Test method:ISE( Ion
Selective Electrode)
Test
indicators:Concentration of chloride ions,
Product model:NJCL-L
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.
Feature
1. Can rapidly test the chloride ion concentration in *0second
2. LCD display, instant printing, one key for completing the
test, simple operation
3. Unique self-diagnosis function and PC analysis software
4. 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
5. Build-in micro-computer can print immediately, simple
operation
6. Great data storage capacity can store **0 test data, data is
continuous, safe and reliable
Detection principle:
NJCL-L Rapid concrete chloride tester adopts the ISE (ion
selective electrode) method rapidly to test the chlorine ion
content of concrete, sandstone, admixture and the other
water-soluble matters. The range of chlorine ion concentration is
***5 ~ ***1 MÂ mol/L. Operation is simple, and can be used in
the field detection, data accurate and rapid, automatic data
processing.
Test object:
Sea sand, ordinary sand, new mixed concrete, hard concrete,
cement, stones, and admixture, concrete mixing water and other
water-soluble material.
