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

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.

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.

Great

Purchased TDS meter and pH metre on second July 2025. The TDS meter seems to work okay but the pH meter gives faulty and unstable reading. I have done the calibration correctly and also I am using it as per the instructions. The support even during warranty is not available and the customer support number after calling repeatedly does not give any response. The product test three month warranty that is till 1st October 20025 but there is no response from the customer support service. This product should not be bought.

Tds and ph meter both are acurate results packing id 10 of 10 marks

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.

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.

Great combo for serious aquarists. Very useful for a quick read in two water parameters that could serve as an early warning against livestock deaths. Readings are quick and fairly accurate as compared to other traditional methods.
