Magnesium ion selective electrode (ISE)

For accurate and reliable measurement of Magnesium ions in aqueous solutions, turn to NT Sensors’ Magnesium Ion Selective Electrode (ISE Magnesium). Our ISE Magnesium is built on the foundation of our team’s years of experience in developing high-quality electrochemical sensors.

With its high selectivity towards Magnesium ions, our ISE Magnesium is perfect for a wide range of applications, including perforation muds, mining, drinking water, mineral water, seawater, and nutrient analysis in agriculture.

One of the significant advantages of our ISE Magnesium is its ability to provide precise measurements of water hardness. As Magnesium and Calcium ions are the most significant contributors to water hardness, our ISE Magnesium can help in determining the overall hardness of a sample through a mathematical formula.

Our Magnesium ion selective electrode has a rapid response time of less than 60 seconds, making it easy to obtain accurate results quickly. Additionally, the sensor requires only a small sample volume, and its dry-storage feature ensures convenient and hassle-free usage.

At NT Sensors, we strive to provide high-quality and affordable solutions to meet your electrochemical sensor needs. Contact us today to learn more about our ISE Magnesium ion selective electrode and how it can benefit your specific application.

Where is Magnesium measurement required so far?

The magnesium ion selective electrode sensor is designed to provide increased accuracy in water hardness, drilling muds, mining, drinking water, mineral water and seawater. The Mg+2 ISE can also be accurately applied to the monitoring of total water hardness assessments.Also, it is mainly found in mineral deposits.
Finally, magnesium plays an important role in both plants and animals. In plants, magnesium is the central ion of chlorophyll. In vertebrates, magnesium is essential, especially within cells. Magnesium is also widely used for technical and medical applications ranging from the production of alloys, pyrotechnics and fertilisers to health care.
