HI-12922 HALO® Wireless Soil pH Electrode

The HI-12922 HALO® Wireless Soil pH Electrode is designed to make soil and soil slurry pH testing efficient and straightforward for agricultural professionals and enthusiasts. With Bluetooth Smart (Bluetooth 4.0) wireless technology and full compatibility with the free Hanna Lab App, you can measure pH and temperature directly in soil or slurry and transmit the results wirelessly to your tablet or mobile device—or to the edge® blu meter.

Purpose-Built for Agriculture

The HI-12922 HALO® is engineered specifically for direct soil and soil slurry measurements. Its innovative features make it the ideal solution for field or greenhouse use, including:

• Low-Temperature (LT) Glass: Suitable for measurements from -5°C to 70°C, giving you flexibility to work in varying environmental conditions.
• Conical Glass Tip: The durable, conic (12 x 12mm) tip is optimized for penetrating soils, semi-solids, and emulsions for accurate and reliable pH readings directly at the source.
• Triple Ceramic Junction: The triple ceramic junction in the outer reference cell allows a higher electrolyte flow rate (40 to 50 μL/hour) for greater continuity and faster, more stable results.
• Integrated Temperature Sensor: Built directly into the probe for accurate, automatic temperature-compensated pH readings.
• Refillable Design: Features a refillable probe with a secondary reference chamber filled with HI-7082 3.5M KCl solution for extended use and reduced maintenance costs.
• Glass Body: Chemically resistant glass ensures easy cleaning and excellent heat transfer for rapid equilibrium and stable measurements.
• Bluetooth® Smart Connectivity: Wireless data transmission with up to 10m range, freeing you from cables and enabling real-time readings on your device.
• Status LED Indicator: The LED halo light flashes to indicate probe status, visible even from a distance.
• Easy Battery Replacement: Powered by a CR2032 lithium ion battery providing up to 500 hours of use.
