High TDS level alters the taste of water and makes it salty, bitter, or metallic. High TDS levels also indicate the presence of toxic minerals which is hazardous for health. High TDS makes water hard, leading to scale build-up in pipes, dry hair, spots on utensils and also makes the kitchen appliances ineffective. Checking the TDS level of water helps you avoid these problems beforehand. The TDS level in water can be determined with the help of a TDS meter. Results are displayed in parts per million (ppm) — a reading of 1 ppm means that the water contains 1 milligram of dissolved solids per kilogram of water. According to the EPA, the maximum concentration of TDS for drinking water is 500 ppm. Specifications Range: 0~9990 ppm Temperatures：32~212℉ Accuracy: ±2% full scale Power Source: 2 x 1.5V (button cell) Weight: 1.76 oz. Dimensions: 6.2 x 1.2 x 0.8 in.

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: Like iSpring's quality and pricing. - I bought this Hardness Test Meter when I purchased my iSpring RCC7 system. It works great and is a must have for an RO system. This unit is still working fine for the last 8 years, I'll probably have to replace the battery one of these days. I really appreciate iSpring's quality and pricing. ## Features - Used to test the ppm level of hard water - Automatic shut-off function helps save energy - Hold button retains measurement value for convenient reading - Comprehensive: great tool for testing hard water contaminated with arsenic, lead, aluminum and other metals - Hold button: holds measurement value when meter is removed from water for convenient reading and recording ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00IDBZ1A2 | | Additional Features | High Accuracy | | Age Range Description | Adult | | Best Sellers Rank | #45,125 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #43 in Lab pH Meters | | Brand Name | iSpring | | Color | Grey | | Customer Reviews | 4.0 4.0 out of 5 stars (886) | | Display Type | Digital | | Global Trade Identification Number | 00662425070015 | | Included Components | 1 TDS meter | | Indoor Outdoor Usage | Indoor, Outdoor | | Item Length | 7 Inches | | Item Type Name | High Accuracy TDS Meter with Temperature Function | | Item Weight | 0.11 Pounds | | Manufacturer | iSpring | | Model | TDS3-FBAK | | Model Name | TDS 3-Button Digital Water Quality Tester | | Outer Material | Plastic | | Part Number | TDS | | Power Source | Battery Powered | | Product Care Instructions | Hand Wash Only | | Response Time | 2 minutes | | Reusability | Reusable | | Style Name | Contemporary | | UPC | 662425070015 | | Unit Count | 1.0 Count | | Warranty Description | 30-Day Money Back Guarantee.

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!

The first time I used it , it gave me different readings on the same water so I need to figure out how to use it.., ## Frequently Bought Together - iSpring TDS 3-Button Digital Water Quality Test Meter with Temperature Test Function - iSpring Greatwell Reverse Osmosis Membrane 75 GPD 11.75” X 1.75”, Replacement Fits Standard Under Sink RO Drinking Water Filtration System, MC7 - iSpring F9K 1-Year Reverse Osmosis Water Filter Replacement Cartridge Pack w/Alkaline Remineralization Filters for 6-Stage RO Filtration Systems, Without RO Membrane --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hk/products/9456116-ispring-tds2-digital-2-button-tds-meter-with-backlit-lcd](https://www.desertcart.hk/products/9456116-ispring-tds2-digital-2-button-tds-meter-with-backlit-lcd) --- *Product available on Desertcart Hong Kong* *Store origin: HK* *Last updated: 2026-05-29*
