Hanna HI4000-54 Replacement pH Assembly
The Hanna HI4000-54 Replacement pH Assembly is a replacement combination pH assembly designed specifically for the HI4105 Carbon Dioxide Gas-Sensing Ion Selective Electrode (ISE). This component integrates both a pH-sensitive membrane and a stable reference electrode, ensuring accurate and reliable CO₂ measurements through pH shift detection within the gas sensor.
Features
Combination pH Design: Includes both the sensing and reference elements in a single internal assembly, simplifying installation and ensuring measurement integrity.
High-Sensitivity pH Membrane: Detects changes in pH caused by dissolved CO₂ interacting with the internal electrolyte, enabling precise gas concentration readings.
Stable Reference Electrode: Ensures consistent signal output for accurate and repeatable measurements.
Specifically Designed for CO₂ ISE: Fully compatible with the HI4105 carbon dioxide ion selective electrode, making it the correct replacement part for performance restoration.
Easy Replacement: Simple to install into the electrode body for quick maintenance and minimal downtime.
