High-Precision pH Meter for Water Quality Testing – 0.01 Accuracy, 0-14 Measurement Range

High-Precision pH Meter for Accurate Water Quality Testing

This pH meter offers high precision with an accuracy of 0.01, making it ideal for applications requiring detailed water quality analysis, such as aquariums and swimming pools.

Key Features

• Measurement range: 0-14 pH
• High accuracy: 0.01 pH
• Easy calibration with standard buffers or purified water

Calibration Instructions

Using Standard Buffers

1. Pour standard buffer solutions (6.86, 4.01 at 25°C) into separate clean beakers.
2. Rinse the electrode with one beaker and calibrate with the other to minimize contamination.
3. Power on the device, immerse it in the buffer, and gently shake. Press CAL when the value stabilizes.

Using Purified Water (pH 7)

1. Use two beakers for rinsing and calibration to reduce contamination.
2. Power on, immerse the device in purified water, and press CAL. The device will automatically calibrate to 7 pH.

Important: Calibration should be done at 25°C for optimal accuracy. Use distilled or pure water (pH 7) for calibration, as tap water can be unstable and affect calibration accuracy.

Note: Initial data fluctuation is normal as the device adapts to the testing environment. Ensure the water is still during measurement for accurate readings. Batteries are not included due to logistics restrictions.
