TDS = Total Dissolved Solids, which is any salt, metal or mineral in the water. With the push of a button, the TDS-3 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-3 is great for checking your tap water quality, or knowing when to change a filter. (The meter does not test for biological contaminants. ) The TDS-3 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-3 is a rugged model that includes a protective carrying case. This the world's most popular handheld TDS meter for both industry professionals and household use.

Review: Appears accurate and really handy to have! - So this little baby let us know that the new home we bought has a refrigerator with the water dispenser/ice cube maker hooked up to a water source that comes from the softener! Seriously. What contractor does that? The prior occupant was an older lady who probably has sky high blood pressure drinking softened/salted cold water and ice cubes from the frig. That is so sad. The frig filter cannot filter out all the salt. It tested around 750 ppm. 200 less than outdoor faucet water. If it had non siftened water and a new frig water filter it should have tested under 100. Unfiltered tap water from the kitchen sink that isn't hooked up to a softened water source tested at 750 ppm. Water from the sink side reverse osmosis tested at 50 ppm. Distilled water (just for fun to see if the unit is anywhere close to accurate) was zero. Yay! The case is handy and it will ensure the cap for the unit won't get lost. The digital readout could be a bit clearer to read, but no real complaint enough to take away a star. The unit clearly warns that it is not water proof and to only submerge it up to 2 inches. We use the cap to hold the water for testing and then that ensures the unit won't get damaged. Review: Very High Quality Test Meter - I have used this test meter for many years and it is still working well. It is well made and when comparing it to other ppm meters it seems very accurate.

There costumer service is the best I have ever seen! Sean has helped me trouble shoot and also offered quick and easy assistance with parts and filters even when my system was no longer in warranty.

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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Appears accurate and really handy to have! *by J***N on April 22, 2015* So this little baby let us know that the new home we bought has a refrigerator with the water dispenser/ice cube maker hooked up to a water source that comes from the softener!
