Turn it on. Dip the tip into water. Wait for the number to stop jumping around. That’s it. No buttons, no rituals. Some meters have a “hold” button, but honestly, you don’t even need it. Read the number, wipe it off, move on with your life.
Just don’t drop it in your coffee. Or your fish tank. Or your cup of existential dread. It’s not waterproof—or soul-proof.

The big question: Should you buy one?
It depends. If you’re a casual human who just drinks tap water and doesn’t care? Skip it. But if you’re curious, if you’re a hobbyist, or if you’re the type who tests their pool water with a lab coat? Grab one. They’re like $15. That’s less than a fancy lunch.
You’ll suddenly want to measure everything. The puddle outside. Your buddy’s mysterious basement swamp. The water from that old garden hose. It’s a gateway obsession, I won’t lie.
