Nitrite ion-selective electrode is an effective method to measure the nitrite ion content in a sample. Nitrite ion-selective electrodes are also often used in on-line instruments, such as industrial on-line monitoring of nitrate ion content.
Nitrite ion-selective electrode, with the advantages of simple measurement, fast and accurate response, can be used with PH meter, ionometer and on-line nitrite ion analyzer.
Application:
nitrite ion selection electrode method for measuring nitrite concentration in solid waste extraction solution; nitrite ion selective electrode method for measuring nitrite ions in vegetables, preserved products and other agricultural products.
