I get annoyed by water bottles hanging around the house, bottles being drunken half way and toast in the trash, etc, all these made me decide to get a reverse osmosis water filtration system, it may not be cheap to operate when you factor in the price for filters replacement so to expand my filters life span I like testing my water frequently using a TDS meter and when the water quality from the reverse osmosis filtration system degrades I know it's time for descaling my counter top unit. This TDS meter is very easy to use, practical, works well, durable and you get a reading instantly. This is a very good option if you are looking to test your home water. Review: Works well and is easily replaceable - I’ve owned dozens of PPM/EC pens, meters and testers over the decades and this is the meter recommend for PPM. It’s inexpensive and accurate enough for most homeowners or hobbyist. This has good clear readability and easy operation. Also just a coin cell battery so it’s light. PPM Meters all share one flaw — they are fragile and break easily! Expensive meters break just as quickly and easily as the inexpensive pens. They just aren’t buy it for life products. A budget meter will give up some accuracy compared to more expensive meters on the market but, the budget meter is still plenty accurate for a home owner/hobbyist. When it fails after a year or two, throw it out and buy a new one. My only complaint is that it doesn’t have a loop to attach a string to so I could hang it from a hook when not in use. ## Features - ✔UPGRADED MULTIFUNCTIONAL WATER TESTER: Hofun 3 in 1 TDS Meter, Electric Conductivity Meter & Temperature Meter features the most updated technology.

It’s inexpensive and accurate enough for most homeowners or hobbyist. This has good clear readability and easy operation. Also just a coin cell battery so it’s light.

My only complaint is that it doesn’t have a loop to attach a string to so I could hang it from a hook when not in use. ### ⭐⭐⭐⭐ Affordable and Efficient Water Quality Testing *by S***K on August 22, 2024* I bought the TDS Meter to measure the TDS of my RO filter, and it’s been quite useful. For the price, it offers excellent value—combining TDS, EC, and temperature measurements in one device. The large backlit LCD display makes it easy to read, even in low light, and the quick and simple one-button operation is a real convenience. However, I’ve noticed that the standard for indicating water quality with green for <40ppm and red for >40ppm might not align with all standards I’m familiar with. Despite this, the meter still effectively serves its purpose for my needs. Overall, it’s a reliable tool for monitoring water quality. Also, I feel the meter is a bit bulky for its functionality. ## Frequently Bought Together - TDS Meter, 3 in 1 TDS, EC & Temperature Meter, Drinking Water PPM Meter, Digital Water Testing kits, no Installation Needed - 2024 All-New pH Meter for Water - High Accuracy Digital pH Tester (0.01 Precision) with UL Certification and 3 pH Calibration Powders - Ideal for Home Water, Hydroponics, Aquariums, Pools, and More - 2024 All-New 4 in 1 Tds Meter Digital Water Tester - Accurate and Reliable TDS EC & Temp(°C,°F) Meter - 0-9990ppm - Professional Testing for Drinking Water, RO/DI System, Aquariums etc --- ## 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.ie/products/86761200-digital-tds-meter-hofun-3-in-1-tds-ec-temperature](https://www.desertcart.ie/products/86761200-digital-tds-meter-hofun-3-in-1-tds-ec-temperature) --- *Product available on Desertcart Ireland* *Store origin: IE* *Last updated: 2026-08-15*
