ASTM C1202-12 Standard Test Method for Electrical Indication of Concrete's Ability to Resist Chloride Ion Penetration

Detection method: electricity

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) concrete block one time
7. With the latest smart-in-one vacuum saturated machine

Technical parameters:
