4-in-1 pH Meter: GISNPA pH tester measures pH, ORP, H2 and temperature simultaneously, providing you with comprehensive information on water quality. Perfect for measuring drinking water, swimming pools, hydroponics, aquariums and more. Accurate H2 Water Tester: The H2 tester provides two test modes (ppb/ppm), ensuring it meets your needs whether you prefer ppb or ppm mode. Switching between ppb and ppm modes is effortless with a quick press of the MODE/CAL button. 3-Point Calibration: The pH meter features a high-sensitivity glass probe, offering a complete measurement range from 0 to 14 pH with a remarkable 0.01 pH resolution. To ensure measurement accuracy, our pH meter employs a meticulous three-point calibration process, which involves precise adjustments using pH solutions at 4.00, 6.86, and 9.18. Our ORP and H2 meters come pre-calibrated for your convenience. Automatic Temperature Compensation: Our digital pH meter is equipped with automatic temperature compensation, ensuring highly accurate readings despite temperature variations. Unlike conventional pH meters limited to a range of 0°C to 50°C, ours offers a broader operating range from 0°C to 60°C (32°F to 140°F). This extended range effectively minimizes potential errors caused by fluctuating liquid temperatures, thereby enhancing the precision of pH measurements. Automatic Power-Off Function and Backlit Display: Our pH meter includes an automatic power-off feature, which conserves power by turning it off after 5 minutes of inactivity. Additionally, the pH meter is equipped with a green backlit LCD, ensuring that measurement results are clearly visible in all conditions.

GISNPA 4-in-1 pH ORP H2 Tester for Drinking Water

Accurate pH Measurement:

Ensure your drinking water falls within the optimal pH range of 6.5 to 8.5 for purity and taste. With a high-sensitivity glass probe and 0.01 pH resolution, our tester provides precise pH readings to help you make informed decisions about your water consumption.

H2 Measuring:

Beyond drinking water, our H2 Measuring solution is suitable for analyzing h2 content in various liquid sources, including h2 water generators, filtration systems, and more. Explore the potential of hydrogen-rich hydration across different contexts.

Antioxidant Properties Assessment:

Evaluate the antioxidant properties of your water with the ORP (Oxidation-Reduction Potential) meter. Negative ORP values indicate potent antioxidant effects, neutralizing free radicals and promoting overall health. By selecting water with negative ORP, you can maintain the antioxidant balance of your body.

User-Friendly Design:

Designed for ease of use, our tester features a user-friendly interface with intuitive controls. The backlit LCD screen ensures clear visibility of measurement results in any lighting conditions, while the automatic power-off function conserves battery life for prolonged use.

Versatile Applications:

Beyond drinking water, our tester is suitable for testing various water sources, including swimming pools, aquariums, and hydroponic systems. Whether you're a health-conscious individual, a hobbyist, or a professional, the GISNPA 4-in-1 pH ORP H2 Tester is your trusted companion for water quality analysis.
