Hanna HI11103 Gel Filled pH Electrode

Hanna HI11103 Gel Filled pH Electrode

The Hanna HI11103 Gel Filled pH Electrode and HI1110B are general-purpose combination pH electrodes designed for reliability and ease of use in laboratory and field environments. These electrodes feature a gel-filled reference system, a spherical tip for universal sample contact, and a single ceramic junction that provides stable readings in a wide variety of aqueous samples. While the HI11103 includes a built-in temperature sensor and amplifier with a Quick Connect DIN connector, the HI1110B model offers standard connectivity via a BNC connector.

Key Features

• Gel-Filled Electrolyte: Unlike refillable electrodes, the HI11103 and HI1110B feature a maintenance-free gel electrolyte, making them ideal for routine and continuous pH monitoring without the need for electrolyte replenishment.

• Single Ceramic Junction: With a flow rate of 15–20 µL/h, the junction ensures stable measurement in low-viscosity aqueous solutions. This design simplifies maintenance while still offering solid performance.

• Low Temperature (LT) Glass: Optimized for operating temperatures from 0 to 80°C, the LT glass formulation ensures fast response and stability in typical laboratory and environmental testing conditions.

• Spherical Tip (9.5 mm Diameter): Offers consistent contact with both flat and curved surfaces, providing versatility for testing beakers, flasks, and standard lab containers.

• Connector Options:

  • HI1110B: Equipped with a BNC connector for compatibility with most standard pH meters.

  • HI11103: Features a Quick Connect DIN connector with built-in temperature sensor and amplifier, providing temperature-compensated readings and greater signal stability with compatible Hanna instruments.

• Durable Glass Body: Chemically resistant and easy to clean, making the electrode suitable for repeated use across general laboratory applications.

Technical Specifications

Applications

• General Laboratory Testing: Suitable for use in schools, universities, and industrial labs for routine pH measurement tasks.

• Environmental Water Monitoring: Measures pH in natural waters, tap water, and other standard aqueous samples.

• Food & Beverage Industry: Can be used in non-viscous liquids such as juices, beverages, and water-based solutions.

• Water Treatment and Quality Control: Ideal for pH verification in drinking water, wastewater, and purified process water systems.
