Konvio Neer TDS meter and PH Meter combo, tds and ph testers for water testing

I recently purchased the Konvio Neer TDS and pH Meter combo for testing water quality, and I’m very satisfied with the product. Both testers are compact, lightweight, and easy to use. The TDS meter gives quick and accurate readings, helping me monitor the purity of drinking water, while the pH meter is reliable for checking acidity and alkalinity levels. The digital display is clear, and calibration is straightforward. This combo is especially useful for households, aquariums, and even small labs. Overall, it’s a cost‑effective and dependable solution for anyone concerned about water safety.

Product is good, value for money, good for basic research Students and laboratory work, easy to use, with proper guide, good case, pH value fluctuates slightly but nearly perfect readings, reading speed is slow but good at this low price range. Portable.

Good product, packed properly and delivered in time.

TDS meter works well but ph meter is not working and its used product, i ordered for planted aquarium initially i checked only tds meter after three weeks while using ph meter its dead my return window is closed now , lost my money

Very handy and accurate

Unable to caliberate the PH meter as stated in your guide. Till date product with me. Nobody has come to collect it back and no such intimation. Refund is pending since one month

I purchased both the digital pH meter and the TDS meter, and I’m very satisfied with their performance. The pH meter is straightforward to use, though calibration takes a little care. It appeared to be pre-calibrated out of the box, as it gave accurate readings for lemon water and RO water even before calibration. Once calibrated, the response time improved further, and the measurements were quick and stable. The TDS meter works flawlessly and provides instant results. I tested it by adding baking soda to RO water, and the ppm values increased immediately as I mixed, confirming its accuracy and responsiveness. Overall, both meters are reliable, easy to use, and deliver accurate results. A great value for anyone who needs quick and dependable water testing tools.

About a decade back I had Henna made tds and pH metres. They have become too old and require calibration. The I thought I will buy a new pair instead of calibrating them. Konvio noor is a reasonably priced tool. I don't have to tell you the need for checking the tds and pH of drinking water. I am particular that the water is slightly basic and not devoid of minerals. I am not using RO. I am using cauvery river water and is purified using filtration and UV light. I found the TDs value is 185 and pH is 7.6. I am happy with this. PH metre is supplied in a plastic box and TDs metre in a plastic cover. I wold have appreciated a single plastic box for both with partitions or two separate boxes for convenience and safe storage. The name konvio noor is a sticker. I don't know why the brand name is not printed on plastic. This gives a little cheap look to the product.
