Handheld TDS meter with a sleek design that's perfect for today's modern kitchen

This TDS meter is the next generation for today's tech-savvy and health-conscience consumer. If you have a reverse osmosis system, how do you know when to change the membrane? The answer is "You don't... unless you have a TDS meter." Everyday we are shocked to hear people ask if their membrane should be replaced and they have no idea of what their water quality might be.

It's magnetic back allows you to store it on your refrigerator or dishwasher door so that you can monitor your water quality on a regular basis.
