Application:
Concrete reinforcement corrosion is the primary factor affecting the durability of concrete.According to statistics, the durability damage of reinforced concrete caused by corrosion accounted for more than 40% of all injuries, while the chloride ion erosion is a major incentive for reinforcement corrosion. DTL concrete chloride ion electric flux detector can be an important indicator for the durability of concrete - concrete to resist chloride ion penetration properties (density) measurements, test indicator is the six-hour power flux (Coulomb)for the concrete specimens, quickly to evaluate the concrete resistance to the chloride ion penetration ability
Product features:
1. Embedded computer control, power outages and power-down data storage, advanced technology, well-made, reliable performance, high accuracy
2. LCD display, with real-time display/print and analysis function, can be separated from Pc to use directly, to facilitate the outdoor field detection.
3. Standard RS232 serial communications with fully automatic PC connection software can output the flux test report to generate curve, and then print for analysis and archiving
4. Automatic short circuit protection to avoid equipment damage
5. Imported material fixture, high accuracy, easy and smart to use
6. Can simultaneously test two groups (6), three (9), four (12) or five (16) concrete block one time
7. With the latest smart-in-one vacuum saturated machine

System Configuration
Concrete Resist Chloride Ion penetration tester
specimen fixture
NJ-BSJ concrete vacuum saturated machine
Test steps:
1． Cut the concrete Standard sample into 50mm thickness test block
2． The sample will be saturated with water in the intelligent concrete vacuum saturated machine
3． After the vacuum saturated, the specimens will be installed on the fixture
4．Inject the concrete solution( NaCl (negative), NaOH (positive) )into the specimen fixed poles
5．Connect the concrete Flux detector power and the positive and negative of specimen fixture
6．Connect the test host, test software control, the test results will be obtained after 6 hours
7．Data is automatically saved and can be printed.
