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

A nice and accurate TDs and pH meyre

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.

According to price it's good.

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.

Works perfectly

This is an amazing product.It gives immediate and accurate results.Very good.And what is the best part is that you get TDS meter along with it.So it's a very good deal

5 star for TDS meter. Zero star for pH meter.

TDS meter is very good, recommended. pH meter is completely faulty. Doesnt calibrate properly at all. And even after completing calibration somehow, it gives wrong reading. (If my RO purified water had a pH of 10.5 to 11 as the pH meter shows, heavens help us). Im a Chemistry graduate, so I do know a thing or two about pH and its meters. Pls buy only the TDS meter standalone. For pH meter, try some other brand. Trying to get replacement or refund for the Ph meter but not sure if it will be allowed since I already used the sample calibration sachets. Its tricky. Without using the sachet, you cannot calibrate. And if you calibrate and product is faulty, you cant get replacement cos you used up the sachets. Catch 22. Wil give it a try through amazon and update.

Nice product

Great

Check the condition before sending

Please check the batteries before sending. Tds is working. But ph meter did not even turn on. I am guess it is because of battery

Reliable water testing tools- fast and precise

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.

All good

Everything is good
