Chloride ion is a critical factor in inducing reinforcement corrosion. To prevent premature reinforcement corrosion, chloride ion content in concrete raw materials must be strictly controlled. Our national standards mandate chloride ion testing for raw materials including sand, aggregate concrete, cement, admixtures, and mixing water to fundamentally prevent excessive chloride ion introduction.

This instrument employs the ISE (Ion Selective Electrode) method to rapidly test water-soluble chloride ion content in inorganic materials such as concrete, sand, cement, and mixing water at room temperature. Using professional software and anti-interference chemical reagents, it effectively prevents and controls premature concrete reinforcement corrosion.

• Tests chloride ion content in concrete mixtures, hardened concrete, gravel, admixtures, water, and other water-soluble materials with direct output of mol concentration and percentage unit results
• Built-in standard formula for direct calculation of chloride ion content in concrete mixtures
• Special ion anti-interference agent eliminates oxidation effects of cyanogens and ammonia, and removes complexation effects of manganese, lead, and other metal ions
• LCD display with instant printing and one-key operation for simplified testing
• Lightweight and compact design for convenient field detection
• Optional micro-printer for immediate printing without computer
• Unique self-diagnosis function with PC analysis software
• Extensive data storage capacity for 100 test records with continuous, safe, and reliable data management

The rapid concrete chloride tester utilizes the ISE (Ion Selective Electrode) method to quickly test chloride ion content in concrete, sandstone, admixtures, and other water-soluble materials. Operating within a chloride ion concentration range of 10⁻⁵ to 10⁻¹ mol/L, this method provides simple operation suitable for field detection with accurate, rapid results and automatic data processing.
