Test method:ISE( Ion Selective Electrode)

Test indicators:Concentration of chloride ions, the percentage of quality

Product model:NJCL-C

  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.

1. Can test the chlorine ion content of concrete mixture, hard concrete, gravel, admixture, water, and the other water-soluble material, directly output the mol concentration and percentage unit results;

2. The built-in standard formula can directly calculate the chloride ion content of concrete mixture

3. Special ion anti-interference agent can remove the oxidation effect of cyanogens and ammonia, and remove the complexation effect of manganese, lead and other metal ion

4. LCD display, instant printing, one key for completing the test, simple operation

5. Light and small, convenient for carrying, suitable for the field detection

6. Optional micro-printer, can also print immediately without computer
