ISO 679 Cement Strength Testing Machine

WTY-300 computerized electronic compression testing machine

1. brief introductions

This testing machine is suitable for use in research institutes, industrial and mining enterprises, etc. It has servo motor drive, low noise, and high precision. The whole machine has a compact structure, easy maintenance, beautiful appearance, high precision, and comprehensive functions, making it an ideal testing instrument for research institutes and cement and mortar production units. 

The testing machine has control modes such as constant testing force, constant stress, and test force maintenance. Implemented functions such as screen display, disk storage, and database management for experimental data and curves.

(Optional function) If equip with flexural test part, it can also do flexural test before compression test.

2.relative test methods about the machine

2.1 GB/T 2611 general requirements for testing machines

2.2 GB/T 17671 test method of cement mortal strength (ISO method)

2.3 GB/T 50081 standard for test methods of concrete physical and mechanical properties

2.4 ASTM C133 standard test methods for cold crushing strength and modulus of rupture of refractories

3. force measuring system

l   Adopting high-precision amplifiers and A/D converters, the entire process is not divided into stages, and real-time display of load, peak value, loading speed, and intensity is available;

l   Adopting closed-loop control strategy to achieve constant speed loading and real-time display of loading curve

l   Automatic interval timing and continuous testing;

l   Flexible and convenient query and printing of test results;

4. protecting function

4.1 overload protection: When the test force exceeds 3% of the maximum test force, the motor stops

4.2 Limit protection: When the displacement reaches the maximum travel limit, limit protection is provided.
