The pocket tester we pull out whenever water quality is the question.
Water pH is one of those readings homeowners rarely think about until it costs them. Acidic water quietly corrodes plumbing and can leach copper and lead from older pipes; alkaline water scales up fixtures and water heaters. You can't see it, taste it, or smell it — but a five-second dip with the right tester tells you exactly where you stand. The Hanna HI98107 pHep is the pocket pH tester we keep on hand for drinking water, well water, aquariums, pools, and ponds.
Why we carry this product
We only sell what we'd use ourselves, and Hanna is a name we already trust in the field. pH is the first thing we check on a water sample because it tells you whether your water is working against your plumbing — and your health. The HI98107 earns its spot for three reasons: two-point automatic calibration keeps it honest over time, automatic temperature compensation means accurate readings whether the water's cold from the tap or warm from a tank, and the waterproof body survives the kind of real-world use that kills lesser meters. It's not a lab instrument, and we won't pretend it is — but for fast, dependable pH checks around the home, it's the one we reach for.

Tight accuracy in a pocket pen.

The PH20 reads the full 0 to 14.0 pH range at 0.1 resolution with ±0.1 pH accuracy — a meaningful step up in precision. Apera's proprietary low-impedance glass-bulb sensor responds fast, and a 180° viewing-angle LCD shows your pH and temperature together so you read the whole picture at a glance.
Calibrates automatically — up to three points.
Calibrates automatically — up to three points.
The PH20 handles automatic calibration at one, two, or three points, so you can match it to how precise your application needs to be. Automatic Temperature Compensation keeps readings honest from 32 to 122°F (0 to 50°C), and a smiley-face stability icon confirms the exact moment a reading settles — no guessing when to record your number. Built-in self-diagnosis flags issues before they cost you a bad measurement.
IP67 waterproof. And it floats.
IP67 waterproof. And it floats.
This is built for real-world use: a full IP67 waterproof and dustproof rating, plus a floatable body so an accidental drop in the pool or tank doesn't end your day. It runs on four standard AAA batteries for up to 2,000 hours of use, with a flashing battery icon when it's time for a swap, and powers down automatically after 8 minutes of inactivity to save charge.
