On-line calcium ion detector
Calcium ion-selective electrode is an effective method to measure the calcium ion content in a sample. Calcium ion-selective electrodes are also often used in on-line instruments, such as industrial on-line monitoring of calcium ion content.
Calcium ion selective electrode has the advantages of simple measurement and fast and accurate response. It can be used with PH meter, ionometer and on-line calcium ion analyzer. It is also used in the ion selective electrode detector of electrolyte analyzer and flow injection analyzer.
Application:
calcium ion determination of calcium ion selection electrode method in feed water treatment of high pressure steam boiler in power plant and steam power plant; calcium ion selective electrode method to determine calcium ions in mineral water, drinking water, surface water and seawater; calcium ion selective electrode method to determine calcium ions in tea, honey, feed, milk powder and other agricultural products; calcium ion selective electrode method in saliva, serum, urine and other biological samples.
