The selective electrode of the on-line lead detector is an effective method to measure the lead ion content in samples. Lead ion-selective electrodes are also often used in on-line instruments, such as industrial on-line monitoring of lead ion content.
Lead ion selective electrode, with the advantages of simple measurement, fast and accurate response, can be used with PH meter, ionometer and on-line lead ion analyzer, and is also used in the ion selective electrode detector of electrolyte analyzer and flow injection analyzer.
Can be applied to:
industry, environmental protection, education, agricultural Internet of Things and other industries.
