It turns clear water into a number you can actually read
It looks clean. It tastes fine. But dissolved minerals are invisible — calcium, magnesium, sodium, mineral salts — and every water source carries a different load.
Your water might read 5 ppm or it might read 450. Both glasses look identical. One dip and you'll know the difference.

It answers the question you ask every time you fill a glass
You drink it every day. You cook with it, brew coffee with it, give it to your kids. And every single time, you're trusting that what you're drinking is the same as yesterday.
It might be. It might not. Mineral content shifts with seasons, supply changes, and where you are. One dip turns trust into a number.

It uses the same technology as lab meters
The two titanium alloy prongs at the tip don't rust or corrode like the cheap steel tips on budget meters. Your readings stay accurate — not just day one, but year after year.
±2% accuracy across a 0–9990 ppm range. The same titanium alloy tips used in meters that cost ten times more.

Remove the cap, press the button, dip. The backlit LCD locks a reading in under two seconds. No app, no phone, no lab.
Flip it over. The color-coded TDS Guide on the back tells you exactly what your number means — from excellent to elevated.
