It works really good I tested a lot of water some that I knew was full of junk and others that was highly purified and it tested correctly each time Im sure there is room for error but this device worked a lot better than the one I had before

It works right out of the box, super simple to use, and really fast. I filled a small cup with water, removed the protective cap, powered it on, and dipped it in. The readout is instant. I took it out and dipped it back in a few times, and the readings were consistent, within a few points. This gives you an accurate reading of the PPM in your water.At home, it showed a 27, which is great! I took it to a vacation home and tested the water there. I inserted the tester, and it showed 180, with the display turning red. Yikes! The red indicates it's measuring an excessive amount of particles. That might not necessarily be bad, but it's definitely not desirable. We have a water filter jug in our fridge for drinking; we just put tap water in it. I tested the water from the filter jug, and it was 108, and still read red. So, while the filter definitely helps, it sure doesn't remove *all* the particulates!It's a great tool and really eye-opening. Simple to use and lightning fast. Very cool.

Very easy to use this water quality tester.I have no way to verify its calibration, but I find myself testing the various water sources I have access to and the range of readings it gives are both (1) consistent when using the same source for samples and (2) more or less in line with what my intuition would be.I intend to install an in-line filter for drinking water in my kitchen sink and am excited to be able to use this to put some numbers to the efficacy of that.

Great TDS meter.It seems to be accurate.I love the lit display. It is very clear and easy to read.It's green up to 40 ppm and then its red after that although I don't know why they picked 40. My water in my house runs 200 - 250 ppm and it's fine.I got it for my reef tank. It's very picky about its water.This meter can't be calibrated but I have no interest in dealing with that mess any way. My old meter was like this one and I used it for over 10 years till it quit because the on/off button broke. It worked great till the end.I tried the thermometer. It seems accurate but it's really really slow and not really needed. My tank has a thermometer.As far as TDS meters go this is a good one.Great item

It's not bad

I ordered this unit because I've been concerned about the accuracy of the cheap TDS tester I've been using. When I tested my filtered water (ZeroWater filter) I thought the new tester was broken - it registered 65 ppm. But when I used my old cheap tester it read 67 ppm - past time to replace the filter! I don't have an independent standard other than grocery store distilled water - that measures 1 ppm on this tester and 0 ppm on the old cheap one. That's a confirmation of sorts, I guess.The conductivity test is less useful, to me at least. I don't have any kind of intuitive feel for what it means for water purity. I think it's an indicator of the density of charged ions. I suspect that the unit measures conductivity and calculates ppm from that - so conductivity is its "native" language.The temperature measurement is present because the unit does temperature compensation for the conductivity and TDS display. I couldn't tell where the temperature measurement was being taken. If it's measured at the electrodes it seems quite inaccurate. I was testing filtered water at room temperature (around 68 F) but it was reading 85 F. When I checked "tap" water, which is much colder, it was reading around 70 F. Not a problem for me, as I don't expect to ever use this device as a thermometer.The materials, fit and finish are very good, and the battery compartment is easy to open for battery replacement. The display is clear, bright, and readable. It's a 4-digit display - the advertised range is 0-9999 ppm - far beyond anything I might want to test. Anything over 1000 ppm is undrinkable. There is a "hold" button so you can pull it out of the tested solution to read it.There was no indication on the box or in the enclosed literature of the country of manufacture. I assume it was China or some other Asian country, as the instruction sheet was clearly written by someone who spoke English as a second language and the syntax was similar to what I've seen from China. The text on the box was much better. In any case the instructions were clear and useful despite the sometimes innovative syntax. It uses a CR2032 battery (not mentioned in the instruction sheet or on the box, but it does have prominent warnings that there is a battery that could be dangerous if ingested).The bottom line is that this is a good quality, easy to use instrument that appears to be accurate where it matters. It's only slightly more expensive than my cheap tester, and worth quite a bit more. I like it, and I recommend it.

Very straight forward device. A TDS device simply measures conductivity in water to detect how much solids are in the water.It may be surprising to hear, but absolutely pure 100% water consisting of H2O is actually not conductive at all, it's the salts and minerals found in almost all natural and processed water that act as conductors.The device simply has two metal probes that it electrifies, and tests the conductivity between the probes to determine the water's purity.Operation is very simple, press the "On/Off" button and it lights up and is ready for testing.The backlight is very bright and kind of makes it difficult to get clear photos, but the numbers are very easy to see in person.Readings are near instant with numbers coming out within 1 second of any change.Tested some pure distilled water, it read 0001 which is expected.Tested some purified and mineralized bottled water, it read 0016 which is also excellent.Tested my tap water, it read 0031 which I'm very happy to see seeing as I drink maybe a gallon of it every day in the summer.The included chart on the box says readings of 0-50 is excellent, with 51-100 still being very pure. Though the meter backlight will turn red when readings go beyond 40 which is a little weird.And lastly just to see how sensitive the meter is, I poured some salt in the cup and stirred it around, spiking the scanner to over 9000.
