Digital pH Pen Meter – Accurate Water Quality Testing Made Easy

The Portable Digital pH Pen Meter is a compact, precision instrument designed for fast and accurate measurement of pH levels across a wide range of applications — from aquariums and aquaculture to food safety, hydroponics, and domestic water testing. Whether you’re maintaining stable water parameters for marine life or ensuring the right pH balance in your everyday water use, this handheld device delivers reliable results you can trust.

Key Features

1. Wide Measurement Range
This digital pH tester offers a full measurement range from 0.00 to 14.00 pH, making it suitable for both acidic and alkaline environments. From freshwater tanks to reef aquariums and even food or beverage testing, it’s an all-purpose tool for accurate monitoring.

2. High Accuracy and Resolution
With a precision of 0.01 pH, the meter detects even the smallest changes in pH levels. This high-resolution accuracy ensures that aquarists and water quality professionals can maintain optimal conditions where stability is essential.

3. Automatic Temperature Compensation (ATC)
Equipped with automatic temperature compensation, the pH pen adjusts readings based on water temperature between 0°C and 60°C, ensuring accurate measurements even in fluctuating conditions. This feature is especially valuable for aquarium and aquaculture environments, where temperature shifts can affect pH readings.

4. Three-Point Automatic Calibration
The three-point calibration system (pH 4.01 / 6.86 / 9.18) guarantees consistent accuracy. Calibration is simple — just use the included buffer powders to prepare your solutions, immerse the electrode, and follow the on-screen prompts for automatic adjustment.

5. Large Digital Display
The meter’s clear LCD screen displays real-time pH values with excellent visibility, allowing for quick and easy data reading. The intuitive design makes it ideal for beginners and professionals alike.

6. Durable and Portable Design
Weighing just 49 g and measuring 15.5 × 3.1 × 1.7 cm, this pH meter is lightweight, compact, and easy to carry anywhere. Its ergonomic build ensures a comfortable grip during testing, while the included storage box keeps the unit and accessories organized and protected.

How to Use the pH Pen Meter

1. Calibrate using the provided pH buffer powders before first use or after long storage.

2. Rinse the probe with distilled water and gently dry it.

3. Immerse the probe tip in the test solution — whether it’s aquarium water, tap water, or a food sample.

4. Wait for stability. The readings will fluctuate slightly at first as the device adapts to the sample’s temperature. Within about one minute, the numbers will stabilize — this is your final pH value.

5. Record the reading and rinse the probe again before storing.

Note: If the water surface moves or vibrates during testing, readings may jump slightly. This is completely normal. Allow the water to remain still for the most accurate results.
