How to choose suitable Compression Testing Machine?

Compression Testing Machine (CTM) is a critical equipment used in materials testing laboratories. It is designed for testing the compressive strength of building materials such as brick, cement and concrete. The compressive strength is one of the most critical properties that determine the quality and durability of building materials. But how to choose the suitable Compression Testing Machine to ensure the accuracy of the test? In this article, we TBTSCIETECH will guide you in choosing the correct compression testing machine for your concrete testing needs.

1.Choose the load capacity

The load capacity is the maximum amount of force that the machine can apply to the concrete specimen. When choosing a compression testing machine, pay attention to the maximum and minimum load range of the machine. The compression testing machines we offer include TBTCTM-300C、TBTCTM-2000AG、TBTCTM-3000Z, with maximum load capacities of 300kN, 2000kN and 3000kN respectively.

2.Choose the size of load frame

The load frame size is the size of the space where the concrete specimen is placed. Choosing a testing machine with the right load frame size is crucial. You need to consider whether this size matches the size of the concrete specimen you want to test, normally can have sizes as 150mm, 100mm, D150mm*H300mm, D150*H380mm, etc.

3.Choose your standard of reference

When purchasing, you need to pay attention to the technical specifications of the equipment, such as relative error and repeat relative error, to ensure that it meets the requirements of international standards, either ASTM, EN, ISO, or some local country standard, such as IS standard.

4.Choose type

Compression Testing Machine can be with Digital Display and computer control;

Digital display type(TBTCTM-Y2000, TBTCTM-300C) use pressure sensors and LED or LCD displayer, operating is manual.

Computer control(TBTCTM-2000AG, TBTCTM-2000Z) use pressure sensor or spoke type load cell with computer, operating is fully automatic through the software.
