Test method: ISE( Ion Selective Electrode) Test indicators: concentration of chloride ions, the percentage of quality Product introduction: Chloride ion is one important factor to induce reinforcement corrosion. In order to avoid premature reinforcement corrosion, chloride ion in the concrete raw material must be controlled very strictly. The related standards in our country have clear requirements to test chloride ion when chooses the raw materials, such as the matching sand, aggregate concrete, cement and admixture, mixing water, fundamentally avoid adding excessive chloride ion into the concrete. The test of the chloride ion content in concrete structure plays a significant role for the evaluation of the structure safety, and provides the extreme reference value basis for the renovation and repair of the old structure at the same time. The instrument adopts the ISE (Ion Selective Electrode) method to rapidly test the water soluble chloride ion content of the inorganic material in room temperature, such as concrete, sand, cement, mixing water, by the equipped professional software and anti-interference chemical reagents, to achieve the purposes of prevention and control of premature concrete reinforcement corrosion occurrence.
