Hanna HI4000-51 Replacement pH Assembly

Hanna HI4000-51 Replacement pH Assembly

The Hanna HI4000-51 Replacement pH Assembly is a replacement pH sensing assembly specifically designed for use in gas-sensing ion-selective electrodes (ISEs), such as those used for ammonia or carbon dioxide measurements. This internal component plays a crucial role in detecting pH changes that occur due to gas diffusion, enabling accurate and responsive gas concentration measurements in liquid samples.

Features

• Specialized for Gas-Sensing ISEs: Functions as the internal pH sensor in gas-selective electrodes, such as ammonia and CO₂ sensors.

• Sensitive pH Detection: Measures changes in pH caused by dissolved gases interacting with a non-buffered electrolyte layer.

• Supports Diffusion-Based Measurement: Operates by tracking pH shifts as dissolved gas equilibrates between the sample and the internal electrolyte layer.

• Easy Replacement: Designed for quick and straightforward replacement to restore electrode performance and accuracy.

• Reliable Output: Ensures consistent and proportional response to the concentration of dissolved gas in the solution.

Specifications

• Product Type: Replacement pH sensing assembly

• Compatible with: Gas-sensing ion-selective electrodes (e.g., ammonia, carbon dioxide ISEs)

• Measurement Principle: pH change due to diffusion of dissolved gas

• Construction: Internal pH sensor component with access to non-buffered electrolyte layer

Applications

The HI4000-51 replacement pH assembly is ideal for:

• Restoring gas-sensing ISE performance in ammonia or carbon dioxide measurements

• Laboratories analyzing dissolved gases in water, wastewater, or process samples

• Research facilities studying gas solubility and equilibrium in liquid media

• Educational institutions demonstrating principles of gas diffusion and pH-based detection

• Industrial quality control in applications involving ammonia or CO₂ concentration monitoring
