4-in-1 Hydrogen Water Tester

pH, H2, ORP & Temperature Meter with ATC & Backlit Display, Dual ppb/ppm Modes, 3-Point Calibration for Drinking Water, Aquariums, Pools & Home Brewing 💧 4-IN-1 PRECISION TESTING — Measures pH, hydrogen (H2), ORP, and temperature simultaneously. Hydrogen range 0–2400 ppb / 0.001–2.400 ppm gives you an accurate read on your water's actual hydrogen concentration — not a guess. 💧 LAB-GRADE pH ACCURACY — High-sensitivity glass probe covers the full 0–14 pH range with 0.01 resolution. Use it for hydrogen water, pools, hydroponics, aquariums, koi ponds, home brewing, well water, RO water, and more. 💧 SMART ORP MONITORING, ANY CONDITION — Automatic temperature compensation (ATC) keeps readings accurate even as water temperature shifts, and the HD backlit LCD makes it easy to read in low light. Auto-off after 5 minutes of inactivity preserves battery life. 💧 3-POINT CALIBRATION FOR TRUE ACCURACY — Calibrates at 4.00 / 7.00 / 10.01 for precise pH readings every time. Arrives factory-calibrated and ready to use right out of the box — no setup hassle. 💧 TWO MODES, ONE-TOUCH CONTROL — Switch instantly between ppb and ppm with a short press of the MODE/CAL button. Use HOLD/TEMP to lock a reading in place for easy, accurate recordkeeping — press again to release. 💧 BUILT FOR EVERYDAY USE — Compact, lightweight, pocket-sized design goes wherever you need to test — kitchen counter, pool deck, fish tank, or brew kettle. Description Is your water actually delivering the hydrogen content it promises? This 4-in-1 Hydrogen Water Tester takes the guesswork out, giving you precise, real-time readings for pH, hydrogen (H2), ORP, and temperature — all from one compact device. Built with a high-sensitivity glass pH probe (0–14 range, 0.01 resolution) and a hydrogen sensor accurate to 0–2400 ppb / 0.001–2.400 ppm, this tester is equally at home checking your hydrogen water, monitoring a swimming pool, dialing in a hydroponic setup, keeping an aquarium healthy, or nailing the pH for beer, wine, or kombucha brewing. Automatic temperature compensation and a backlit HD display mean you get consistent, reliable readings no matter the water temp or lighting. Switch between ppb and ppm modes with one button press, lock in a reading with HOLD/TEMP, and rely on 3-point calibration (4.00/7.00/10.01) for lab-level accuracy. Factory-calibrated and ready to use out of the box, with auto power-off to save battery between uses. Compact, portable, and built for daily testing — this is the water quality tool for anyone serious about knowing exactly what's in their water. AVAILABLE FOR SHIPPING IN CANADA AND USA
