Applications

The Automatic Four Column Compression Testing Machines are designed for reliable and consistent testing of a wide range of concrete and construction material specimens.

The machines comply with relevant EN, ASTM, and BS standards, and meet CE safety requirements for operator protection.

Testing can be performed either:

• Via the touchscreen digital control unit
• Or through a computer using free PC software

Computer-based testing provides advantages such as graphical output, database management, and advanced reporting.

EASY OPERATION :

After switching on the machine and positioning the specimen:

• Set test parameters (pace rate required only when specimen type changes).
• Press the START button.

The system automatically:

• Performs rapid approach
• Switches to selected loading rate upon specimen contact
• Stops after specimen failure
• Saves test parameters and results automatically
