Achieve perfect balance with the HABOTEST HT631A/B Digital pH Meter. This advanced, professional-grade pH tester delivers laboratory-quality accuracy in a portable and easy-to-use device. Whether you're a serious gardener, an aquarium hobbyist, a pool maintenance professional, or simply concerned about your water quality, the HT631A/B provides the reliable data you need to make informed decisions.

From ensuring optimal nutrient uptake in your hydroponic system to maintaining a healthy environment for your fish, precise pH control is critical. The HABOTEST HT631A/B is your essential tool for mastering your medium.

• High Accuracy & Resolution: Experience exceptional precision with a measurement range of 0.00-14.00 pH and a resolution of 0.01 pH. This high level of accuracy ensures you get trustworthy readings for even the most sensitive applications.
• Automatic Temperature Compensation (ATC): Eliminate reading errors caused by changing water temperatures. The built-in ATC feature (0-50°C / 32-122°F) automatically adjusts the pH reading to provide a stable and accurate result, regardless of the sample's temperature.
• Easy Calibration & Stability: Ensure long-term accuracy with a simple 2-point calibration using standard buffer powders (not included). The sensitive electrode probe provides quick readings that stabilize rapidly, saving you time and effort.
• Large, Clear LCD Display: Read your measurements with ease. The oversized digital screen clearly shows the pH value, temperature, and calibration indicators, even in low-light conditions.
• Durable & Portable Design: The built-in electrode is reliable for repeated use. Its compact and lightweight design, often accompanied by a carrying case (model dependent), makes it the perfect meter for testing on the go—take it to your greenhouse, fish tank, or anywhere else.
• Automatic Power Off: Preserve battery life with the smart auto-shutoff feature, ensuring your meter is always ready when you need it.

• Hydroponics & Gardening: Monitor nutrient solution pH for maximum plant health and yield.
• Aquariums & Aquaculture: Maintain a stable and safe pH level for freshwater and saltwater fish.
• Swimming Pools & Spas: Keep water chemistry perfectly balanced for safety and comfort.
• Drinking Water & Home Use: Test tap water, filtered water, or bottled water.
