About Conductivity Standard - 25 mhos/cm

Conductivity Standard - 25 mhos/cm is an analytical-grade solution designed for precise calibration of conductivity meters and sensors. This clear, colorless liquid is composed of high-purity deionized water blended with trace amounts of potassium chloride to ensure a stable and standardized conductivity level of 25 mhos/cm at 25C. It is odorless, non-poisonous, and completely soluble in water, making it safe and easy to use in laboratory and industrial environments. The solution retains a neutral pH of ~7 and has a density of 1.00 g/cm, closely matching water. Ideal for applications requiring accurate conductivity measurement, the product is stable under proper storage conditions and offers a shelf life of up to 12 months when stored at room temperature in tightly sealed containers to prevent contamination. Compliant with chemical standards, it carries CAS numbers 7732-18-5 and 7447-40-7 for its components, along with HS Code 3822.00.00 for international standard solutions.
