online nitrate ion detector
The selective electrode of the on-line nitrate ion detector is an effective method to measure the nitrate ion content in samples. Nitrate ion-selective electrodes are also often used in on-line instruments, such as industrial on-line monitoring of nitrate ion content.
Nitrate ion-selective electrode, which has the advantage of simple measurement, fast and accurate response, and can be used with PH meter, ion meter and on-line nitrate ion analyzer.
Application:
nitrate ion selection electrode method for measuring nitrate concentration in solid waste leaching solution; nitrate ion selective electrode method for measuring nitrate ion in coal and ore; nitrate ion selective electrode method for measuring nitrate ions in soil; nitrate ion selective electrode method for detecting nitrate ion in rainfall and surface water; nitrate ion selective electrode method for measuring nitrate ions in vegetables, preserved products and other agricultural products.
