Hanna HI12922 pH/temperature electrode for direct soil

Hanna HI12922 pH/temperature electrode for direct soil

The Hanna HI12922 pH/temperature electrode for direct soil is a Bluetooth®-enabled pH and temperature electrode engineered specifically for direct soil pH measurement, agriculture, and hydroponics. Its conic tip (12 x 12 mm) ensures easy penetration into moist soil, while the triple ceramic junction provides stable measurements even in low-moisture environments.

Moreover, the built-in temperature sensor allows automatic temperature compensation, resulting in more accurate pH readings across varying field conditions. Since it communicates wirelessly through Bluetooth® Smart (Bluetooth 4.0), this electrode pairs seamlessly with the Hanna Lab App for real-time data visualization, calibration, and logging.

Key Features

• Purpose-Built for Soil: The conical tip design is ideal for direct insertion into soil samples and semi-solids.

• Triple Ceramic Junction: Enhances electrolyte flow, especially in low-conductivity samples like soil or compost.

• Integrated Temperature Sensor: Ensures temperature-compensated pH readings without extra probes.

• Bluetooth® Smart Connectivity: Offers a wireless range of up to 10 meters with iPads using iOS 7.1 or newer.

• Hanna Lab App Compatible: Enables advanced data tracking, multi-point calibration, and exportable logs.
