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
Test object:
Sea sand, ordinary sand, new mixed concrete, hard concrete,
cement, stones, and admixture, concrete mixing water and other
water-soluble material.
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
