2025 All-New 4 in 1 Tds Meter Digital Water Tester - Accurate and Reliable TDS EC & Temp(°C,°F) Meter - 0-9999ppm - Professional Testing for Drinking Water, RO/DI System, Aquariums etc

I’ve been using the 2025 All-New 4-in-1 TDS Meter for a few weeks now to check water quality in my aquarium and for general testing around the house, and overall it’s been accurate, reliable, and easy to use. Right from the first test, the readings felt consistent. Whether I was measuring total dissolved solids (TDS), electrical conductivity (EC), or water temperature, the numbers matched what I expected based on past tests with other meters. The ability to switch between °C and °F is a nice touch, and the digital display is clear and readable even in lower light. One thing I appreciate is how simple the device is to operate. There are only a couple of buttons, and once you learn the basics (calibrate, dip, and hold for a stable read), it’s very straightforward. The meter responds quickly, and the readings stabilize in a matter of seconds, which makes testing quick when you’re doing multiple samples. The build feels solid for the price — it’s lightweight but doesn’t feel flimsy, and the protective cap helps keep the sensitive electrodes safe when stored. The digital screen is easy to read, though it doesn’t have a backlight, so if you’re working in dim conditions you might need a light source. A few small things to know: The probe section is a bit compact, so you have to be careful to dip it deep enough for accurate readings, especially in shallow containers. It’s not waterproof beyond the sensing area, so avoid submerging the body of the tester. Overall, this 4-in-1 TDS meter gives you good accuracy and reliable performance at a price that’s very reasonable — great for aquarium hobbyists, water quality checks, or anyone who wants quick insight into water conditions without spending on more expensive lab gear.y

Works well. Easy to use. You’d be surprised at the ppm levels of bottled water.

I’ve been using the 2024 All-New 4-in-1 TDS Meter for a few weeks now, and it’s proving to be a great little tool. It’s easy to use straight out of the box, and I appreciate the quick, accurate readings for TDS, EC, and temperature in both °C and °F. The digital display is clear, and switching between modes is seamless. I’ve tested it on my RO system and it gave consistent results across multiple tests — definitely feels reliable. The auto shut-off and hold functions are also thoughtful additions

This is a great product. It does exactly what it's supposed to do. It works so well it causes me stress when I see my aquarium water high in Tds 🤣

It's very accurate and sensitive water tester. I like to use it for my water filter and it helps a lot of getting me to drink clean water.

I love this meter! I’ve tested everything from bottled water to creek water and then tested with a chemical water tester and the results are always accurate. Super easy to use.

I had my suspicions about my top water at home, and it was in the 500s. FUJI water was in the 140s, other bottle waters in the 70-90s. Just my local water and Ice store their water quality is in the 20s. Excellent tool to have peace of mind.

Very deceiving , you only get one not 2 but it works .
