250,000lbf Automatic Concrete Compression, Flexural and MOE

AC-250 Series Fully Automatic Concrete Compression Machines

The AC-250 Series Fully Automatic Concrete Compression Machines are state-of-the-art solutions for performing comprehensive strength tests on concrete cylinders, beams, cubes, cores, and other sample types with minimal operator intervention. Designed for precision and efficiency, these machines ensure reliable, repeatable, and accurate results while meeting the highest industry standards. Whether you're a materials testing laboratory, construction firm, or educational institution, the AC-250 Series delivers unparalleled performance to streamline your testing processes.

Key Features and Capabilities:

• Automated Testing Process: Start a complete test cycle with a single button on the intuitive touchscreen controller. The machine manages specimen contact, pre-loading, load rate, break detection, data collection, and piston return to the home position.
• Standards Compliance: The AC-250 Series strictly conforms to ASTM, AASHTO, BS 1610, BS 1881, and other industry specifications, eliminating variations in load rates and test procedures.
• Comprehensive Data Management: Test results, including force, stress, and load rate, are displayed in real-time. Optional load vs. time or stress vs. strain graphs provide advanced insights. USB, LAN, and Wi-Fi connectivity allow seamless data transfer, reporting, and immediate printing.
• Enhanced Safety: Operator safety is paramount. Features include an emergency-stop button, hydraulic safety relief valve, piston over-travel limit switch, and transparent fragment guard doors.
• Next-Generation Drive System: The energy-efficient electric motor and hydraulic pump operate at variable speeds, maintaining consistent pressure while reducing noise and heat for extended component life.
• Durable Construction: The rugged, welded steel frame exceeds ACI 363 requirements, ensuring system rigidity and durability. The top-mounted piston prevents damage from test debris, minimizing long-term wear.

Versatile Models to Meet Varied Testing Needs:

1. AC-250 Standard Models: Designed for general compression and flexural strength testing. These units can be enhanced with accessories to accommodate additional testing requirements. 

2. AC-250M and AC-250MR Modified Models: Specifically equipped for advanced testing applications, these models include factory-modified manifolds and optional proportional valves for controlled piston retraction. They support ASTM C469 modulus of elasticity (MOE) testing and Poisson’s ratio determination on 4in or 6in cylinders. Additional accessories, such as Compressometer and Compressometer/Extensometer fixtures, must be purchased separately.

Innovative Testing Features:

• Touchscreen Simplicity: Menu-driven controls enable easy selection of test methods, sample types, and parameters with minimal operator input, improving productivity and reducing errors.
• Dynamic Load Regulation: Feedback mechanisms precisely control load rate and applied force during testing, ensuring consistent results.
• Advanced Diagnostics: The built-in diagnostics feature monitors key systems, including the emergency-stop button, drive system, data communication, pressure transducer, and over-travel limit switch. Fault conditions are clearly indicated and must be resolved before testing continues.
