Its compact, rugged metal design fits comfortably in your pocket, making it ideal for professionals and home users monitoring water purity across diverse applications—from drinking water and filtration systems to hydroponics and aquariums.

## Description

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 stands for Total Dissolved Solids, which is any salt, metal or mineral in the water. With the push of a button, the TDS meter tells 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 and knowing when to change a filter. The TDS meter is a great tool for drinking water, water filtration and purification, colloidal silver, hydroponics (test your nutrients), aquariums, RO/DI systems, pools and spas, commercial and industrial applications and more. The TDS meter is a rugged model that includes a protective carrying case. Pressing on the temperature button allows you to test the temperature of the water (allow 1-2 minutes for an accurate reading for the temperature compensation). This is the world's most popular handheld TDS meter for both industry professionals and household use.

## Questions & Answers

**Q: Pardon my ignorance but after you get the reading what do you compare the number to? I didn't receive any chart.**
A: You do not compare it to anything the number is the amount of electro conductivity in your water(ppm of dissolved solvent witch are mostly minerals)Pure water that reeds 0 ppm does not conduct electricity. If you want clean drinking water try to filter it to were it is around 50 ppm that way you still get some minerals witch your body needs. If you are using it for mixing fertilizer for your plants you should not exceed 600 ppm when they are small and do not exceed 1500 ppm when plant are larger with more roots.

**Q: The instructions say it's warranty is for 3 years. It's odd that there is no company name as to who it would be returned to. Who is the manufacturer?**
A: Hi LmariThe brand name iSpring is stamped on the TDS meter itself. We are currently updating the manual for the TDS meter due to the typo in the warranty. This meter has a 1 year warranty and not 3. If you are experiencing any problems with this product please contact us at (678)261-7611.ThanksiSpring

**Q: Do it need a calibration solution?**
A: Sure it works right out of the box, but i it accurate? The only way to know is with a calibration solution. Most meters are quite close when they are new, but as time goes by, the accuracy can decline. If you want accurate readings, get some calibration solution.

**Q: Essential minerals are also picked up by TDS meters and that is not an effective to way to check or test water quality. True?**
A: True. TDC=S meters usually measure the EC of particles to indicate TDS (Total Dissolved Solids) Dissolved solids can be good or bad.

*by J***W on 23 January 2022*

Our well water tests anywhere from 700-800 TDS. This can vary from samples taken a minute after another. I am not sure how normal this is for samples to fluctuate on the same line this way but in comparison to testing the filtered water samples from my RO faucet I have to say it seems the tester seems pretty accurate. My filtered water samples read steadily from 21-22 TDS. Store bought cooler water reads at 11 TDS from spigot. I'm giving this item a 5 star review because I have no reason to believe it isn't operating as designed to despite large fluctuations in close water samples from tap. I think as well water sits in lines there is more TDS, the longer I run lines before I take the sample the lower the TDS number readings are. This is consistent.
