A TDS meter (aka ppm pen, nutrient tester, tds stick) is an inexpensive and convenient digital tool to instantly check your overall water quality. TDS = Total Dissolved Solids, which is any salt, metal or mineral in the water. With the push of a button, the TDS-4 can tell you your overall water purity level, which will be displayed on the screen in ppm (parts per million). The lower the TDS level, the purer the water, with 0 ppm being pure H2O. The TDS-4 is great for checking your tap water quality, or knowing when to change a filter. (The meter does not test for biological contaminants.) The TDS-4 is a great tool for drinking water, water filtration and purification, hydroponics (test your nutrients), colloidal silver, aquariums, RO/DI systems, pools and spas, and more. ## Features - This TDS tester is ideal for all water purification applications, wastewater regulation, aquaculture, hydroponics, and colloidal silver - ATC (Automatic Temperature Compensation) - The Sleek design of the TDS-4 is perfect for personal or commercial use - Advanced microprocessor technology - Hold Function: Freeze the measurement to view it out of the water. ## Images ![FicBox TDS-4 Pocket Size TDS Tester Meter Without Digital Thermometer, 0-9990 ppm Measurement Range, 1 ppm Resolution, 2% Readout Accuracy - Image 1](https://m.media-amazon.com/images/I/41RNcyF7I5L.jpg) ![FicBox TDS-4 Pocket Size TDS Tester Meter Without Digital Thermometer, 0-9990 ppm Measurement Range, 1 ppm Resolution, 2% Readout Accuracy - Image 2](https://m.media-amazon.com/images/I/61nsS2-cOaL.jpg) ![FicBox TDS-4 Pocket Size TDS Tester Meter Without Digital Thermometer, 0-9990 ppm Measurement Range, 1 ppm Resolution, 2% Readout Accuracy - Image 3](https://m.media-amazon.com/images/I/51Mxb7+hNwL.jpg) ![FicBox TDS-4 Pocket Size TDS Tester Meter Without Digital Thermometer, 0-9990 ppm Measurement Range, 1 ppm Resolution, 2% Readout Accuracy - Image 4](https://m.media-amazon.com/images/I/51NwniCWtAL.jpg) ![FicBox TDS-4 Pocket Size TDS Tester Meter Without Digital Thermometer, 0-9990 ppm Measurement Range, 1 ppm Resolution, 2% Readout Accuracy - Image 5](https://m.media-amazon.com/images/I/515r9Sh6ZaL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ This tester is a good value. *by R***N on Reviewed in the United States πŸ‡ΊπŸ‡Έ on October 6, 2015* I purchased this tester because I was going to change out the filters and membrane on my RO system. I wanted to know the condition of the water (tap water) going in as well as the performance of my system before and after the membrane and filter changes. The tester was compact, easy to use and easy to read. Although it does not provide temperature readings of the liquids you are testing, it does compensate for temperature readings, giving the user more accurate data. The tester came with a black little case to store it in, which was a nice surprise. For the money, I don't think you can beat this tester. 1245 ### ⭐⭐⭐⭐⭐ Works good for ponds *by S***E on Reviewed in the United States πŸ‡ΊπŸ‡Έ on October 15, 2015* Works great and quick! I just hand to learn how to use it properly. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.ar/products/15740776-ficbox-tds-4-pocket-size-tds-tester-meter-without-digital](https://www.desertcart.com.ar/products/15740776-ficbox-tds-4-pocket-size-tds-tester-meter-without-digital) --- *Product available on Desertcart Argentina* *Store origin: AR* *Last updated: 2026-05-23*
