Model DTL-A CHLORIDE PENETRATION METER
STANDARD:ASTM C1202, AASHTO T277
This test method allows evaluation of chloride permeability characteristics of concrete. The test is performed to monitor the amount of electrical current passing through concrete cores or cylinders. A potential difference is maintained across the ends of the specimen, one of which is the negative end and is immersed in a sodium chloride solution, the other (positive end) in a sodium hydroxide solution. The total charge passed, in Coulombs, that is related to the resistance of the specimen to chloride ion penetration is measured.
Measuring technique
closed loop maintained 60 V DC potential difference, passed current measured and integrated relative to time.
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
VACUUM SATURATED MACHINE
The intelligent concrete vacuum saturation machine is used for the saturation treatment of the concrete test block, and for the early saturation of the concrete chloride ion electric flux and diffusion coefficient experiment. The main chip adopts a microprocessor, the whole process is controlled automatically, and it can also be manually set and operated, and the operation is simple. 12 test blocks can be saturated with water in a single test.
