Hanna HI11313 Refillable Glass Body pH Electrode

Hanna HI11313 Refillable Glass Body pH Electrode

The Hanna HI11313 Refillable Glass Body pH Electrode  is a laboratory-grade, refillable combination pH electrode engineered for precision and long-term reliability. Designed with a glass body, double junction, and high-temperature (HT) glass, it excels in a wide range of general-purpose and beverage applications—particularly beer analysis. Moreover, its various connector options make it compatible with a broad selection of Hanna pH meters, including models with temperature compensation and CAL Check™ diagnostics.

Key Features

• Refillable Double Junction Design: Provides extended electrode life and resistance to contamination, especially when measuring protein-rich or complex samples like wort or finished beer.

• High-Temperature (HT) Glass: Optimized for accurate readings across a broad temperature range—from 0 to 100°C—this electrode is ideal for both ambient and heated sample environments.

• Spherical Glass Tip (9.5 mm): Ensures stable and responsive readings on flat or curved surfaces, making it well-suited for beakers, flasks, and sample containers.

• Ceramic Junction with Stable Flow Rate: The 15–20 µL/h flow rate supports consistent performance in aqueous samples.

• Multiple Connection Types:

  • HI11313: Quick Connect DIN with temperature sensor and amplifier

  • HI1131B: BNC connector for general compatibility

  • HI1131P: BNC + pin for CAL Check™-enabled meters

  • HI1131Y: BNC + RCA, featuring a thermistor temperature sensor

• Glass Body: Chemically resistant and easy to clean—ideal for routine lab workflows.

• Amplified Output (HI11313 only): Reduces noise and enhances signal stability in electrically noisy environments.

Technical Specifications

Applications

• Laboratory Research: Ideal for accurate and repeatable pH measurement in chemical, environmental, or biological research.

• Beverage Industry: Particularly well-suited for measuring beer, wort, and other brewing processes due to its high-temperature resistance and anti-contamination design.

• General Water Testing: Used in drinking water, process water, and educational settings for routine pH control.

• High-Temperature Samples: Perfect for samples requiring measurement at elevated temperatures, thanks to HT glass and robust design.
