Hanna HI14142 pH/temperature flat tip electrode

Hanna HI14142 pH/temperature flat tip electrode

The Hanna HI14142 pH/temperature flat tip electrode is a flat-tip pH and temperature electrode designed for measuring pH on surfaces and semi-solid samples such as agar plates, food products, leather, paper, and skin. Its open junction and Viscolene electrolyte prevent clogging and ensure stable, reliable readings even in samples with proteins, oils, or other contaminants.

Thanks to its integrated temperature sensor, the HI14142 provides automatic temperature compensation, improving accuracy across a wide temperature range. Additionally, Bluetooth® Smart (Bluetooth 4.0) connectivity allows seamless wireless pairing with the Hanna Lab App, enabling advanced calibration, real-time data logging, and easy data export.

Key Features

• Flat Tip Design: Perfect for surface measurements on skin, paper, or solid food samples.

• Integrated Temperature Sensor: Delivers precise, temperature-compensated pH readings.

• Open Junction with Viscolene Electrolyte: Reduces clogging and improves electrode performance in semi-solid samples.

• Bluetooth® Smart Connectivity: Enables wireless data transfer with up to a 10 m range.

• Long Battery Life: Operates for approximately 500 hours on a CR2032 lithium battery.
