Advanced Rapid Chloride Permeability Tester (RCPT) System
Standard Compliance: ASTM C1202, AASHTO T277, ASTM C1760
The Rapid Chloride Permeability Tester (RCPT) system is engineered to evaluate the electrical conductance and resistance of concrete specimens against chloride ion penetration. By accelerating chloride migration using a 60 V DC electric field over a 6-hour test cycle, the system provides rapid quantitative data to determine the long-term durability of concrete structures exposed to aggressive or marine environments.
Key Features
- Simultaneous Multi-Channel Testing: Available in 4, 6, or 12-channel configurations to test multiple concrete samples concurrently.
- Automated Data Logging: Automatically logs current, voltage, and temperature profiles at preset intervals (every 30 minutes) and computes total charge passed in Coulombs.
- Safety Protection: Integrated short-circuit and over-current protection on every individual channel.
- Advanced Software Integration: Real-time graphical plotting (Current vs. Time) with direct report export options to Excel and PDF formats.
- Rigorous Sample Preparation Kit: Includes a heavy-duty vacuum desiccator and high-capacity vacuum pump for specimen water-saturation as required by standards.
