In fact some of paid bottle water was slightly acidic. This device helped in determining the water's PPM / EC levels. In this case the tap water had a higher PPM and EC level than the paid bottle water. Very easy to use, Turn it on and insert it into the water. Read the meter results after it has settled a few seconds. If you are testing your drinking water, this is a handy tool. Since most of our body is made of water, these tests are helping us determine what the best water to put in our body. ### ⭐⭐⭐⭐⭐ Great gadget to have!! *by K***V on Reviewed in the United States 🇺🇸 on May 23, 2018* This is a great gadget to have and very easy to use. I bought it because I wanted to test the filtered water we use from our refrigerator and after testing it I immediately ordered a new filter. Now I find myself testing all the water I drink ever where I go. It's handy that it is small enough that you can just put it in your purse and carry it with you. An added bonus is we also used it to check the water for our aquarium. Definitely recommend. ### ⭐⭐⭐⭐⭐ Awesome water tester *by S***E on Reviewed in the United States 🇺🇸 on May 16, 2018* This tester is great for those moments when you feel like your brita water just doesn't taste the same. When I change my brita filter, the tds meter reads around 20 ppm. After a few weeks I can see that the ppm reads higher. My faucet water is pretty bad so I like to change the filter when it gets to be over 200. I'm glad I bought this handy little gadget. --- ## 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.tn/products/63865637-tds-meter-by-novoblue-2-in-1-digital-tester-pen](https://www.desertcart.tn/products/63865637-tds-meter-by-novoblue-2-in-1-digital-tester-pen) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-07-17*
