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 follows the related standards, such as GB/T
*********8, JGJ*******0, JTJ *****8 and so on. It 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. American imported composite chloride ion selective electrode,
performance stable, testing rapid and accurate.
2. 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;
3. The built-in standard formula can directly calculate the
chloride ion content of concrete mixture
4. Unique linear regression coefficient calculation program can
diagnose the working state by itself
5. 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
6. LCD display, instant printing, one key for completing the
test, simple operation
7. Light and small, convenient for carrying, suitable for the
field detection
8. Optional micro-printer, can also print immediately without
computer
9. Unique self-diagnosis function and PC analysis software
*0. Great data storage capacity can store **0 test data, data is
continuous, safe and reliable
Â
Test object:
Sea sand, ordinary sand, new mixed concrete, hard concrete,
cement, stones, and admixture, concrete mixing water and other
water-soluble material.
Â
Detection principle:
NJCL-H 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.
