The Hanna pH Electrode HI1131B is a refillable pH probe designed for accurate pH measurement in various laboratory and field applications. Some of its key features include:

1. Refillable Design: This electrode has a refillable reference solution, which helps maintain the electrode’s performance over time. Refilling the junction with the proper electrolyte solution ensures consistent and accurate measurements.
2. General Purpose Use: The HI1131B is commonly used for general laboratory, educational, and industrial applications. It is suitable for testing a wide range of solutions and samples.
3. Glass Body: It typically features a durable glass body with a built-in junction for proper electrolyte flow, helping to maintain consistent readings.
4. Ag/AgCl Reference: The electrode uses an Ag/AgCl (silver/silver chloride) reference system, which is commonly found in pH electrodes due to its stability and reliability.
5. High-Temperature Glass Formulation: It is designed to operate within a certain temperature range (usually around 0°C to 80°C), making it versatile for various environments.
6. Compatibility: This pH electrode is compatible with most pH meters, especially those made by Hanna Instruments.
7. BNC Connector: The HI1131B uses a BNC connector. BNC connectors allow for quick and easy connection to any pH/ORP meter or transmitter.
8. Spherical Glass Tip: The spherical-shaped tip design allows for a wider area of contact with the sample for faster measurement, making it ideal for general laboratory use.
9. Maintenance: Proper maintenance of the electrode, including regular refilling and cleaning, is essential for long-term accuracy and performance.
