Waterproof Portable pH/Temperature Meter with Stainless Steel pH Electrode HI12963
Imagine this: you walk over to your pool, dip the electrode into the water, and within seconds you can read exactly how your pH and temperature are doing. No more guesswork, no more doubt about the reliability of a test strip — just a clear figure on a large display. That's what this Hanna Instruments HI991001 with the robust metal HI12963 electrode delivers you every day.
This compact, portable meter is built for people who take their water values seriously and want to know them quickly and accurately. You measure pH and temperature at the same time, with a two-button operation so simple you won't need a manual.
Pool water that is truly in balance
A well-balanced pH is the basis of clear, pleasant and healthy pool water. When your pH is right, your chlorine or other disinfection works optimally, the water stays pleasant for skin and eyes, and you prevent limescale build-up or corrosion. With an accuracy of ±0.02 pH and a resolution of 0.01 pH, you know exactly where you stand, so you correct just enough — not too much and not too little. The result: water that looks crystal clear and that you can dive into without worries.
An electrode that can take a knock
The heart of this meter is the combined HI12963 probe with reinforced metal housing, DIN connector and a 1 metre cable. That sturdy housing withstands aggressive chemicals and also helps suppress electrical noise, so your measurement stays stable and reliable. Handy detail: the pull-out junction. If you notice the response time slowing down or the junction getting clogged, you simply pull out a small section to expose a fresh layer. This significantly extends the electrode's lifespan.
Measuring range and calibration
The meter covers a wide pH range from -2.00 to 16.00 pH and measures temperature from -5.0 to 105.0 °C, with automatic temperature compensation so your pH value is always correct, regardless of how warm or cold the water is. Calibration is done automatically at one or two points, with a choice of standard buffers (4.01; 7.01; 10.01) or NIST buffers (4.01; 6.86; 9.18). On-screen calibration labels and a probe condition indicator show you exactly whether everything is still properly calibrated.
Reliable, wherever you measure
Thanks to the IP67 waterproof housing and waterproof probe connection, you don't need to worry about a splash of water or an occasional submersion. You can choose between °C and °F, and the meter switches itself off automatically to save energy. With an exceptional battery life of no less than 1400 hours of continuous use, plus a battery level indicator and low battery detection, you'll never be caught out without a measurement. This way, you can effortlessly keep your pool in top condition season after season.
