Labtron Portable pH Meters offers handheld measurement of hydrogen ion concentration of acid and alkaline solution. They are equipped with durable, waterproof casings to withstand harsh conditions during measurement. Their LCD displays are clear and easy to read, even in low-light outdoor conditions. They are designed to be ergonomic, making them comfortable to hold during extended use. Our Portable pH Meter provide readings for agriculture, water testing, and laboratory analysis.






Our Portable pH Meter is powered by AA batteries (1.5V), making it convenient for portable and field use. The battery-operated design eliminates the need for an external power supply and supports features like auto power-off and low-voltage alerts to optimize battery life and ensure reliable operation.
Labtron’s Portable pH Meters have an in-built microprocessor chip that enhances functionality and measurement accuracy. It enables advanced features such as automatic calibration, automatic temperature compensation (ATC), data storage, function setting, auto diagnostics, auto power-off, and low-voltage alarm. These intelligent functions improve ease of use, reduce manual errors, and ensure consistent, reliable performance in various testing environments.
Our Portable pH Meters have an auto recognition feature that allows the device to automatically identify and match calibration buffer solutions from up to 25 standard options (including Europe, USA, NIST, and China standards). This eliminates manual input errors during calibration, speeds up the process, and ensures higher accuracy and consistency across different testing scenarios. It also supports 1, 2, or 3-point calibration, making the meter highly adaptable and user-friendly.
Labtron’s Portable pH Meters is equipped with a large LCD screen that offers clear and easy-to-read measurements. It includes a controllable white backlight, allowing users to view readings comfortably even in low-light or outdoor environments. The backlight can be turned on or off manually, helping conserve battery power when needed. The display shows pH, temperature, mV values, and calibration status—all on one screen for efficient monitoring.
Our Portable pH Meter comes with a complete set of standard accessories to ensure accurate and convenient use. It contains a pH electrode for precise pH measurement. The temperature Probe enables automatic temperature compensation. Additionally, pH Buffer Solutions are used for calibration to maintain accuracy.
