Sensor Component
Highly selective barrier composed of specialized silicate containing lithium ions forms the sensitive bulb of modern pH electrodes used in textile testing. This lithium glass membrane provides a rapid and stable response to hydrogen ions while resisting the chemical attack of hot, highly alkaline finishing liquors. It replaces older sodium-based formulations that suffered from severe measurement errors at high pH levels.
Ion Selectivity
Lithium ions within the glass matrix allow hydrogen ions from the sample solution to exchange with the hydrated gel layer. This selective exchange generates a potential difference that is proportional to the pH of the bath. The chemical structure of the glass minimizes the interference of sodium and potassium ions, ensuring accurate readings during mercerization processes.
Mill Environment
Continuous monitoring of bleaching baths requires sensors that can withstand high temperatures and strong oxidizing agents. The robust nature of the lithium glass membrane ensures consistent performance in these aggressive environments, reducing the frequency of sensor failures. It maintains accuracy even when exposed to abrasive fabric finishes or thick printing pastes.
Durability Factor
Acid washing removes scale without damaging the glass. This simple maintenance procedure extends the useful life of the sensor in busy finishing plants.
