The lower the TDS level, the purer the water. If TDS value is above 40, normally it indicates the water is very likely unsuitable for drinking, and hence the backlight of the LCD will turn out to be red while the test result of TDS is above 40. However, the water with TDS value below 40 does not necessarily mean it is drinkable since there are various factors (e.g. bacteria amount) would determine whether the water is safe or not. Automatic Temperature Compensation (ATC) Function Since TDS value would be affected by temperature, this meter is equipped with Automatic Temperature Compensation (ATC) function for the highest accuracy purpose. SpecificationsMeasuring Range: TDS: 0 - 9999 ppm (parts per million) Conductivity: 0 - 9999 µs/cm Degrees Celsius: 0 - 99°C Degrees Fahrenheit: 32 - 210°F Accuracy: ±2% F.S Battery: CR2032, DC3V; 230mAh Working Temperature: 32 - 122°F Net Weight: 1.45oz(41g) Size: 6.39 x 1.16 x 0.64 inches How to Use Step 1: Take off the protective cap and press ON/OFF button Step 2: Immerse the meter electrode into the solution and gently stir Step 3: Wait for the reading to stabilize and check the reading Step 4: After finishing, clean the electrode by pure or distilled water and dry it before replacing the cap Step 5: Press the ON / OFF button for 2 seconds to turn off manually Warranty Policy - Industry-leading 12-Month Money Back Warranty - After-sale Service: support@sonkir-mall.com ## Features - Accurate and Reliable: This advanced meter features Automatic Temperature Compensation(ATC) which means it automatically compensates for solution temperatures within a range of 32～122℉, and is equipped with a high-quality titanium alloy probe to ensure you get a accurate and reliable reading without any worry - 3-in-1 Function: It is designed to test TDS(Total Dissolved Solids) and EC(Electrical Conductivity) of water for the purpose of purity. Temperature of water could also be examined. Measuring range: TDS: 0 - 9999 ppm; conductivity: 0 - 9999 µs/cm; temperature: 32 - 210°F/ 0 - 99°C; accuracy: ±2% F.S - LCD Backlight Design: The meter uses low-power backlight technology to easily test water at night and in dark places. In addition, it can also be used to distinguish between drinking water and non-drinking water. Red backlight (ppm>40) means this is non-drinking water - Easy to Use: Turn on the TDS meter and gently stir the water, then a stable reading will automatically lock on the LCD within seconds. The meter will be switched off automatically while it is not in use for 2 minutes - Wide Applications: It is widely applied to science laboratory, school education, commercial manufacture, industrial pollution control, agriculture etc. It can be used to test the standard of household drinking water, RO system, swimming pool, aquarium and other related areas ## Images ![TDS Meter, Sonkir 3-in-1 TDS/EC/Temp Meter, Digital Water Quality Tester for Drinking Water Purity Test, Swimming Pools, Aquariums, Hydroponics, Measure 0-9999ppm (Purple) - Image 1](https://m.media-amazon.com/images/I/41uFXG2amGL.jpg) ![TDS Meter, Sonkir 3-in-1 TDS/EC/Temp Meter, Digital Water Quality Tester for Drinking Water Purity Test, Swimming Pools, Aquariums, Hydroponics, Measure 0-9999ppm (Purple) - Image 2](https://m.media-amazon.com/images/I/51G0smV9yBL.jpg) ![TDS Meter, Sonkir 3-in-1 TDS/EC/Temp Meter, Digital Water Quality Tester for Drinking Water Purity Test, Swimming Pools, Aquariums, Hydroponics, Measure 0-9999ppm (Purple) - Image 3](https://m.media-amazon.com/images/I/410qIT+ykQL.jpg) ![TDS Meter, Sonkir 3-in-1 TDS/EC/Temp Meter, Digital Water Quality Tester for Drinking Water Purity Test, Swimming Pools, Aquariums, Hydroponics, Measure 0-9999ppm (Purple) - Image 4](https://m.media-amazon.com/images/I/51U4uJaQXjL.jpg) ![TDS Meter, Sonkir 3-in-1 TDS/EC/Temp Meter, Digital Water Quality Tester for Drinking Water Purity Test, Swimming Pools, Aquariums, Hydroponics, Measure 0-9999ppm (Purple) - Image 5](https://m.media-amazon.com/images/I/51qwDI2XjVL.jpg) ## Customer Reviews ### ⭐⭐⭐ Read this comparison first *by L***E on Reviewed in the United States on January 6, 2019* I bought “different” 3 tops rated TDS testers from Amazon. Two of them(the white and purple In photo ) just branded differently, but made from the same manufacture in China. The build quality is okay. The reading is somewhat accurate(maybe a little higher). The biggest problem is the battery not user replaceable. If this is what you Looking for,Just get the one with best price.The TDS-EZ (blue one in photos )is a little more expensive, but the build quality is better(design in U.S.A & Korea, made in India). And the battery can be easily replaced.WarrantyTDS-EZ 2 years (blue)Lxuemlu 18 month (white)Sonkir 12 month (purple ) ### ⭐⭐⭐⭐⭐ Help us a lot *by S***S on Reviewed in the United States on December 26, 2018* This tester makes me know that the original water in my home was 348 ppm when it was not. However, the filtered water in my home was only 33 ppm. This allows me to drink the filtered water at ease. I lent this tester to my friend, and he found that his filtered water was up to 200 ppm. My friend would buy the filter we current used. They have new twins in their family and they need very clean water just now. Thanks to this filter, my friend can improve his water quality. ### ⭐⭐⭐ I Question Its Accuracy *by F***I on Reviewed in the United States on March 19, 2019* Compared to my professional TDS / Conductivity meter this one reads low all the time. --- ## 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.pl/products/89502046-tds-meter-sonkir-3-in-1-tds-ec-temp-meter](https://www.desertcart.pl/products/89502046-tds-meter-sonkir-3-in-1-tds-ec-temp-meter) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-05-07*
