KSS-Series Conductivity Electrode

  • ABS+316L stainless steel material can naturally oxidize to form chemical passivation, and its conductive surface that is resistant to penetration can withstand all liquids except for fluorinated acids;
  • Temperature compensation components include: NTC2.252/2K/5K/10K/20K/30K/PT100/PT1000, etc., which can be specified by the user;
  • Adopting a large-area (long-distance) platinum structure, it has strong resistance to strong acids and alkalis and strong anti pollution ability, making it convenient for online measurement of conductivity values in special industries.

Core Highlights

  • Corrosion and stain resistance: ABS+316L stainless steel+large-area platinum, resistant to various media other than fluorinated acids.
  • Measurement accuracy: The accuracy of the pool constant is ± 0.02, and the temperature effect is offset by multiple temperature supplements.
  • Wide adaptability: low conductivity range measurement, compatible with multiple instruments and scenarios.
  • Easy installation and maintenance: Standardized 1/2NPT interface, easy to clean and calibrate.

Featured Applications

Ultra-Pure Water Monitoring: KSS0.01 (0.05μS/cm – 10μS/cm) is ideal for ultra-pure water quality analysis in electronics, pharmaceutical, and semiconductor industries.

Pure Water & Low-Conductivity Water Testing: KSS0.1 (0.2μS/cm – 200μS/cm) fits environmental monitoring, pure water treatment, and laboratory water quality analysis.

General-Purpose Water Monitoring: KSS1.0 (2μS/cm – 2000μS/cm) is widely used for conductivity measurement of tap water, industrial circulating water, and conductometric titration in chemical experiments.

High-Conductivity Water Analysis: KSS10.0 (2mS/cm – 200mS/cm) suits high-salinity water, industrial wastewater, and concentrated solution monitoring in chemical, printing, and dyeing industries.

Installation and operation points

  • If you’re not going to use it for a while, put it somewhere dry. To keep the platinum coating, put the electrode in deionized water if you need to store it for a long time.
  • To clean, mix warm water with soap or alcohol to get rid of organic dirt. To get rid of calcium and magnesium buildup, use 10% citric acid. Be careful not to damage the electrode surface.
  • Installation: Before you open, look for damage to the parts. To place, use protective sleeves or cable glands that match. The electrode-wire connection is not waterproof by design, so make sure it is.
  • When you need to calibrate your equipment, you can either use the reference solution approach (which involves making standard calibration solutions) or the comparison method (which involves measuring the same solution with an electrode whose value is known to be constant).

Technical Support

Short term slight overheating (not exceeding 60 ℃ and lasting less than 30 minutes) may cause temporary deviation in measurement data, which can be restored to normal after returning to the rated temperature; If there is long-term or significant overheating, it will accelerate material aging, damage temperature compensation components, and even cause electrode constant drift, permanently affecting measurement accuracy. It is recommended to strictly control the usage temperature within 0-50 ℃. In case of overheating, cooling treatment or replacement of high-temperature resistant electrodes should be done in advance.

There are three common reasons: first, the sensitive part of the electrode is not completely immersed in the water sample, resulting in an air chamber; Secondly, there is oil or scale on the surface of the electrode, which affects signal transmission; The third issue is the incorrect setting of the conductivity cell constant (e.g. the instrument defaults to 1.0, but the actual electrode is 0.1). First adjust the installation position to ensure that the electrode is completely submerged, clean the electrode and recalibrate it, then check whether the electrode constant setting in the instrument is consistent with the product parameters, and troubleshoot one by one to solve the problem.

It is best to use a standard solution that is near to the conductivity value of the water sample you are measuring. In cases of low conductivity, the 141.3 μ S/cm (0.01mol/L KCl) standard solution should be used, and the electrode should be set to a measurement range of 0.2–200 μ S/cm. You can keep the normal solution in a sealed refrigerator for 1 to 2 months after you make it. It needs to be re-prepared if the turbidity, precipitation, or concentration deviation is greater than ± 5% to keep the calibration from being less accurate.

Select based on the target water’s conductivity range: KSS0.01 for ultra-pure water, KSS0.1 for pure/low-conductivity water, KSS1.0 for general-purpose water, and KSS10.0 for high-conductivity water (e.g., concentrated solutions, high-salinity wastewater).
