Chloride Ion Selective Electrode (ISE)

NT Sensors is a leading manufacturer of high-quality and reliable chloride ion selective electrodes.

Our electrodes are based on the latest nanotechnology research and are designed to provide accurate and fast measurements of chloride concentrations in aqueous solutions.

With our chloride ion selective electrodes, you can easily and quickly determine the salinity levels of water samples. This makes them ideal for a wide range of applications, including determining the concentration levels in ocean saltwater, seawater aquariums, salt in food samples, and clinical and laboratory analysis of urine, sweat, and blood, among others.

Our chloride ion selective electrodes are also effective for plant tissue analysis when dissolved in an aqueous solution. Additionally, chloride is a slow-reacting element and is not absorbed into the soil, making it easily transported and propagated through water. This makes it an effective tracing element for detecting dangerous chemical substances and the intrusion of high salinity water.

At NT Sensors, we pride ourselves on providing the highest quality products to our customers. Our chloride ion selective electrodes are designed for ease of use and reliability. They are also designed to have a long shelf life, making them an ideal solution for your chloride ion measurement needs. If you are looking for the best quality in chloride ion selective electrodes, look no further than NT Sensors.

Where is chloride measurement required so far?

The concentration of the Chloride ion gives a quick measurement of salinity of water samples. Use the Chloride ISE to measure chloride levels in ocean saltwater, wastewater or salt in food samples.

Also, the production of concrete can also require chloride testing because high levels of chloride can corrode the metal reinforcements that are present within a concrete structure.

We can measure the concentration of chloride in:
– Drinks and juices
– Paper industry
– Geology and mining
– Petroleum refining and gas production
– Power engineering
