A TDS meter (aka ppm pen, nutrient tester, tds stick) is an inexpensive and convenient digital tool to instantly check your overall water quality. TDS = Total Dissolved Solids, which is any salt, metal or mineral in the water. With the push of a button, the TDS meter can tell you your overall water purity level, which will be displayed on the screen in ppm (parts per million). The lower the TDS level, the purer the water, with 0 ppm being pure H2O. The TDS meter is great for checking your tap water quality, or knowing when to change a filter. (The meter DOES NOT test for biological contaminants or PH level.) The TDS meter is a great tool for drinking water, water filtration and purification, hydroponics (test your nutrients), aquariums, RO/DI systems, pools and spas, and more.Specifications: * Measuring Range: TDS: 0 - 9990 ppm (parts per million) Conductivity: 0 - 9990 µs/cm Degrees Celsius: 0.1 - 50.0°C Fahrenheit: 32.0 - 122.0°F * Accuracy: ± 2% F.S * Net Weight:2.82oz(80g) * Size: 6.38 x 1.18 x 0.63 inches (16.2 x 3.0 x 1.6 cm)Package Contents:1x TDS Meter 1x Instruction sheet 1x Portable carrying case 2x CR2032 Batteries

Cheap, not water resistant at all. Came with calibration issues.
Not a fan. I picked this up as a back up, for those "just incase" situations. Tested it, compared to a properly calibrated BlueLab digital ppm meter this thing is not worth the cash. Out of the box it came with calibration issues that i'm not sure how to fix, it reads between +\- 0-200 ppm off of my bluelab. And the issue changes through resets for example, Ill reset the probe after testing a solution at 800 ppm Ill retest the SAME solution and get a different result each time.... HOW?It has other problems like water seeping into the housing if the liquid is deeper than an inch, causing all manner of issues. The covers do not seal well for storage, etc...I don't know if it broke during shipping or if it is just terrible for everyone, but i'm not happy. Since its only $10 i just tossed it, no big loss to me but I hope it will save someone else out there some cash, quality matters with measurement devices.The black storage case and extra battery were nice, so kudos there i guess.

Works as advertised!
Great product, and the readings are instant. I first tried they product with bottled water, then immediately with tap water. The water bottle was green and the tap water was red, indicating water you should not drink.
