Nothing In Your Kitchen Is Measuring Your Water

Not the filter. Not the pitcher. Not the little light that turns red on schedule whether the cartridge died last month or is still fine. Dip Hydrova in and something finally is.

Know the day your filter dies, not three months later

Most people have never checked. The ones who do are rarely surprised, and not in the direction they expected

Dip. Read. Compare.

Dip The Probe

Everything dissolved in your water carries a charge. Two electrodes read it the second the probe goes in.

Read The Number

About three seconds later your reading appears in parts per million, backlit and clear in a dim kitchen.

Compare The Gap

Hold the reading, test the next glass. Tap against filtered, filtered against bottled. The gap is your answer.

Proof Your Filter Still Works

Test your tap, then your jug. If the numbers barely move, that cartridge died weeks ago and the light never told you.

See What The Premium Buys

Evian reads around 345 ppm. Plenty of taps read lower. Dip Hydrova in both and find out what you've been paying for.

Catch It Before It Costs You

RO and DI water should read zero. When it creeps up, your resin is spent — and you'll know before your fish do.

My filter was dead and I had no idea

Tap read 341. Filter jug read 336. That cartridge went in six weeks ago and the light is still green. Ordered a pack of replacements the same afternoon. Tap read 341. Filter jug read 336.

Settled an argument in our house

My wife swears by the bottled stuff. I tested it against the tap and the bottle came out higher. She still buys it but she's stopped telling me the tap's bad. My wife swears by the bottled stuff.

Finally know when to change the resin

Keep a reef tank and RO output crept from 0 to 4 without me noticing. Caught it before it went in the tank. Paid for itself immediately.

An eye opener

Read the screen fine even in a dim kitchen. Tested the tap, the jug, the bottled water in the fridge. Not what I expected on any of them. Read the screen fine even in a dim kitchen.

Everything You Need To Know

No, and anyone selling you one that claims otherwise is lying to you. Hydrova measures dissolved solids — the minerals, salts and metals your water carries. That makes it excellent at spotting a failing filter or a change in your water. It's a comparison tool, not a lab test.

On its own, not much — which is why every order includes our Water Reading Card. A low number isn't automatically good and a high one isn't automatically bad. Evian reads around 345 ppm. The useful part is the gap between two readings, not either number alone.

None. Pull the cap, dip the probe, read the screen. Your first result comes within seconds of opening the box.

Tap, filtered, bottled, well, aquarium, hydroponic, pool. If it's water you care about, Hydrova reads it — which makes comparing sources easy.

Accurate to within 2% and factory calibrated, so the first reading is one you can rely on. Cheap pens drift and leave you trusting a number that's already wrong.

Most of them arrive uncalibrated, and an uncalibrated meter is worse than no meter — it gives you a confident wrong answer. Hydrova ships calibrated, and comes with the card that tells you what your reading means. Nobody else gives you the second part.

No. Buy it once, it's yours. The only thing you'll ever replace is a coin battery.

Send it back within 90 days for a full refund, as long as it's in its original condition with the packaging.
