CS6510 Fluoride Ion Sensor
The fluoride ion selective electrode is a selective electrode sensitive to the concentration of fluoride ion, the most common one is the lanthanum fluoride electrode.
Lanthanum fluoride electrode is a sensor made of lanthanum fluoride single crystal doped with europium fluoride with lattice holes as the main material. This crystal film has the characteristics of fluoride ion migration in the lattice holes.
Therefore, it has very good ion conductivity. Using this crystal membrane, the fluoride ion electrode can be made by separating two fluoride ion solutions. The fluoride ion sensor has a selectivity coefficient of 1.
And there is almost no choice of other ions in the solution. The only ion with strong interference is OH-, which will react with lanthanum fluoride and affect the determination of fluoride ions. However, it can be adjusted to determine the sample pH <7 to avoid this interference. -

CS6521 Nitrite electrode
The nitrite ion-selective electrode (ISE) is a specialized analytical sensor designed for the direct potentiometric measurement of nitrite ion (NO₂⁻) concentration in aqueous solutions. It is a critical tool in environmental monitoring, water treatment, food safety, and agricultural science, where nitrite levels serve as a key indicator of water pollution, process control in wastewater denitrification, and food preservation quality.
The core of a modern nitrite ISE is typically a polymer membrane or a crystalline solid-state sensor body impregnated with a nitrite-selective ionophore. This proprietary chemical component selectively binds nitrite ions, creating a potential difference across the membrane relative to a stable internal reference electrode. This measured voltage is logarithmically proportional to the activity (and thus concentration) of nitrite ions in the sample according to the Nernst equation.
A significant advantage of the nitrite ISE is its ability to provide rapid, real-time analysis without the need for complex sample preparation or colorimetric reagents required by traditional methods like the Griess assay. Modern electrodes are designed for both laboratory benchtop use and integration into online, continuous monitoring systems. However, careful calibration across the intended measurement range and awareness of potential interferences from ions like chloride or nitrate (depending on the membrane selectivity) are essential for obtaining accurate results. When used correctly, it offers a robust, cost-effective solution for the dedicated, routine measurement of nitrite.

CS6514 Ammonium ion Sensor
Ion selective electrode is a kind of electrochemical sensor that uses membrane potential to measure the activity or concentration of ions in the solution. When it comes into contact with the solution containing the ions which are to be measured, it will generate contact with the sensor at the interface between its sensitive membrane and the solution. Ion activity is directly related to membrane potential. Ion selective electrodes are also called membrane electrodes. This type of electrode has a special electrode membrane that selectively responds to specific ions. The relationship between the potential of the electrode membrane and the ion content to be measured conforms to the Nernst formula. This type of electrode has the characteristics of good selectivity and short equilibrium time, making it the most commonly used indicator electrode for potential analysis. -

ISE Sensor Calcium Ion Water Hardness Electrode CS6518A Calcium Ion Electrode
The Hardness (Calcium Ion) Selective Electrode is a vital analytical sensor designed for the direct and rapid measurement of calcium ion (Ca²⁺) activity in aqueous solutions. While often termed a "hardness" electrode, it specifically quantifies free calcium ions, which are the primary contributor to water hardness. It is extensively used in environmental monitoring, industrial water treatment (e.g., boiler and cooling systems), beverage production, and aquaculture, where precise calcium control is crucial for process efficiency, equipment scaling prevention, and biological health.
The sensor typically employs a liquid or polymer membrane containing a selective ionophore, such as ETH 1001 or other proprietary compounds, which preferentially complexes with calcium ions. This interaction creates a potential difference across the membrane relative to an internal reference electrode. The measured voltage follows the Nernst equation, providing a logarithmic response to calcium ion activity within a wide concentration range (typically from 10⁻⁵ to 1 M). Modern versions are robust, often featuring solid-state designs suitable for both laboratory analysis and continuous online process monitoring.
A key advantage of this electrode is its ability to deliver real-time measurements without time-consuming wet chemistry, such as complexometric titrations. However, careful calibration and sample conditioning are essential. The ionic strength and pH of samples must often be adjusted using a special ionic strength adjuster/buffer to stabilize pH and mask interfering ions like magnesium (Mg²⁺), which can affect the reading in some designs. When properly maintained and calibrated, the calcium ion-selective electrode offers a reliable, efficient, and cost-effective method for dedicated hardness control and calcium analysis across numerous applications.
