150 with the upgraded Carbon filter. My readouts were 242 > 150 > 27 > 6ppm...Tap water > Brita filter > Kirkland brand bottle water > RO filtered water. Happy with the purchase.

I found this one on Amazon for a reasonable price. You can't go wrong with this one. I use it mostly to check my C-PAP humidifier tank each night. Distilled water should always be (0.00ppm). My city water is around (115ppm), far too high to use in a C-PAP machine. This tester comes in a small leather looking case, and the battery is very easy to access. I also have traveled with it to test the purity of water where I go, it's amazing what you can discover. It's a Great device at a Great price.

Besides the fact that most of the reviews here are for a massager, this is a good water tester. Not sure if it is accurate but my filtered water and my tab water show the same ppm. Could be a filter issue.

Cool color, works well, does what I need it to. I use this for my carnivorous plants and tropicals. Good idea to keep an eye on the state of the water quality.

Hi,I'm a plumber.I always check my client's TDS (Total Dissolved Solids) as it has been increasing like crazy around our area.I have two other meters. In this case, one says 257, the second one says 254 this one says 152.Errors like these can make me mislead my client telling them everything is ok while are actually having hard water.I always check the water with two different meters, and they are all close in results, except this one that is way off.As a piece of advice, always have two different brand meters and compare, never trust the results of just one.
