WHAT ARE TOTAL DISSOLVED SOLIDS OR TDS?
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.

Concerning
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.

TDS Meter
I already had a similar meter that was included free with a filter pitcher but the one RKIN offers seemed more robust and also reports water temperature, useful data for when I cook. The other meter will now go into the camper to check n campsight water, but the RKIN will be kept on hand in my kitchen.
