TDS Meter Digital Water Tester - Self-Calibrating for Accurate Results - Water Quality Tester Ideal for Drinking Water, Hydroponics, TDS and PPM Measurement

⭐⭐⭐⭐⭐ This TDS meter is an absolute must-have! It's incredibly easy to use—just dip it in water, and you get an instant reading. The accuracy is spot-on, and the added features like temperature measurement make it even more versatile. I’ve used it to test drinking water, aquariums, and even my hydroponic setup, and it’s been reliable every time. The compact design and durable build are a bonus, making it perfect for on-the-go testing. Highly recommend this to anyone who cares about water quality!

first one lasted about a year before misreading. Could have been the batteries but they are about the same price as the unit itself with batteries. Just bought another one. Works well doesnt need to be calibrated.

Works very well, easy to use.

Seems to work pretty well but need to go from The Meters PPM to the local water companies measurement to determine hardness.

Measurement max depth not 2". Should be 1-3/8" Also, nothing in package telling what reading number means.

I rarely write reviews but this tester really was a great bargain and worked well. It show that water from my under counter reverse osmosis system produces water with 15tds and my well water has 85tds. Very reassuring to know. I am about to get a new whole house water filtration system and I needed this information.

I should have looked a little more. It does a quick reading but there is nothing in the provided sheet that tells you what is considered a good vs bad number. If I can get this info, I will revise my rating as it arrived quick and gives a super quick reading. I tried the water in various containers and it gave same reading. I also bought two and both gave consistent readings. I just don’t know how to interpret them and the little pamphlet didn’t help :( UPDATE- the seller reached out almost automatically. Great customer service!! Provided the below, so hope this helps future buyers: Thank you for reaching out to us. The main reason we do not provide a specific chart with the product is that the intended use of TDS meters can vary significantly from one customer to another. These meters are not only used for drinking water, but also for applications like aquariums, water softening systems, and mainline filtration measurements. Because of this wide range of use cases, it is difficult to provide a single standard reference chart that suits everyone. However, we appreciate your feedback and will definitely consider working on helpful guidelines for users. That said, here is a general idea of how TDS (Total Dissolved Solids) values are commonly interpreted: -0 to 50 ppm: Very low TDS – This range is usually achieved through reverse osmosis or distilled water and is often used in laboratory or medical applications. -50 to 150 ppm: Excellent – Considered ideal for drinking water; usually indicates good taste and cleanliness. -150 to 250 ppm: Good – Acceptable for most people; moderate mineral content. -250 to 350 ppm: Fair – Still drinkable, but may start to affect taste depending on sensitivity. -350 to 500 ppm: Poor – Approaching the upper limit for drinking water quality; may not be desirable. -Above 500 ppm: Not recommended for drinking – Exceeds the EPA’s recommended limit for TDS in drinking water and may indicate the need for filtration or treatment. Please note that TDS meters measure the total concentration of dissolved solids but do not indicate the specific types of contaminants present. For a full analysis of water safety, further testing may be needed.

Excellent product easy to use and very accurate.

I’ve used this TDS meter for measuring coffee extraction, checking my aquarium water, and testing my RO water system, and it has been consistently accurate. It’s simple to use, gives quick readings, and consistent results. A handy tool whenever working with water or just need more stats to work with

It's a brilliant item thank you.

Works surprisingly well for price

Works as advertised so far.

4 stars as there is nothing to show what the readings relate to, if it is safe to drink or not there is no chart included. Otherwise good product
