Total Dissolved Solids Or TDS is a measure of the dissolved combined content of all inorganic and organic substances present in a liquid. TDS is sometimes referred to as parts per million (ppm). You can test water quality levels using this digital TDS PPM meter.

Primary sources for TDS in receiving waters are agricultural & urban runoff, clay-rich mountain waters, leaching of soil contamination, & point source water pollution discharge from industrial or sewage treatment plants.

TDS Meter works well

It performs as indicated by the instructions. It's a useful tool for TDS measurements.

Happy with my TDS meter.

It is very helpful when testing for TDS and temperature prior to putting fresh water into the U1 filtration system. I also do a before and after test for various chemicals with a test kit I purchased elsewhere. Combined with the TDS testing device, i feel confident that my water is properly filtered. I'm very lucky to have a low TDS count for my fresh water.

Based on the high quality craftsmanship of your RO Zero Installation Water Purifier I just purchased, I was surprised at the low quality craftsmanship of the TDS Meter. Not only is the grammar and punctuation on its packaging suspiciously atrocious, but the meter itself appears to have been previously used, or improperly cleaned prior to its packaging. There was a brown residue on the inside of the meter cap, and considering its function, I didn’t feel comfortable putting it in my freshly purified RO water to test it out. It is commendable that your company is giving them away for free if the customer is willing to pay for its shipping, but I fear they will do more harm than good for your company’s overall image and reputation.
