Four Column Automatic Compression Testing Machines

Four Column Automatic Compression Testing Machines

The PARSROS Automatic range of 2000 kN, 3000 kN, 4000 kN and 5000 kN capacity four column compression testing maªchines have been designed for reliable and consistent testing of a wide range of specimens. These compression testers are the results of continuous research to upgrade the testing machines with the latest techªnologies and conform to the latest standards EN 12390-3, 12390- 4, BS 1881 and ASTM C39 in terms of its technical properties taking into account client requirements. These also meet the requirements of CE norms for health and safety of the operator.
Testing machines are supplied with EN compression platens as standard. Machines also comply with the ASTM C39 standard when used together with suitable platens ( see page 128 ).
Tests can be performed by either on Hydaulic Unit or on a computer with using free PARSROS Software. The advantages of performing tests on computer with using PARSROS Software, such as reporting, graphical output, etc.,

The PARSROS Automatic range of 2000 kN, 3000 kN, 4000 kN and 5000 kN capacity four column compression testing machines allow inexperienced operators to perform the tests. Once the machine has been switched on and the specimen is positioned and centered by the help of centering apparatus. The only required operations are;
• Setting test parameters, including pace rate (only required when the specimen type is changed).
• Pressing the START button on the control unit
• The machine automatically starts the rapid approach, when the specimen touches the upper
platen the rapid approach is ended and starts loading at the pace rate that selected by user and stops once the specimen fails.
• Automatically saves the test parameters and test results
•
All models are supplied in Class 1 starting from 50 kN as standard EN 12390-3, 12390-4, BS 1881 and ASTM C39. PARSROS range of Semi-Automatic and Automatic Machines can be upgraded with option PRS-B0210 special calibration Class 1 starting from 1% of the full range. This exceptional performance enables the machines to be used for a considerable number of applications including:
• Early age compression strength tests
• Flexural tests by using proper accessories
• Mortar (Cement) compression tests by using proper accessories
• Core with low diameter compression tests
The compression machines consist of a heavy duty four column frame, automatic hydraulic power pack with data acquisition and control system.
