Seems to work great. Easy to understand instructions. Solid product. To get a 5 it needs to whistle or something.

Works as it should
Perfect!
Customer Review –
Great way to check the basic quality (hardness) of your water
Wanted a way to tell what the quality of my water is and if it varies over time. This device seems to do the job. It’s very easy to use. I found that my water is just ok, not quite hard but getting close. I don’t have a way to tell if it’s really accurate, but it does seem to match other indications of the state of my water. The price point though makes it worthwhile.

This Meter Left No Doubt
This TDS meter appears to provide reliable measurements. I ordered it to compare test results with another brand of meter I’d recently purchased, but was unsure of. When testing water right out of the tap with this other meter, the reading first appeared as 43, then immediately went down to 38. Then it went up to 39, and flickered back and forth between 38 & 39 until finally holding steady at 38. Then I tested water that was filtered through my ZeroWater system, using a new filter. I’ve been using this system for ten years, so I know that a new filter will remove all Total Dissolved Solids, with test results of 000. The other brand gave me a reading of 001. I retested a few times, and the result was always 001.Next, using the same glass of tap water as the source, I tested it with the NATFORTREE meter. The reading was instantly 35, and remained steady at 35. No fluctuation! I then tested the same source of ZeroWater filtered water with the NATFORTREE, and got a reading of 000.Based on my experiment, it appears to me that the other brand’s numbers are a little high. It could be that it’s a WAY more sensitive instrument, and that’s why it measured the filtered water at 001. But it couldn’t seem to “make up its mind” before settling on a measurement of the TDS in the tap water. I like how the NATFORTREE made a “decision” immediately, and never wavered. It left no doubt that the reading was correct. So I believe the NATFORTREE provides the most reliable reading, and it will be my go-to from now on.

Ugh
These meters are very delicate. Second one that didnât work, even with new batteries. Too lazy to return itâ¦.

Helping me monitor lake water quality.
I am adding this TDS meter from NATFORTREE to my procedure during lake weed treatment next year. While TDS is not expected to be an issue, it appears to be easy to do and it will help assure the community I am monitoring everything. I like the simplicity of this meter. If I detect an anomaly, I am sure I’ll be stepping up to a higher precision meter. I’m pumping samples up from 3 different depths and then running a battery of tests of each sample before and after treatment.

Working well. Tested in differnet types of water.At the moment I don’t have any issues
Teacher –
Not sure it is accurate
Mr R Hall –
Not sure about the accuracy, it can change by +/- 10 in the same cup of water (taking it out and putting it back in again multiple times). Also first use and the batteries are either 98% flat, or the display isnât working correctly as itâs dull and hard to read.
